The Virtual Volume architecture not only gives VMware insight into the FlashArray, but it also gives the FlashArray insight into VMware. The granularity provided by Virtual Volumes gives the FlashArray the ability to understand the virtual machine object (volume group) and its various virtual disks (volumes).
Data Reduction Reporting
- As noted in previous sections, a VM is represented on the FlashArray as a volume group. By clicking on the Storage pane and then the Volumes tab, you can see the volume groups. Click on the one that represents your virtual machine.
- The top panel of the volume group shows averaged or aggregate information for your virtual machine. If you click on the Space button in the Volumes box, the space stats will be displayed for the individual vVols as well.
- To see historical information, click on the Analysis pane and choose Capacity and then the Volumes tab.
- To look at VMs (volume groups) or vVols (volumes) click on the drop down and choose the appropriate object type.
- Once selected, look through the objects and select it to see the VM or vVol of your choosing. Alternatively, type in the name of the VM into the search box and the listing will be filtered automatically. Up to 5 volumes or 5 volume groups can be selected in the GUI.
Performance Reporting
- VM and vVol performance can also be reported on. By click on the Analysis section and the Performance sub-section, details like IOPS, latency, and throughput can be viewed. Click on the Volumes tab to find the various VMs (volume groups) or vVols (volumes).
- To see report on a VM, choose volume groups in the drop down. To see specific vVols, choose volumes.
The analysis tab will breakout the performance stats (IOPS, throughput, and latency) in different charts, which can be split further into Reads or Writes. For VM latency, it is averaged for all volumes in that VM. For throughput and IOPS, it is accumulative across the volumes. If a specific volume is selected, they are the stats for just that volume.
