The FlashArray GUI can also report VM and vVol performance hostory. In the Analysis pane Performance view, the history of a VM or vVol’s IOPS, latency, and data throughput (Bandwidth) can be viewed.
Click the Volumes tab to display a list of the array’s VMs (volume groups) and/or vVols (volumes).

GUI Analysis Pane
|
To view an object’s performance history, select Volume Groups, Volumes, or All in the dropdown, and select a VM or vVol from the resulting list.
|
Selecting Volume Display
|
A VM’s or vVol’s performance history graph shows its IOPS, throughput (Bandwidth), and latency history in separate stacked charts.
The graphs show the selected object’s performance history over time intervals from 24 hours to 1 year. Read and write performance can be shown in separate curves. For VMs, latency is the average for all volumes; throughput and IOPS are an accumulation across volumes.

The vVols architecture that gives VMware insight into FlashArrays also gives FlashArrays insight into VMware. With vVol granularity, array can recognize and report on both entire vVol-based VMs (implemented as volume groups) and individual virtual disks (implemented as volumes).
