The steady state workload phase follows the login phase. Steady state starts once all the users are logged in and are performing their daily tasks. Login VSI is configured to run at steady state for 30 minutes for this test. The figures below show the key PowerEdge and PowerStore performance metrics during steady state.
During steady state, IOPS and bandwidth decrease and level off, with an average latency of less than 0.29 milliseconds.
The read/write ratio shows a higher percentage of writes during steady state. In this test, the data points in the call-out in Figure 25 show a sustained bandwidth of 207 MB/s reads and 896 MB/s writes. During steady state in this test, 19% of the bandwidth consists of reads, and 81% consists of writes.
Steady state shows a considerable drop in IOPS.
Write latency is slightly higher than read latency due to the 19% to 81% read/write ratio. Overall latency is consistently between 0.3 to 0.4 milliseconds.
Storage CPU demand is also less during steady state, averaging about 20%, with latency performance averaging less than 0.4 milliseconds.
The PowerEdge R6525 hosts also show a decrease in CPU utilization during steady state, averaging around 65%, with memory utilization around 90%.
The CPU usage that is shown in iDRAC9 shows a similar pattern as the storage array. During steady state, PowerEdge R6525 CPU usage is about 50%.
