Uncompromised virtual desktop performance
and applies the formula Baseline x 125% +3000, when the VSI index is higher than the dynamic
baseline then dynamic VSI Max is achieved. In our testing, Dynamic VSI Max was calculated to be
182 sessions.
It is important to note that variations in hypervisor, application, guest OS, and VDI
settings can have a significant impact on expected user density in these tests. Tuning frames per
second, image compression, screen resolution, and other user-experience-specific settings can
increase or decrease the number of desktops a system can support. Generally, improving user
experience will decrease the number of supported desktops. It is therefore important to
understand and quantify the specific needs of VDI users and create baseline settings to ensure
the results are representative of your environment. For more details on the settings used in our
testing, see Appendix B.

SUMMARY
A server that supports a greater density of hosted virtual desktops without sacrificing
performance will minimize the cost of your infrastructure and improve ROI. In our tests, the
Cisco UCS B200 M3 Blade Server running Citrix XenDesktop 5.5 provided impressive virtual
desktop hosting density. The Cisco UCS solution delivered 182 concurrent Citrix XenDesktop
virtual desktop sessions with acceptable user response times and minimal bandwidth usage.
