ESX disk

response time

The following graph shows the Average Guest Millisecond/Command counter, which

is shown as GAVG in esxtop. This counter represents the response time for I/O

operations issued to the storage array. The average of both LUNs hosting the replica

storage is shown in the following graph.

The GAVG values for the EFD replica storage and the linked clone storage on the

Pool1_x data stores were below 3.5 ms. This indicates excellent performance under

this load.

View refresh results

Test

methodology

This test was conducted by selecting a refresh operation for all desktops in both

pools from the View Manager administration console. A refresh for all desktops in

one pool was started and was followed immediately by a refresh for all desktops in

the other pool with only a few seconds of delay. No users were logged in during the

test. Overlays are added to the graphs to show when the last power-on task

completed and when the IOPS to the pool LUNs achieved a steady state.

For the refresh test, all vCenter Server tasks completed in approximately 49 minutes.

The first pool completed the refresh tasks after 28 minutes and achieved steady

state after 54 minutes. The second pool completed the tasks after 49 minutes and

achieved steady state after 66 minutes. The start-to-finish time was approximately 66

minutes for all desktops.
