3 Introduction The technical report TR-949: NetApp and VMware View 5,000-Seat Performance Report examined a number of different common virtual desktop infrastructure (VDI) scenarios from the perspective of the fictitious Acme Corporation. It is now 0, and Acme Corporation has expanded its operation across the country, opening a small and medium business office (call center/training facility) in the southeast corridor. Acme Corp s executives have two concerns for this remote facility, namely, cost performance and future expansion. Customers require innovative end-to-end storage solutions that can simplify the architecture in a costeffective manner and provide the maximum uptime. NetApp clustered Data ONTAP, with its key capabilities such as nondisruptive operations, unified storage, multiprotocol architecture, secure multitenancy, storage efficiency, read and write performance, and cost-efficient data protection, is ideal for cost-efficiently designing and deploying an end-to-end storage solution. Whether the customer is a large enterprise in need of multiple pods of desktops or a small to medium business for which cost density is a primary driver, NetApp offers an effective and compelling solution. For a small to medium business, the FAS40- platform offers a good starting point configuration. Midsized businesses and enterprises with distributed environments need powerful, flexible data storage to handle data growth. The NetApp FAS00 series, named a Champion and Best in Overall Value by Info-Tech Research Group, is affordable and is a more powerful storage platform than other systems in its class. Protect your storage investment with systems that grow with your business needs: Get a truly unified storage architecture. Expand to more nodes with clustered Data ONTAP quickly and easily without disruption as your needs grow. Seamlessly upgrade to other NetApp systems while using the same operating system and software tools. Get built-in investment protection with the ability to convert your FAS40 system to an external disk shelf for upgrading to larger NetApp systems. The following list provides the design details of the floating desktop deployment scenario, offering a very compelling $5 storage cost per desktop (considering standard discounts). This storage configuration allows hosting 800 users in a two-rack unit (U) NetApp FAS40- storage system. You can scale to thousands of desktops at the same $5 storage cost per desktop by adding more U NetApp 40- storage systems to the environment. The $5 storage cost per desktop includes: NetApp hardware: FAS40- HA with 4 internal drives (600GB SAS, 0K RPM) NetApp software: NFS, CIFS, FC, iscsi (storage protocols). Our test configuration setup used NFS; however, CIFS, FC, and iscsi protocol licenses are also included at no additional cost. Support and services: 6 months, 4/7, 4-hour parts replacement, and initial installation Defined in NetApp TR-949: NetApp and VMware View 5,000-Seat Performance Report as modular units of 5,000 seats.

4 At just $5 per desktop, the FAS40- is compelling in terms of cost density, answering Acme Corp s first concern. The NetApp clustered Data ONTAP architecture provides the rest. The rest of this paper documents the tests performed to validate the $5 per desktop claim. $5 per desktop is based on 800 Windows 7 virtual desktops running Login VSI 4.0. medium workload generating IOPS per desktop. VMware View 5. SE sparse disks were used with the linked clone provisioning method. The configuration described is a floating desktop configuration in which in all users log in for the first time Monday morning, and all desktops are refreshed each weekend. For details about the configuration used, refer to section, Configuration. Actual customer results may vary. 4 VMware Horizon View 5. on NetApp Clustered Data ONTAP at $5/Desktop

The active-passive configuration provides the best failover scenario, as well as the largest number of data drives without expanding to an external shelf. Testing validated that 4 600GB SAS drives housed within the U FAS40- chassis were sufficient in terms of both IOPS and density for up to 800 nonpersistent 4 virtual desktops; therefore no external shelves were necessary 5.

6 For density calculations, this paper considered 6GB of unique data representative of reality for floating desktops. Customer interviews generally indicated 5GB as standard; thus, 6GB represented an additional 0% for scaling purposes. VMware s documentation suggests the following formula for capacity needs 6 : ( ( )) ( ) For this paper we used, we used the following calculation: (800 * (5% * 4GB) + GB)) + (* 4GB) Memory per Virtual Machine Capacity Needed Prior to Deduplication Aggregate Space Utilization GB 5,648GB 7%.5GB 6,048GB 76% GB 6,448GB 8% All virtual desktops were composed as VMware View Composer SE sparse linked clones with floating user assignment using the latest available releases of VMware vsphere 7 and VMware Horizon View 8. The datastores were NFSv accessed over a single 0GbE link to the active controller. Jumbo frames were configured and flow control disabled. NetApp makes no claims in this paper about the recommended server count or model; the configuration described in the rest of this document is for documentation purposes only. Performance Test Tool Login VSI was used as a workload generator to simulate a multiuser workload and to size for server capacity in VDI environments. Login VSI is a collection of scripts and automation tools that utilizes real user-space applications to generate its workload. These applications include Microsoft Word, Excel, Outlook, and web browsing along with various freeware tools, including a PDF printer and flash video. Random data is generated in each application, and reads, edits, and saves are all performed. For more information about Login VSI, go to Performance Test Plan The tests were designed to simulate a customer environment running typical application workloads. Testing was not done to demonstrate the maximum achievable throughput of the storage array. Scale testing of up to 800 seats for boot storm, login storm, and steady states was performed. For each test, Login VSI medium workload was used. Because the desktop implementation of interest is floating rather than persistent, this paper focuses on the initial login rather than steady state. An initial login is one in which the users log in for the first time and begin working. This login triggers profile creation and is an intensive workload on the storage due to application binaries, DLLs, and other data being loaded for the first time DA9-94C-FBF77EE.html#GU-0B506F-40E-4DA9-94C-FBF77EE 7 ESXi VMware Horizon View 5..0 and VMware View Composer VMware Horizon View 5. on NetApp Clustered Data ONTAP at $5/Desktop

7 Table ) Test plan. Workload Boot Initial login Test Cases VMware View managed the boot sequence of all 800 SE sparse linked clone virtual desktops. The test assumed one user logging in and beginning work every nine seconds until the maximum of 800 users was reached, at which point steady state was assumed. Steady state With the steady state workload, all users performed various tasks using Microsoft Office, web browsing, PDF printing, playing flash videos, and using the freeware mind mapper application. For the boot storm tests, all virtual machines booted within 6 minutes. Virtual machines were considered booted as soon as VMware Tools checked in on all virtual desktops; this meant that the virtual desktops were accessible and usable.. Performance Test Results The chart in Figure shows both the total average storage processor utilization as well as average disk utilization. As all workloads presented in this paper, the results presented in the charts demonstrate the start of day, when users log into desktops for the first time. In this scenario, applications are reading libraries from disk, user profiles are being created, and the Login VSI medium workload is running. In short, this workload is the heaviest workload of the day. Figure ) Storage utilization during initial login. The chart in Figure shows the initial login times for all 800 users. Notice that with exception of a few outliers, all logins took less than 8 seconds 9. 9 The developers of Login VSI have confirmed that the left axis of this graph should be listed in terms of seconds rather than milliseconds. This is an issue with the Login VSI Analyzer. 7 VMware Horizon View 5. on NetApp Clustered Data ONTAP at $5/Desktop

8 Figure ) Login VSI login timers. The chart in Figure 4 shows the operation count and operation latency from the perspective of the storage array. The average response times at the protocol layer are all below six milliseconds. The array managed these response times with memory and 4 total hard disks. Note: No other host or storage caching technology was used. Figure 4) Protocol latency and op count. 8 VMware Horizon View 5. on NetApp Clustered Data ONTAP at $5/Desktop

9 4 Conclusion For a small to medium business, the FAS40- platform offers a good starting point configuration. Midsized businesses and enterprises with distributed environments need powerful, flexible data storage to handle data growth. The NetApp FAS00 series, named a Champion and Best in Overall Value by Info-Tech Research Group 0, is affordable and is a more powerful storage platform than other systems in its class. At just $5 per floating desktop, the FAS40- is compelling in terms of cost density. NetApp clustered Data ONTAP, with its key capabilities such as nondisruptive operations, unified storage, multiprotocol architecture, secure multi-tenancy, storage efficiency, read and write performance, and costefficient data protection, is ideal for cost-efficiently designing and deploying an end-to-end storage solution. Whether the customer is a large enterprise in need of multiple pods of desktops or a small to medium business for which cost density is a primary driver, NetApp offers an effective and compelling solution. Appendix VSImax is a metric derived by the Login VSI analyzer to determine whether the target environment has reached its saturation point and, if so, at how many concurrent sessions. As demonstrated in Figure 5, the Login VSI maximum value was not reached in the configuration presented in this paper. This metric is reserved for the appendix because its meaning is less immediately clear to a reader than those placed in the body of the paper. 0 $5 per desktop is based on 800 Windows 7 virtual desktops running Login VSI 4.0. medium workload generating IOPS per desktop.

10 Figure 5) Observe that the calculated maximum number of concurrent sessions was not reached. Drive utilization is a clearer metric in this white paper than transfers per second per data drive. With that said, the transfers/second metric is a valuable metric to track. While the 0K SAS drives are capable of executing hundreds of transfers per second, approximately 0 sustained transfers per second per drive is a reasonable transfer rate that can be expected from a properly sized configuration. Figure 6) Hard drive transfers per second. 0 VMware Horizon View 5. on NetApp Clustered Data ONTAP at $5/Desktop
