Introduction Rapid file storage growth, driven by rich media, documents, backup files and email, impacts businesses more now than ever before. Consolidating file data with a dedicated NAS solution can help address any data center s file serving needs, while reducing the cost of ownership by enabling simplified management, better resource utilization, centralized growth and data protection. NAS is file-level computer data storage connected to a computer network providing data access to heterogeneous clients. As of 2010, NAS devices continued to gain popularity, offering a convenient method of sharing files between multiple computers. NAS appliances are offered by a number of vendors, yet few publish benchmark results until now. HP, working closely with Microsoft and Emulex, decided to take their appliance into their benchmark lab. The end result is a proven solutions-based, reference architecture for large data centers requiring a scalable storage solution that can support over 26 thousand users. This white paper provides the following benchmark testing results, using File Server Capacity Tool (FSCT): n HP StorageWorks X3800 G2 Network Storage Gateway with Windows Storage Server 2008 R2 Enterprise Edition and Emulex connectivity components across Fibre Channel and 10GbE n HP StorageWorks X1800 G2 Network Storage System with Windows Storage Server 2008 R2 and connectivity components across 1GbE The test results provided in this white paper were generated by Hewlett Packard using the Microsoft File Server Capacity Tool.

Even post- and pre-transport operations are improved, providing improved flexibility and more compatibility with today s file service technologies. n Optimized File Services: Registry level file and print optimization entries have been configured by Microsoft experts to make Windows Storage Server a more effective file server. This reduces (or removes) several other services, creating less administrative overhead because fewer updates/patches are required. n SIS improvements: SIS adds cluster support, as well as performance gains. SIS searches for files that are identical on the NTFS file system volume, and then reports those files to the SIS filter driver. Most of the work is done when the operating system is not busy (in background mode), so that file serving performance impact is reduced. n Support for Microsoft Bitlocker Drive Encryption: Provides enhanced protection against data theft and exposure of server hardware if lost or stolen, and it provides more secure data deletion. The Enterprise edition of Windows Storage Server 2008 R2 (installed on all HP StorageWorks X3000 Network Storage System models) also includes a MSCS license. File Server Capacity Tool File Server Capacity Tool 1.0 (FSCT 1.0) helps estimate the maximum number of users that server hardware can support under a specific workload, and it can help you understand when and where bottlenecks occur. To download this tool, see File Server Capacity Tool in the Microsoft Download Center. A step-by-step guide is available in the download package, which provides detailed instructions about installing, running, and reviewing FSCT test results. FSCT was created by Microsoft after analyzing the workload of production file servers used to store user s home folders. The tool simulates a typical file server s workload in a lab environment. Figure 1 shows the components of FSCT. It is a tool for CIFS/SMB/SMB2 file servers focused on capacity planning and is also useful for identifying bottlenecks. FSCT can simulate multiple TCP connections and sessions, with each client test machine simulating multiple users. It can also exercise certain sequences of file operations to simulate real application behavior. 6

Figure 1 FSCT components. FSCT measures the throughput capacity of a file server either as the maximum number of operations per second or as a maximum number of users supported by the configuration. These values are influenced by several factors, some of which include processor speed, available memory, disk speed, network throughput and latency and the speed with which SMB requests are processed. FSCT Performance Testing with HP StorageWorks X3800 G2 Network Storage Gateway and HP StorageWorks X1800 G2 Network Storage System Objective The objective for the performance testing was to: n Determine the number of users the HP StorageWorks X1800 G2 Network Storage System and HP StorageWorks X3800 G2 Network Storage Gateway can support in an as shipped configuration. n Determine the number of users the systems can support with minor operating system customizations. n Determine the number of users the systems can support with minor hardware upgrades (i.e., increase memory). 7

To meet these testing objectives, a set of workload tests was conducted as described below. Reference Architecture Configurations The test configuration consisted of an HP server and NAS appliance, as well as peripheral components to connect the configuration to a network. Each test server had three different testing scenarios: n As-shipped configuration (no hardware changes, no operating system customizations) n Operating system customizations (no hardware changes, operating system customizations implemented) n Minor hardware customizations (hardware changes to memory, operating system customizations implemented) The HP StorageWorks X1800 G2 testing server used Windows Storage Server 2008 R2 Standard Edition, while the X3800 G2 testing server used Windows Storage Server 2008 R2 Enterprise Edition. Each server ran the FSCT tool for preparation and configuration of the benchmark test files/folders. HP StorageWorks X3800 G2 Configuration This reference architecture connects to a 10GbE network with 8Gb/s Fibre Channel for storage (see Figure 2). Figure 2 HP StorageWorks X3800 G2 benchmark configuration. 8

HP StorageWorks X3800 G2 Testing Server The HP StorageWorks X3800 G2 Network Storage Gateway server was configured with two Intel Xeon six-core X5650 series processors and 72GB memory. The HP StorageWorks X3800 G2 server used the Windows Server 2008 R2 Enterprise Edition operating system. The testing server also ran the FSCT software for preparation of the testing files and folders. The testing server was connected to the SAN with the HP-branded Emulex 8Gb/s Fibre Channel HBA and to the clients with the HP-branded Emulex 10GbE UCNA. Storage Subsystem The HP P2000 G3 MSA Array was configured as the SAN storage array and both ports from two storage processors SPA and SPB were connected to the host via an 8Gb/s Fibre Channel switch. A total of ninety-six (96) 72GB 15K Fibre Channel drives were configured into 8 RAID 10 LUN groups of 12 drives. The HP StorageWorks X3800 G2 was configured with MPIO enabled to allow for multiple connections to the P2000 G3 storage arrays. Along with enabling MPIO for the multiple data paths, Microsoft best practices were enabled to help enhance the performance and provide consistent and re-certifiable results. Adapters The HP-branded Emulex 8Gb/s Fibre Channel HBA model used in the configuration was the dual-channel LPe12002 (HP part number AJ763A). Both ports of the four adapters were attached to the SAN and all 8 LUNs were presented to both ports. The HP-branded Emulex 10GbE UCNA model used in the configuration was the OneConnect OCe10102-F (HP part number NC550SFP). The card was set to a static IP address through the 10Gb/s switch and all clients were configured to use the static IP of the server for the tests. HP StorageWorks X1800 G2 Configuration This reference architecture connects to a 1GbE network (see Figure 3). Figure 3 HP StorageWorks X1800 G2 benchmark configuration. 9

HP StorageWorks X1800 G2 Testing Server The HP StorageWorks X1800 G2 Network Storage System server was configured with one Intel Xeon X5640 series processor and 6GB memory. The HP StorageWorks X1800 G2 server used the Windows Storage Server 2008 R2 operating system. The testing server also ran the FSCT software for preparation of the testing files and folders. Methodology For the tests, FSCT was set to calculate the maximum user count that could be provided by each system in the three different testing scenarios. Each system was run with a similar command argument to produce similar output as described below. Preparation Client: fsct prepare client /controller PerfController /server <HP X1000 G2 Server Name> /password <password> Server: fsct prepare server /clients <perfclient1, perfclient2 perfclient N> /password <password> /users 1000 /volumes <volume on server : > /workload HomeFolders /verbose verbose Execution Client: fsct run client /controller PerfController /server <name of server> /password <password> /domain <domain> Controller: fsct run controller /server <name of server> /password <password> /volumes <volume on server : > /clients <perfclient1, perfclient2 perfclient N> /min_users 1000 /max_users 8000 /step 200 /duration 720 /workload HomeFolders FSCT Performance Test Results The benchmark test results for the HP StorageWorks X3800 G2 Network Storage Gateway and the HP StorageWorks X1800 G2 Network Storage System are provided below. The main benchmark shows the scenario throughput, defined as follows: Scenario throughput The number of scenarios executed per second. Scenario throughput is the number of file handling operations per second possible in a given client/server configuration. FSCT 1.0 includes a single workload folder (HomeFolders) which simulates a standard user s workload based on Microsoft Office, Windows Explorer and command-line usage when the user s home directory is located on the file server. FSCT Results for HP StorageWorks X3800 G2 The FSCT test results for the HP StorageWorks X3800 G2 Network Storage Gateway are summarized below in Figure 4.

The testing shows the HP StorageWorks X1800 G2 Network Storage System can support the needs of small data centers who are planning for growth and those of midsize data centers. With minor OS modifications, the performance improves with this scalable solution. Note that with additional disks, it is likely that higher performance and scalability can be achieved, but Table 2 provides the results of actual tests completed. Test Guidelines As you complete your analysis, the following are guidelines that can be used to determine if a server can support your needs: 4000 users maximum per 1Gb NIC A 1Gb NIC is required for every 4000 user increment. Adding more 1Gb NICs or adding a 10Gb NIC can alleviate this issue. >110,000,000 bytes/sec (Disk Read + Disk Write) = 1Gb NIC bottleneck If running tests and memory is not an issue, you may experience a NIC bottleneck where the number of disk writes plus disk reads is greater than 110,000,000 bytes/sec. Adding more NICs can alleviate this issue. >60% CPU utilization can affect performance If the CPU utilization is greater than 60%, upgrading to a faster CPU or adding a secondary CPU can improve performance. Conclusion The tested configuration of the HP StorageWorks X3800 G2 Network Storage Gateway running Windows Storage Server 2008 R2 using HP-branded Emulex LightPulse LPe-12002 8Gb/s Fibre Channel HBAs and OneConnect OCe10102 UCNAs provides a robust, scalable, high performance storage solution for large data centers.
