			<content:encoded><![CDATA[<p>Earlier today, <a href="http://www.nicira.com/" target="_blank">Nicira</a> publicly emerged as a company from stealth mode with more than just an idea,  but with a product and several customers actually using it. While many find that  approach old school, I like the fact that they are more than just  PowerPoint slides and buzzword bingo press releases. I like that they waited to  publicly announce the company until they had built a working product and  actually sold it to some customers. I wish more companies would do that.</p>
<p>Granted, information about the company has been around for a while, including  an article in the New York Times last fall describing how NTT, in the wake of  the Tsunami disaster, has been able to effectively leverage Nicira to maintain  availability in the midst of rolling data center blackouts.  According to  Nicira, other large service providers are also enamored with this  technology, citing AT&amp;T, eBay and Rackspace as customers as  well. Nicira also cites a large enterprise customer, Fidelity, among those that  have adopted its technology.</p>
<p>Why have these very large and well known service providers selected to work  with Nicira? Simply put, because Nicira is helping them solve a very large, and  fairly well known problem – network complexity in rapidly scaling, highly  dynamic virtual environments. My colleague Jon Oltsik  has defined this as Data  Center Network Discontinuity. As organizations continue to consolidate data  centers, drive increased use of server virtualization technology, and increase  their ability to react more quickly to business needs, legacy network solutions  will reach a breaking point. Something needs to change in order to drive new and  sustainable growth.  Organizations will need to create a virtual network  platform to fully abstract the physical layer from the logical one, instead of  an even bigger maze of individual boxes.</p>
<p>OpenFlow and Software Defined Networking hold a lot of promise in this  regard. Many companies, including HP and IBM/NEC, are leveraging this  technology and have recently made some big announcements, while other companies  like Arista, BigSwitch, and Juniper have been pursuing their  own implementations. Nicira hopes its model will take network virtualization to  a whole new level. By placing the intelligence in the virtual switch and  leveraging an external controller, Nicira hopes to virtualize (and commoditize)  the underlying physical network.</p>
<p>By taking this approach, Nicira proves that it has no hardware agenda  and therefore organizations do not have to rip and replace any equipment. It can  be deployed in conjunction with existing technology from any vendor. As the  customer list suggests, large service providers with cloud environments will  receive the most benefit, but those enterprises that have committed to and  deployed their own private clouds could take advantage of this technology as  well, like Fidelity has done. As more enterprises consolidate data centers and  mature their server virtualization environments, I would expect to see more  enterprise logos pop up on its website, if the technology works as advertised  with its initial customers.</p>

			<content:encoded><![CDATA[<h1>Optimizing Server, Application, and Storage Consolidation with Edge Virtual Server Infrastructure</h1>
<div class="abstract">Riverbed Technology provides a performance platform for enterprises implementing strategic initiatives such as virtualization, consolidation, cloud computing, and disaster recovery in a globally connected enterprise. Riverbed solutions are designed to enable a fluid, dynamic IT architecture by eliminating bottlenecks and increasing the performance of a full range of business applications including e-mail, ERP, CRM, backup, and file sharing. This ESG Lab Validation examines Riverbed’s WAN optimization and Virtual Services Platform (VSP) as well as the Riverbed Granite edge virtual server infrastructure that enables organizations to consolidate storage considered impossible to consolidate due to the response time requirements of branch-bound applications that rely on local storage.</div>
<h2>Background</h2>
<p>While IT priorities and challenges are often considered with data centers and other centralized corporate resources in mind, it is important to remember that organizations often have distributed locations that have significant and complex computing requirements. In fact, typical IT challenges are often exacerbated in these remote/branch offices due to distance and lack of onsite IT staff. ESG research found that companies face significant challenges when it comes to delivering applications over the WAN from a central location to employees at branch office locations. According to a recent ESG survey,<a href="#_ftn1"><sup><sup>[1]</sup></sup></a> nearly half of respondents identified improving application performance for end-users as a key initiative (see Figure 1). Improvements to application accessibility and better collaboration capabilities were also high on the list.</p>
<div class="graph_top">Figure 1. Top Remote Office/Branch   Office IT Priorities</div>
<p><img class="alignnone size-full wp-image-28293" title="RiverbedSteelheadEXf1" src="http://www.enterprisestrategygroup.com/media/wordpress/2012/02/RiverbedSteelheadEXf1.png" alt="" width="650" height="487" /></p>
<h2>Riverbed Steelhead EX + Granite Overview</h2>
<p>Riverbed Technology’s Steelhead product family is designed to provide increased application performance and data transfer speeds over the WAN. Steelhead products address four main solution areas.</p>
<ul>
<li><strong>Application Acceleration</strong><strong>—</strong>Steelhead optimizes both TCP and UDP traffic, addresses application-specific latency, delivers LAN-like performance and availability over the WAN, and enables improved collaboration, file sharing, and productivity for distributed enterprises.</li>
<li><strong>Bandwidth Optimization</strong><strong>—</strong>enables network managers to achieve better utilization of existing WAN bandwidth by eliminating redundant WAN traffic.</li>
<li><strong>IT Infrastructure Consolidation</strong><strong>—</strong>enables consolidation of IT infrastructure from remote offices to a centrally located facility, maintaining performance, availability, and security, as well as reducing capital expenditure and management costs.</li>
<li><strong>Backup &amp; Replication Acceleration</strong><strong>—</strong>enables quick and secure backup and replication from branch locations.</li>
</ul>
<div class="graph_top">Figure 2.   Riverbed Steelhead</div>
<p><img class="alignnone size-full wp-image-28294" title="RiverbedSteelheadEXf2" src="http://www.enterprisestrategygroup.com/media/wordpress/2012/02/RiverbedSteelheadEXf2.png" alt="" width="653" height="210" /><br />
The Riverbed Steelhead family of products is designed to optimize WAN traffic between distributed remote and branch office locations and a central data center. Steelhead appliances run the Riverbed Optimization System (RiOS), which is the software platform that enables data-, protocol-, and application-level WAN optimization and allows a central office to consolidate the majority of its remote office server infrastructure, taking the first step toward true infrastructure consolidation. Riverbed Steelhead EX combines WAN optimization capabilities with VMware on the appliance, enabling a branch to virtualize local servers and minimize the bandwidth required by users and applications.</p>
<div class="graph_top">Figure 3.   Riverbed Steelhead EX + Granite</div>
<p><img class="alignnone size-full wp-image-28295" title="RiverbedSteelheadEXf3" src="http://www.enterprisestrategygroup.com/media/wordpress/2012/02/RiverbedSteelheadEXf3.png" alt="" width="632" height="258" /><br />
Granite was developed by Riverbed to deliver edge virtual server infrastructure that extends an enterprise storage area network (SAN) out to remote offices. It enables organizations to centralize and consolidate branch office storage at a primary data center. Steelhead EX + Granite combines Riverbed Steelhead and Granite software capabilities with the goal of serving write-intensive and custom applications in the branch with a global storage infrastructure projected from the data center, eliminating storage at remote branch offices previously considered too difficult to consolidate.</p>
<h1>ESG Lab Validation</h1>
<p>ESG Lab performed hands-on evaluation and testing of the Riverbed Steelhead EX + Granite WAN optimization and storage consolidation appliance at a Riverbed facility in San Francisco, California. Testing was designed to demonstrate how Steelhead EX + Granite improves application performance and availability, as well as delivers infrastructure consolidation and data security for branch locations in a distributed enterprise.</p>
<h2>Getting Started with WAN Optimization</h2>
<p>Steelhead appliances at remote locations, along with Steelhead Mobile software on remote user laptops, work together with one or more Steelhead appliances in the corporate data center to optimize traffic flowing over the WAN. Riverbed addresses three areas that affect WAN efficiency: application chattiness, data redundancy, and transport protocol inefficiency.</p>
<p>To speed application performance, application-specific optimizations complete transactions locally in the branch on behalf of servers in the data center, eliminating the need to wait for application responses over a WAN connection. To reduce the amount of data sent over a WAN, Steelhead appliances and software intercept and inspect WAN data to determine whether the data or a portion of it has been seen before. When a user attempts to access data already encountered by the local Steelhead datastore, the data is served locally, eliminating the delay of pulling data over the WAN. With this capability, Steelhead appliances allow users and applications to read and manipulate data, while only requesting or sending unique blocks across the WAN. To overcome transport protocol limitations, Steelhead appliances more intelligently scale and pack TCP payloads, significantly reducing round trips and more efficiently transmitting data across the WAN.</p>
<p>Figure 4 shows the test bed used by ESG Lab, which consisted of a simulated data center and remote office. A Network Nightmare WAN simulation device was used to limit bandwidth and inject latency, simulating a transcontinental T1 link. The data center was configured with one NetApp FAS 2050 connected to both Steelhead and Granite core appliances. The remote office had a Steelhead EX + Granite appliance running Steelhead WAN optimization software, Granite block-storage acceleration, and the Riverbed VSP. The connection between the two environments was limited to 1.5 Mbps (T1 equivalent) and had 100 milliseconds of round-trip latency injected to simulate a remote office connecting to a data center up to 3,000 miles away.</p>
<div class="graph_top">Figure 4. The ESG Lab Test Bed</div>
<p><img class="alignnone size-full wp-image-28296" title="RiverbedSteelheadEXf4" src="http://www.enterprisestrategygroup.com/media/wordpress/2012/02/RiverbedSteelheadEXf4.png" alt="" width="645" height="220" /><br />
<strong><em><br />
</em></strong></p>
<h3>ESG Lab Testing</h3>
<p>For the first round of tests, Steelhead WAN optimization was used to optimize typical knowledge worker operating tasks. Data reduction and optimization-related metrics were captured using the Steelhead management console as well as wall-clock timing of certain operations. As shown in Figure 5, simple file transfers, Microsoft Exchange messages with attachments, and Microsoft SharePoint transaction performance were measured with and without Riverbed Steelhead WAN optimization enabled. The corresponding results show performance improvements of anywhere from 5X to 50X, depending on the type of transaction.</p>

The data in Table 1 includes the sizes of the objects used in performance testing and the number of seconds to completely execute each operation. The largest time reduction was seen with the transfer of a 65.3 MB file from a remote client to the corporate file server.</p>

<h1>Why This Matters</h1>
<p>Today’s enterprises are working toward infrastructure   consolidation to improve resource utilization, security, and cost reduction. Organizations   with distributed enterprise environments (with numerous remote users and   offices) have the same goal but face the added challenge of users from a   remote office connecting to the data center over the WAN. In an ESG survey of   IT administrators in distributed environments, 48% of respondents identified improving application   performance for remote end-users as a key initiative.<a href="#_ftn2"><sup><sup>[2]</sup></sup></a> The need   to consolidate servers from remote sites yet maintain application response times—while   still reducing costs—has driven many organizations to look at WAN   optimization. Riverbed Technology’s Steelhead EX + Granite WAN optimization   appliance enables IT administrators to consolidate servers while maintaining   performance without the added cost of more bandwidth.</p>
<p>ESG Lab has confirmed through hands-on testing and   actual production use that Riverbed Steelhead solutions provide outstanding   WAN data reduction. Whether leveraged to avoid costly network upgrades or   used to quickly access important data, Riverbed Steelhead solutions enable   greater performance and productivity for remote offices. ESG used Steelhead   Appliances to optimize WAN connectivity and improved performance by up to 50   times, demonstrating how the solution enables more productive collaboration   between remote and central offices.</td>

<h2>Consolidation of Branch Services</h2>
<p>Organizations are using server virtualization to simplify their IT infrastructures while reducing costs in their data centers through consolidation. For services required in branch offices, consolidation (minimizing infrastructure in the branches) is also a key goal. However, organizations are faced with a challenge in that certain applications require local compute and storage resources to meet performance requirements for end-users. Steelhead EX features the Riverbed Virtual Services Platform (VSP) that incorporates VMware virtualization technology to consolidate branch servers and applications onto the Steelhead EX appliance.</p>
<h3>ESG Lab Testing</h3>
<p>ESG Lab began testing the ease of consolidating branch office services and applications using Riverbed Steelhead + Granite technology by simulating the user experience of moving from a traditional branch office with dedicated servers, applications, and local storage to a virtualized Riverbed WAN-optimized and consolidated model, as illustrated in Figure 6.</p>
<div class="graph_top">Figure 6.   Branch Service Consolidation with Steelhead EX + Granite</div>
<p><img class="alignnone size-full wp-image-28298" title="RiverbedSteelheadEXf6" src="http://www.enterprisestrategygroup.com/media/wordpress/2012/02/RiverbedSteelheadEXf6.png" alt="" width="650" height="280" /><br />
ESG Lab first virtualized a Microsoft Windows Server 2008 system in the remote location by installing the VM onto the Riverbed VSP. This is accomplished via the Steelhead management interface. The Steelhead EX + Granite appliance can host up to five end-user virtual machines. ESG Lab connected to the Steelhead EX + Granite appliance through the Riverbed Steelhead Management Console to install the virtual server as shown in Figure 7.</p>
<div class="graph_top">Figure 7. Steelhead Management   Console: Loading a Virtual Machine</div>
<p><img class="alignnone size-full wp-image-28299" title="RiverbedSteelheadEXf7" src="http://www.enterprisestrategygroup.com/media/wordpress/2012/02/RiverbedSteelheadEXf7.png" alt="" width="655" height="337" /><br />
Once the virtual machine was loaded and running, ESG Lab simulated a Microsoft SQL server workload using the Iometer load generation utility. SQL Server is an application that, due to the response-time sensitivity of transactional databases, is often hosted on physical servers with local storage in a branch office. In this test, a 4 KB block size was used with a 67% read, 100% random access pattern.</p>
<p>Figure 8 shows the Iometer results displayed during the test. The most important metric to note here is “Average I/O Response Time (ms).” While the back-end connection to the storage array was over a simulated T1 connection with 100 ms of round-trip latency, Iometer reports only 31 milliseconds of latency to disk because data is being written to the local Steelhead blockstore.</p>
<div class="graph_top">Figure 8. Running a SQL Server over   WAN-extended SAN Storage</div>
<p><img class="alignnone size-full wp-image-28300" title="RiverbedSteelheadEXf8" src="http://www.enterprisestrategygroup.com/media/wordpress/2012/02/RiverbedSteelheadEXf8.png" alt="" width="650" height="382" /><br />
It’s important to note here that without Steelhead EX + Granite, ESG Lab was unable to obtain a usable result due to the restricted bandwidth and high latency of the WAN link. In fact, the connection to the LUN in the data center timed out, and the mount failed.</p>

<td width="706" valign="top">
<h1>Why   This Matters</h1>
<p>ESG research   indicates that two of the top three challenges that IT managers face when trying   to deliver IT services to remote and branch offices are poor application   performance and the cost of WAN bandwidth.<a href="#_ftn3">[3]</a> Our research also indicates that spending   more on WAN bandwidth doesn’t always fix the performance problem. As a matter   of fact, 56% of organizations cite poor application performance as a   challenge—regardless of whether they are spending less than $1,000 or more   than $5,000 per month on WAN bandwidth.</p>
<p>When   running an OLTP database workload in a Riverbed appliance-hosted virtual   machine, Riverbed Steelhead   EX + Granite technology provided   LAN-like access to the database volume over a simulated WAN link. Latency   to the storage decreased by more than 67%, making it possible to consolidate   business-critical branch services over the WAN.</td>

<h2>Consolidating Branch Office Storage</h2>
<p>Riverbed Granite extends iSCSI block storage from the data center to the remote site in a way that is transparent to users and applications, and that takes advantage of Riverbed Steelhead WAN optimization technology. Granite enables organizations to maintain local servers at branch offices while actually storing and protecting their data within their data centers. Riverbed VSP provides the ability to host those servers directly on the Steelhead EX appliance.</p>
<h3>ESG Lab Testing</h3>
<p>ESG Lab tested Granite by mounting iSCSI LUNs from the data center on physical branch server nodes as well as within the virtual machines hosted in the Steelhead EX + Granite appliance. To verify the challenge of accessing “unoptimized” iSCSI storage over the WAN, ESG Lab first attempted to mount an iSCSI LUN directly from a traditional branch server to a data center SAN without Granite, and observed that the connection timed out and the mount failed.</p>
<p>Next, ESG Lab tested whether Riverbed Granite could allow the use of iSCSI over the WAN by configuring Granite appliances in both a data center and a remote office location. Figure 9 shows the basic functional design of storage extended with Granite. In effect, there are two iSCSI connections (working from right to left):</p>
<ul>
<li>Within the data center (right), between the actual iSCSI SAN target to the Granite core iSCSI initiator.</li>
<li>Within the remote site (left), between the production server iSCSI initiator to the Steelhead EX + Granite iSCSI target.</li>
</ul>
<p>Using the same branch server, ESG Lab was able to successfully mount with no errors or timeouts the same iSCSI LUN that had previously failed to mount in the “unoptimized” test.</p>
<div class="graph_top">Figure 9. Extending Block-Level Storage from   the Data Center via Steelhead EX + Granite</div>
<p><img class="alignnone size-full wp-image-28301" title="RiverbedSteelheadEXf9" src="http://www.enterprisestrategygroup.com/media/wordpress/2012/02/RiverbedSteelheadEXf9.png" alt="" width="640" height="264" /><br />
The combination of Granite with Steelhead WAN optimization makes it possible for a data center LUN to be successfully mounted by a remote office production server—either a physical server located in the branch or one that is virtually hosted within the Riverbed VSP hypervisor.</p>
<p>Next, ESG Lab examined performance and usability. For this test, ESG Lab (working <em>right to left</em> in Figure 9):</p>
<ol>

</ol>
<p>From there, the LUN behaved like any other iSCSI-attached device and could be mounted and utilized. A common concern about remote storage is that the latency associated with initial use or access requests will have an impact on the end-user experience. To observe the behavior, ESG Lab configured an extended LUN within Steelhead EX + Granite that contained a known data set and requested various randomly selected files.</p>
<p>Figure 10 shows the Steelhead EX + Granite Blockstore Metrics report, which measures the amount of “hits” (requested blocks that were already available at the branch) and “misses” (blocks that needed to be sent from the data center) in megabytes. This, in effect, measures the effectiveness of the Granite technology to pre-fetch and/or quickly transmit the necessary blocks, such that the branch server experiences the storage as though it is local.</p>

ESG Lab used AutoCAD software to open a 33.5 MB file (cifs.dwg). The first time the file was accessed across the WAN, the file-open process took 27.7 seconds. The file was closed and the workstation was rebooted to clear client cache. When the workstation was restarted, the same file was opened using AutoCAD, and the file opened in 5 seconds, the same as baseline testing over the LAN.</p>
<p>While Figure 10 shows the Granite technology’s effectiveness in pulling data from the data center to the branch, Figure 11 shows the behavior of data written at the branch being committed to the data center.</p>

Overall, ESG Lab found the Riverbed Granite extended storage solution to be surprisingly easy to configure and utilize. Neither the production server at the remote site nor the data center SAN felt any impact from the extended distance. The iSCSI implementation was intuitive and performed well over a simulated 3,000-mile WAN connection. The combination of Granite with Steelhead technology dramatically accelerated data transfers over low-bandwidth, high-latency connections.</p>

<h1>Why This Matters</h1>
<p>While ESG research<a href="#_ftn4">[4]</a> shows that more than 84% of infrastructure purchase decisions are made at   corporate, the implementations are often done as near-standalone   configurations per branch office. While consolidated storage at the data center   has always been regarded as a powerful method to reduce costs and management   complexity, branch offices with applications requiring local block storage   performance have had to rely on traditional direct-attached storage deployed   with local server platforms. Granite’s ability to extend iSCSI LUNs from a   data center SAN to a remote office opens up data center cost and manageability   benefits to remote sites.</p>
<p>In hands-on testing, ESG Lab found   performance over a simulated transcontinental WAN link to be remarkably   viable, demonstrating performance that rivaled local attached storage in both   throughput and latency.</td>

<h2>Remote Office Scenarios and Implications</h2>
<p>After the servers were virtualized and the SAN storage was extended from the central data center, ESG Lab was ready to explore the performance and resilience of a Riverbed-enhanced remote office when a WAN link goes down and is restored.</p>
<h3>ESG Lab Testing</h3>
<p>First, ESG Lab set a baseline by opening several large files that resided on an extended iSCSI SAN volume shared on the remote office LAN by a virtual server hosted in the Steelhead EX + Granite appliance without Granite acceleration. ESG Lab opened a 39.4 MB AutoCAD file named “http.dwg” using a client on the remote office LAN. Without Steelhead and Granite optimization, the file opened in 721 seconds, or just over 12 minutes. The AutoCAD application was completely unresponsive while the file was pulled across the WAN.</p>
<p>Next, the same file-open test was performed with Steelhead WAN optimization and Granite active. The first time the file was accessed, the operation completed in 39.1 seconds. After closing the file and opening it a second time, the file opened in 5.0 seconds. As expected, the second open was much faster, being serviced by the blockstore cache on the Steelhead EX + Granite appliance. Saving the file to a new name took 3.1 seconds.</p>
<p>As seen in Figure 12, at 18:07, ESG Lab disconnected the simulated WAN between the remote office and data center, and attempted to open the same file. The file opened successfully, in 5.6 seconds. Next, the file was saved to a new name, which completed in 3.1 seconds. This is comparable to the performance observed when the WAN was connected.</p>
<p>ESG Lab repeated these procedures multiple times, opening files and saving them to new names. Performance was consistent. Figure 12 shows the data writes/commits report from the Steelhead EX appliance.</p>
<div class="graph_top">Figure 12. Data Writes and Commits, WAN   Disconnected</div>
<p><img class="alignnone size-full wp-image-28304" title="RiverbedSteelheadEXf12" src="http://www.enterprisestrategygroup.com/media/wordpress/2012/02/RiverbedSteelheadEXf12.png" alt="" width="641" height="300" /><br />
As shown in Figure 12, as data was written to the network share, the uncommitted bytes that had been accepted by the Steelhead appliance but not yet transmitted to the data center increased. Note that the entire time that the volume was disconnected, the client and server at the remote site remained connected, and the volume remained online.</p>
<p>After approximately 30 minutes, more than 40 MB had been written to the shared volume. ESG Lab then reconnected the WAN and monitored the data writes/commits report. As can be seen in Figure 13, the Steelhead appliance committed the 43.6 MB of data to the NetApp FAS in the data center in about 45 seconds.</p>
<div class="graph_top">Figure 13. Data Writes and Commits, WAN Reconnected</div>
<p><img class="alignnone size-full wp-image-28305" title="RiverbedSteelheadEXf13" src="http://www.enterprisestrategygroup.com/media/wordpress/2012/02/RiverbedSteelheadEXf13.png" alt="" width="645" height="295" /><br />
The resynchronization was automatic and completely transparent. Users and applications saw no change in connectivity or access when the WAN link was down, nor when it came back up. Figure 14 shows a network traffic summary report for the time period that the resynchronization was executing.</p>
<div class="graph_top">Figure 14. Optimized Traffic After WAN Reconnect</div>
<p><img class="alignnone size-full wp-image-28306" title="RiverbedSteelheadEXf14" src="http://www.enterprisestrategygroup.com/media/wordpress/2012/02/RiverbedSteelheadEXf14.png" alt="" width="634" height="408" /><br />
The port number indicates the type of traffic: Port 7951 is traffic flowing between the Steelhead EX + Granite edge device and Steelhead and Granite core devices in the data center. The actual data transmitted across the WAN link was highly optimized, and, of the 43.9 MB of iSCSI data transmitted by the virtual server, only 3 MB was actually transmitted across the WAN, a reduction of 93%.</p>

<h1>Why This Matters</h1>
<p>ESG Research indicates that improving   application performance and improving accessibility for end-users are the top-two IT   priorities with respect to remote and branch offices.<a href="#_ftn5">[5]</a></p>
<p>ESG Lab validated that Steelhead EX +   Granite improved performance by a factor of 18 to 26 times when opening and   editing large CAD files across a high-latency, low-bandwidth T1 link,   providing WAN access to centralized project files at LAN-like speeds. If an   engineer has to open and edit just five of these drawings per day, this would   equate to an hour per day of reclaimed productivity (if they could even open   the file at all without the Riverbed solution), while reducing the risk of   business interruption and data loss due to connectivity issues at a remote   office. Steelhead EX + Granite demonstrated the ability to provide   uninterrupted operations for remote users with data housed in a central data   center, whether the WAN was up or down, with excellent performance.</td>

<h2>Data Protection Scenarios and Implications</h2>
<p>When extending storage from the data center to the remote office, data protection becomes multifaceted, incorporating not only backup and recovery of production data, but also protection of remote office data from loss or theft.</p>
<h3>Securing Data in the Appliance</h3>
<p>Riverbed appliances utilize integrated storage to hold cached data in remote locations, designed to enhance the remote user’s experience by providing local access to frequently used data. The Riverbed Steelhead + Granite appliance offers AES encryption (up to and including AES-256) to securely encrypt the data on disk. The AES key for the Granite blockstore is kept in a secure vault area, which is also encrypted using AES-256.</p>
<p>The default key to each appliance vault is unique, derived from a unique identifier of each appliance. The vault key can be changed by organizations to comply with their own security standards. When an appliance boots, the vault key must be provided, or the contents of the blockstore are not accessible. A visual representation of Riverbed encryption is shown in Figure 15.</p>
<div class="graph_top">Figure 15. Data   Encryption in Steelhead and Granite</div>
<p><img class="alignnone size-full wp-image-28307" title="RiverbedSteelheadEXf15" src="http://www.enterprisestrategygroup.com/media/wordpress/2012/02/RiverbedSteelheadEXf15.png" alt="" width="654" height="261" /></p>
<h3>Backup and Recovery</h3>
<p>When considering backup and recovery, multiple data protection scenarios are either enabled or enhanced, including:</p>
<ul>
<li>File/application-based protection of the remote data, from the data center</li>
<li>Block-based protection of the LUNs used by the branch platforms, from the data center</li>
</ul>
<p>In principle, because server-centric storage utilized at the branch is in fact extended from the data center via Granite (and user-centric data from the branch is stored locally on Granite-extended volumes), Riverbed suggests that data protection can be done entirely from the data center instance of the data.</p>
<p>ESG Lab audited the operating methods that Riverbed uses for storing its data to understand the viability for customers to use their current data-protection methods within a Steelhead EX + Granite deployed configuration.</p>
<h3>Traditional File/Application Backups from Guest-VM Branch Servers</h3>
<p>For production servers running at the branch, presumably as virtual machines within the Steelhead EX + Granite (VMware Virtual Server) host environment, traditional file- and/or application-centric backups are still achievable.</p>
<p>ESG Lab looked at how a typical backup agent can be installed within a virtualized production OS to send backup data to the requesting backup server located at the data center, as shown in Figure 16. In this configuration, as files are queued to be sent from the production VM to the backup server, Steelhead WAN optimization is designed to recognize the data that already exists at the data center from previous synchronizations. In this case, while both the remote backup agent and the data center backup server believe that the data is being sent across the WAN, only truly unique data segments and reference “pointers” to previously encountered data actually traverse the network.</p>
<div class="graph_top">Figure 16. Traditional   File/Application Backups from Guest-VM Branch Servers</div>
<p><img class="alignnone size-full wp-image-28308" title="RiverbedSteelheadEXf16" src="http://www.enterprisestrategygroup.com/media/wordpress/2012/02/RiverbedSteelheadEXf16.png" alt="" width="652" height="236" /><br />
Based on how ESG Lab tested file transfers with Steelhead EX + Granite, file-centric data movement during backups should be nearly eliminated. Similarly, application-centric backups that generate storage IO as part of the backup process (such as SQL Server log files) will benefit. In those cases, as the data files are prepared for backup, their corresponding blocks within Granite will be committed to the data center and therefore may not need to traverse the WAN during the actual backup.</p>
<h3>SAN-based Backup of the Branch from the Data Center</h3>
<p>Perhaps the most intuitive and yet subtle method ESG Lab observed was the ability to back up the extended LUN from within the data center. Because the SAN is unaware of the Steelhead/Granite solution, LUNs can be backed up directly using storage-based snapshots and clones—traditional “serverless” backup solutions.</p>
<p>As seen in Figure 17, ESG Lab observed that by backing up the original LUNs from the SAN, all of the production data could be protected in the data center, including virtualized server-centric data and client-specific data that are Granite-extended.</p>
<div class="graph_top">Figure 17. SAN-based Backup of the Branch LUNs from   the Data Center</div>
<p><img class="alignnone size-full wp-image-28309" title="RiverbedSteelheadEXf17" src="http://www.enterprisestrategygroup.com/media/wordpress/2012/02/RiverbedSteelheadEXf17.png" alt="" width="650" height="223" /><br />
As shown in Figure 17, ESG Lab found serverless backups of remote office volumes to be potentially ideal choices for those customers who already utilize them within their data centers. The IO burden is removed not only from the production resources, but also from the Steelhead and Granite appliances, freeing them up for production IO exclusively. Like any serverless backup, an understanding of the applications in use and the need for consistency and post-backup processing are keys to success.</p>
<h3>Riverbed SAN Hardware Snapshot Integration</h3>
<p>Along with extending and potentially enhancing customers’ existing backup methodologies, Riverbed has also developed a Riverbed Hardware Snapshot Provider (RHSP) mechanism to directly integrate its storage-extending capabilities with both the Microsoft Volume Shadow Copy Service (VSS) and SAN arrays from EMC, Dell EqualLogic, and NetApp.</p>
<p>Although RHSP was not tested by ESG Lab, a discussion with Riverbed highlighted RHSP capabilities that directly address the need for application consistency with backup. RHSP installs as a plug-in on Windows clients in the branch office. It is used within the VSS process to place a point-in-time marker into the Granite blockstore. This enables a backup agent to quiesce an application to indicate an application-consistent restore point. In turn, this indicator triggers a snapshot on the data center SAN storage array that can then be used for any required restores or subsequent secondary backups to disk or tape in the data center.</p>

<tr>
<td width="706" valign="top">
<h1>Why   This Matters</h1>
<p>ESG research<a href="#_ftn6">[6]</a> shows that 71% of remote office locations   still perform local backups, even though the vast majority of companies that   have spoken with ESG say they would prefer to centrally manage and secure   their data. By extending the storage from datasets that coexist within the   data center, Riverbed customers can secure branch data and may very well find   that they can achieve their goal of “centralized backup” by backing up from the   data center instance of the branch data.</p>
<p>Whether an IT   department prefers guest-based or SAN-based backups, the Granite solution illustrates   the viability of protecting branch data from the data center and provides new   backup flexibility in situations where decentralized backups may have been   presumed to be the only option. Based on ESG Lab findings, customers using   SAN‑centric backup solutions (e.g., snapshots) should be especially pleased   to discover that they can use these same methods for protecting branch data and   for protecting their data center volumes, because all of the LUNs are now in   the same place.</td>

<h1>ESG Lab Validation Highlights</h1>
<ul>
<li>ESG Lab used Steelhead appliances to optimize WAN performance and reduced data by up to 50 times, enabling more productive collaboration between remote and central offices.</li>
<li>When running an OLTP database workload in a Riverbed appliance-hosted virtual machine, ESG Lab observed latency to storage over the WAN decreased by more than 67%, enabling a remote server to mount an iSCSI volume hosted in a distant data center, and making it possible to consolidate business-critical branch services over the WAN.</li>
<li>ESG Lab found Granite-extended block-storage performance over a simulated transcontinental WAN link to be remarkably viable, rivaling local-attached storage in both throughput and latency.</li>
<li>ESG Lab validated that Riverbed improved performance by a factor of 18 to 26 times when opening and editing large CAD files across a high-latency, low-bandwidth T1 link, providing WAN access to centralized project files at LAN-like speeds.</li>
<li>ESG found that customers’ existing backup methodologies were all potentially viable options for remote offices—in ways not achievable without the combination of WAN optimization and storage extension. Without changing their backup mechanisms, customers may find their solutions enhanced because of how Steelhead optimizes the data streams that Granite has already synchronized between sites.</li>
</ul>
<h1>Issues to Consider</h1>
<ul>
<li>It should be noted that one key to the performance of the extended storage is the built-in blockstore within the Steelhead EX + Granite appliance itself. When designing the storage to be used at the branch, customers should be aware that the Granite solution does not change normal design considerations around capacity or IO performance. Those aspects should still be considered when determining the size of the Granite edge device to place at a particular branch location.</li>
<li>While many data-protection scenarios are enhanced through this configuration, for SAN-based backup of the branch from the data center, a minimal amount of effort is still required to ensure the boot volumes of the virtualized VMs on VSP within each branch appliance are protected and recoverable. ESG Lab hopes that Riverbed will address this in future releases, so that even in the VSP scenario, an entire VM can be protected at the data center.</li>
<li>While many backup processes may potentially gain benefit from a Riverbed Steelhead solution with Granite technology, they do so without any awareness of Riverbed’s changes to infrastructure or topology.</li>
</ul>
<p><strong><br />
</strong></p>
<h1>The Bigger Truth</h1>
<p>Riverbed provides comprehensive WAN optimization solutions, helping organizations share applications and data across global wide-area networks. Riverbed WAN optimization solutions have been proven in the field to give businesses order-of-magnitude increases in the performance and value of their existing IT infrastructure and mission-critical applications, including file sharing, e-mail, backup, document management systems, IT tools, and ERP and CRM solutions.</p>
<p>Riverbed has applied its field-proven WAN optimization technology to provide similar performance gains for SAN-based block data extended to remote offices. Achieving a data reduction of more than 26 to 1 in ESG Lab testing, Steelhead Granite technology not only reduces the amount of bandwidth needed to connect to data center SAN storage, but also provides access to remote users at local speeds, maximizing the productivity of those remote workers. Steelhead EX + Granite also enables organizations to utilize existing investments in data protection hardware and software and secures that data in the data center.</p>
<p>In a truly fluid enterprise, all data and storage resources will be centralized in the data center. When that occurs, organizations will gain the ability to provide desired performance in the branch and the ability to quickly provision systems and storage wherever or whenever they wish. In addition, data protection becomes much easier and more secure for remote offices—it is executed centrally along with all valuable corporate data in the data center.</p>
<p>ESG Lab confirmed, through hands-on testing, that Riverbed’s Steelhead EX + Granite solution is able to reduce remote office network traffic while extending data center SANs with little impact on remote office servers and clients. The solution integrated well with Microsoft Exchange and SharePoint business applications as well as basic file system services and iSCSI block storage, long considered all but impossible to extend over long-distance, low-bandwidth WAN links. Organizations interested in improving the remote user experience while bringing data-center-class performance and protection to their remote offices should seriously consider Riverbed Steelhead EX + Granite.</p>

			<content:encoded><![CDATA[<p><a href="http://www.ibm.com/" target="_blank">IBM</a> announced today (January 31, 2012) its intent to purchase privately held <a href="http://www.worklight.com/" target="_blank">Worklight</a>. Headquartered in Tel Aviv, Israel, and New York, New York, Worklight markets software and systems for developing and deploying mobile applications. They support all the major mobile platforms &#8211; iOS, Android, Windows Mobile, and BlackBerry -natively. Worklight also supports HTML5 which is quickly becoming the language of choice for creating applications that have to run on multiple endpoint platforms. More than just a developer’s toolkit, Worklight also has server technology that helps connect mobile applications to enterprise application servers, including IBM’s, WebSphere Application Server.</p>
<p>The most basic purpose of the social enterprise is to achieve business goals through enhanced interactions. The ability to connect to others in the company, partners, and customers no matter where they are or what type of device they use is critical to realizing the benefits of social enterprise applications. It’s hard to be social when you can’t participate. Because of this, the social enterprise is tightly intertwined with mobile endpoints. The ability to deliver an application anytime and anywhere someone needs it is key part of making it social. Mobile cannot be an add-on to the social strategy. It has to be a critical component.</p>
<p>Part of the rationale behind this IBM move is to help IT deal with the influx of consumer devices by helping IT design applications that work on a variety of platforms, especially mobile endpoints. That makes sense given the growth in consumer devices that have been introduced into previously closed environments. In the ESG Research Brief, <a href="http://www.enterprisestrategygroup.com/2011/05/esg-research-brief-corporate-endpoint-device-type-trends/" target="_blank"><em>Corporate Endpoint Device Type Trends</em></a>. published in May of 2011, ESG found <em>that 95% of IT organizations surveyed were experiencing growth in the use of alternative endpoints</em>. IT professionals know they can’t stem the tide of consumerization and IBM is helping them deal with it by bringing Worklight into their portfolio.</p>
<p>This acquisition dovetails nicely into other IBM social products such as IBM Connections – IBM’s social communications software &#8211; and IBM Endpoint Manager for Mobile Devices (GA planned for March 2012), which provide security for endpoint devices including mobile platforms. Worklight also enhances and extends IBM’s social enterprise development environment. IBM now has one of the most comprehensive frameworks for developing mobile, cloud, and social enterprise applications. Coupled with their traditional enterprise development tools such as IBM Rational and IBM Lotus Notes, IBM offers a compelling suite of products for creating scalable and robust enterprise applications.</p>
<p>With Worklight, IBM customers and partners will be able to develop and deploy socially enabled applications more quickly no matter where the user is or what endpoint platform they use.</p>

			<content:encoded><![CDATA[<p>As organizations continue to consolidate data centers and increase their use of server virtualization technology, IT departments are forced to respond by building out massively scalable data center network environments. However, are data center networks evolving fast enough to survive (in current form) in a rapidly changing world?  Jon Oltsik called this problem <a href="http://www.insecureaboutsecurity.com/2012/01/11/data-center-networking-discontinuity/" target="_blank">Data Center Network Discontinuity </a> and data from the forthcoming ESG’s 2012 IT Spending Intentions survey (which I’ve gotten a preview of) indicates that we may be starting to see the first signs of this occurring.</p>
<p>Although most overall IT budgets are edging up slightly, network budget growth is much more robust. Almost 60% of respondents (58%) report that they will be increasing their network budgets in 2012. The larger the organization(enterprises with 1,000 or more employees), the greater the increase. In fact, 21% of enterprises expect to increase spend by 8% or more.</p>
<p>Where will this money be spent? According to our research it will be spent on:</p>
<ul>
<li>Network security. As the network environments scale, organizations will require their security services to scale with them and be more tightly integrated with the network. For more on security spending see Jon Oltsik’s <a href="http://www.insecureaboutsecurity.com/2012/01/24/information-security-budgets-will-increase-in-2012/" target="_blank">security blog</a>.</li>
<li>Network management. The key to managing more with less will be better network management tools. However, with only so many span ports to connect to, organizations will need to find solutions to help them scale their network management/monitoring coverage for the whole environment. This could bode well for companies like Anue, Gigamon, Netoptics, and VSS that will be instrumental in providing visibility across massively scalable networks. Especially for those 10 GbE networks. This management at scale may also open the door for SDN/OpenFlow vendors to highlight the virtues of their solutions.</li>
<li>WAN optimization. It’s not just for the troublesome remote office anymore. As organizations continue to consolidate data centers, connect to cloud and SaaS providers, and try to deliver a solid user experience for  remote workers, we expect more organizations will be taking an enterprise wide approach  to optimizing their connections. Especially as latency sensitive applications like video, desktop virtualization and VoIP (see next bullet) continue to proliferate in the data center. Established WAN optimization vendors like Blue Coat, Cisco, Citrix, Riverbed, SilverPeak, and others have already started to adapt their solutions to meet these emerging needs.</li>
<li>VoIP. One third of the respondents indicated that they would make investments in VoIP solutions. With a rapidly changing and increasingly remote workforce, VoIP solutions provide greater flexibility options. As networks continue to converge, we expect this will also include video and even desktop virtualization as well. So organizations would do well to look for both solutions.</li>
<li>Headcount. ESG found that 36% of organizations plan to hire additional network staff – fortunately, most believe there are plenty to be found. The only area that showed a higher increase in adding more people was security.</li>
</ul>

			<content:encoded><![CDATA[<p>IBM and NEC announced this week that the two companies will work together to  offer networking solutions based upon SDN and OpenFlow. IBM provides the  switches which are integrated with the NEC Programmable Flow Controller.</p>
<p>To me, this is bigger than just a press release and some joint marketing  programs. Here’s why:</p>
<ol>
<li>IBM and NEC are moving OpenFlow beyond academic labs and cloud computing  theory, taking their joint solution to enterprise data centers. Yes, enterprises  need to be educated on SDN and its benefits, but the use case for OpenFlow is  certainly there since legacy networks can’t keep up with growing data scale or  virtual server mobility.</li>
<li>While the headline may be OpenFlow, it’s really all about software.  Mainframes became virtual computing platforms in the 1970s and Intel servers did  the same with server virtualization technology from Citrix, Microsoft, Red Hat,  and VMware. The next step is cloud computing which is intended to virtualize the  whole IT infrastructure enchilada but static proprietary networks just don’t  play well in this arena.</li>
<li>You have to give NEC credit for recognizing the software-centric opportunity  around OpenFlow and bringing a quality controller to market. NEC could become  the standard glue of a heterogeneous OpenFlow network over time.</li>
<li>When HP purchased 3Com, a lot of people had IBM reacting with an acquisition  of Brocade or Juniper. With SDN/OpenFlow, IBM can create a data center fabric  out of access switches. Between OpenFlow and existing partnerships, I can’t see  IBM making a big networking acquisition anytime soon.</li>
<li>For those of us who’ve been around the industry for a while, it is certainly  ironic to see IBM taking a leadership position in networking. I know I’m showing  my age, but it doesn’t seem like that long ago that IBM was pushing Token Ring  and SNA.</li>
<li>Personally, I don’t see SDN and OpenFlow as a threat to Cisco. In fact,  Cisco could build OpenFlow software with IOS/Nexus intelligence and integration  as sort of a dual path strategy. If I’ve learned anything about the network  industry it is this: Never (and I mean never) count Cisco out when it comes to  networking.</li>
</ol>
