The tests monitored performance statistics during a virtual desktop boot storm and then waited for the systems to 
settle for about 20 minutes. Testing tracked ramp-up, which is the login interval for all 1000 sessions; steady state, 
in which all sessions are logged on and active; and logoff. 
48-Minute Standard Benchmark Mode Test Results 
Login VSI tests were run on 1000 XenDesktop pooled Windows 7 virtual machines hosted on eight Cisco 
HyperFlex HX220c M4S servers with exceptional user performance as represented by the Login VSI Analyzer 
score and latency values (Figures 13 through 19). 
Test result highlights include: 
● 
0.7 second baseline response time 
● 
1 second average response time with 1000 desktops running 
● 
2 seconds maximum response time with 1000 desktops running 
● 
Average CPU utilization of 80 percent 
● 
Average of 300 GB of RAM used (384 GB available) 
● 
Peak network utilization of 408 MBps per host 
● 
Average of 1.9 milliseconds (ms) of I/O latency per cluster 
● 
11,900 peak I/O operations per second (IOPS) per cluster at steady state 
● 
210 Mbps peak throughput per cluster at steady state
