Tests utilizing four combinations of workload and resolution were run to determine the impact on
end-user experience. They were medium workload with low resolution, heavy workload with low
resolution, medium workload with high resolution, and heavy workload with high resolution.
Two tools were used to ascertain a complete picture of end-user QoE. The Stratusphere UX
virtual appliance, a software-based desktop monitoring tool housed on the Infrastructure Host,
made a visual recording of desktop activity that allowed subjective evaluation.
Installed on a golden image of a virtual desktop, the Stratusphere agent pushed all data related
to end-user experience to the Stratusphere UX for rating QoE. The overall quality was rated in
the upper right (best) quadrant, indicating both best interactive experience and best quality of
display rendering.
In addition, an objective evaluation of end-user experience was made using the OmniPeek
network analyzer from WildPackets, Inc., which monitored network utilization during the test of
the S6000 switches and the ESXi hypervisor resource. OmniPeek was placed on the link
between a S6000 switch and the 6248 switch. It monitored traffic passing through the S6000
switches from the vSphere servers via the S5000 switches.
Tests Combining Medium and Heavy Work Load with XGA Desktop
In a test that combined
multiple Horizon View clients, which logged into the virtual desktop at 60-second intervals. CPU
capacity was verified to be near maximum.
The end-user experience of all 203 virtual users was rated as fully satisfactory by Stratusphere
UX. A S6000 switch was the backbone of a subnet on which all 203 users ran concurrently.
