CITRIX XENAPP HOSTED SHARED DESKTOP PERFORMANCE ON CISCO UCS:
CISCO VM-FEX VS. TRADITIONAL VSWITCH
In an SBC (server-based computing) application, such as a Citrix® XenApp™
hosted shared desktop, session responsiveness is key to creating the best possible enduser experience. Under demanding network conditions, there can be many challenges
to maintaining SBC responsiveness; choosing the right technologies can make significant
steps in overcoming these challenges.
In the Principled Technologies labs, we used Login Consultants Virtual Session
Indexer (Login VSI) 3.7 benchmark to compare the responsiveness of a Citrix XenApp
hosted shared desktop farm using two switching methods: a traditional vSwitch and
Cisco Virtual Machine Fabric Extender (VM-FEX). We found that the farm using Cisco
VM-FEX provided a user experience that was up to 29 percent more responsive than the
traditional vSwitch farm. In addition, under extreme network conditions, a Cisco VMFEX-enabled virtual machine used resources more efficiently than the vSwitch-attached
virtual machine, reducing CPU utilization by as much as 53 percent.

CISCO VM-FEX CAN DRIVE DOWN LATENCY
Using PCIe pass-through technology, Cisco VM-FEX connects the Cisco Unified
Fabric directly to a virtual machine enabling VMware® DirectPath I/O. With a direct
connection to the fabric, VM-FEX decreases network latency and places the switching
load on the Cisco 1240 VIC (Virtual Interface Card), freeing compute resources on the
server. By moving compute demand off the server CPU, VM-FEX enables more resources
for applications, resulting in a more responsive application.
Figure 1 illustrates how Cisco VM-FEX PCIe Pass-Thru mode works in your
environment.
Figure 1: VM-FEX PCIe Pass-Thru mode.
We set up two Citrix XenApp hosted shared desktop farms on identical
hardware. One farm made use of a VM-FEX-enabled vSwitch and the other was on a
traditional vSwitch. We used a medium Login VSI 3.7 workload to simulate typical office
users and to compare the hosted shared desktop performance of Cisco VM-FEX versus
traditional vSwitch technology. While the Login VSI test ran, we used Iperf to simulate
additional network traffic typically found in an organization. As we increased the
number of user sessions to 140 (where we stopped because CPU percentage was mostly
saturated), we compared the user response times for both farms. As the servers added
more and more sessions, the VM-FEX solution provided a noticeable improvement in
session responsiveness.

Figure 2 shows the VSI index average for both vSwitch and VM-FEX for a fully
utilized host (75-90 percent CPU usage). While both solutions remained within an
acceptable latency range throughout our tests, as we increased the number of sessions,
the Cisco VM-FEX solution was noticeably more responsive than the traditional vSwitch
solution.

BETTER RESOURCE UTILIZATION UNDER EXTEREME LOADS
The switching method you use can affect how efficiently your server-CPU
resources are used. We used Iperf to push as much network traffic as the VM network
adapter would allow. Because VM-FEX offloads the CPU switching overhead to the Cisco
1240 VIC, it is more efficient with server CPU, as Figure 4 clearly shows.

SIMPLIFIED OPERATIONS
In addition to performance advantages, Cisco VM-FEX offers simplified, central
management capabilities within the Cisco UCS Manger. Using the Cisco UCS Manager,
we set up our VM-FEX-enabled vSwitch and completed tasks such as setting VLAN
access and MTU speeds without having to configure our hosts individually. Once we
deployed our VM-FEX-enabled vSwitch, adding a vSphere host was simple and required
very little configuration, ensuring minimal opportunity for manual error. Adding more
vSphere hosts to the VM-FEX enabled vSwitch would be simple and require very little
time or effort. By contrast, when we set up our traditional vSwitch, we had to manually
set each individual vSwitch setting on the vCenter GUI or command line. Another
problem with using a traditional vSwitch is that virtual machine networks and VMkernel
names are case sensitive, and require special attention to detail to ensure proper host
and VM communication. In addition, we had to configure several things, such as MTU
speeds at the vSwitch and again at the individual virtual machine networks or VMkernel
interfaces. With the vSwitch solution, you must repeat these processes again each time
you add a host to a cluster, requiring administrative time and creating the potential for
unwanted manual errors.

About the Cisco UCS Manager
The Cisco UCS Manager enables unified, embedded management that
integrates the management of both software and hardware on the Cisco UCS solution.
The UCS Manager centralizes server management, making it easier in several key ways.
First, role-based management makes it easy to assign unique management roles to
different administrators (i.e., server, network, or storage admins) so that each can be
assigned his or her own unique policies and permissions, while still being part of an
integrated management environment. Policy-based provisioning provides managers
with the ability to create service profile templates that they apply to one or 100 servers,
making it easy to apply consistent policies. The Cisco USC Manager makes server
Citrix XenApp hosted shared desktop performance on Cisco UCS:
Cisco VM-FEX vs. traditional vSwitch
A Principled Technologies test report 6
management less about managing isolated, single hardware components and more
about managing many hardware components (up to 20 chassis and 160 blades per
domain) as a single management domain. The use of service profiles allows managers to
allocate and reallocate server resources, which the UCS Manager views as “raw
computing capacity.” This way, server capacity allocation becomes more dynamic and
efficient, with managers able to deploy and reallocate server resources in a matter of
minutes.
To learn more about the Cisco UCS Manager, visit
www.cisco.com/en/US/products/ps10281/index.html.
VM Fabric Extender (VM-FEX) technology
VM-FEX technology allows administrators to manage VM network traffic and
bare metal (i.e., physical) network traffic all from a single unified infrastructure. The
advantages are that UCS Manager bypasses the vSwitch and attaches the VM directly to
the card (or fabric). In addition, VM-FEX offers per-port QoS policies allowing you to
prioritize traffic for each PCI device. Essentially, VM-FEX lets you eliminate the
intermediary and obtain faster performance.

About Login VSI 3.7
Login Virtual Session Indexer (Login VSI) 3.7 is a tool that assesses the virtual
desktop performance, capacity, and scalability of a server. Login VSI incrementally logs
users into virtual desktop sessions and measures the total response times of seven
typical office operations from each session to calculate the VSI Index Average.
As more sessions begin to consume system resources, response times degrade
and the VSI Index Average increases until it is above the Dynamic VSImax. When this
condition is met, the benchmark records a Login VSImax, which is the maximum number
of sessions that the platform can support. The average response time of the first 15
session determines a baseline; the VSImax is baseline x 125% +3000ms. Not reaching
VSImax is an indication of satisfactory end user response time.
For more information about Login VSI 3.7, see www.loginvsi.com/productoverview.

IN CONCLUSION
The switching method you choose for your SBC environment can help
determine performance and the experience that end-users have. We found that
unifying switching with Cisco VM-FEX resulted in up to 29 percent lower latency than a
solution using a traditional vSwitch when running a Citrix XenApp hosted shared
desktop farm. Furthermore, the Cisco VM-FEX solution used up to 53 percent less CPU
than the vSwitch solution did under extreme network conditions. In addition to these
performance advantages, Cisco UCS Manager provides a central point of management
and a simplified method to add vSphere hosts to the VM-FEX-enabled vSwitch, which
can reduce management time and costs.
As our results show, switching to Cisco VM-FEX can provide your users with a
more responsive environment.

APPENDIX B - HOW WE TESTED
INSTALLING AND CONFIGURING INFRASTRUCTURE
Using Cisco UCS manager, we deployed a Cisco UCS B200 M2 (infra), and Cisco UCS B200 M3 (SUT), and installed
vSphere 5.1 on both. We installed Microsoft® Windows Server® 2008 R2 on four virtual machines housed on an ESXi
host (infra). We configured one as an Active Directory® domain controller, DNS server, DHCP server, file server, and NTP
server, one as a vCenter™ server, one as a XenDesktop® licensing server, and one as a XenDesktop Provisioning services
server. We configured AD roaming profiles and folder redirection for all user data and profile management. We then
deployed two more Microsoft Windows Server 2008 R2 virtual machines, one on infra and one on SUT. We configured
these to run Iperf. All storage in testing was generic 10 Gbps NFS. Figure 9 illustrates our setup.

SETTING UP THE XENAPP HOSTED SHARED DESKTOP FARM
To create an 8 node Citrix hosted shared desktop farm on our Cisco UCS B200 M3 server (SUT), we created a
gold image virtual machine, installed Microsoft Windows 2008 R2 and installed Citrix XenApp with all applications
necessary for testing. We created streaming vDisk from the gold image with Citrix Provisioning Services. We then
deployed eight Citrix XenApp Virtual machines using the Provisioning services streamed VM setup Wizard.

Login VSI testing pre-configuration
Before running the tests, we created 140 roaming profiles on the \\dc1\profiles share, and 140 redirected
folders the \\dc1\folders share.
Running the Login VSI benchmark
We used twelve launchers configured in parallel to run a medium workload of up to 140 user sessions on the
Citrix XenApp Farm. Before we tested, we changed the adaptor of all 8 XenApp VMs and Iperf2 to use the vdi-net
portgroup. We started the Iperf job, and then ran the login VSI test. After the test had completed, we rebooted our
launchers and XenApp servers, waited for both to become idle, and then re-ran our tests to confirm our results. We then
set all XenApp VMs and Iperf2 to use the VM-FEX port group and reran our test and confirmation tests.
For more information on how to run a Login VSI test, see: www.loginvsi.com/en/admin-guide/performing-tests.
Running the Iperf tests
We powered off all XenApp VMs and Launchers from previous testing. We changed the adaptor on Iperf2 to use
the vdi-net port group. We ran 3 Iperf tests, changed the Iperf2 adaptor to use the VM-FEX port group and reran our
tests.
