VMAX 20K TDEV performance monitoring?

Hi,

Assuming you have the performance analyzer software in Unipshere you can utilize the Analyze > Diagnostic view. If you double-click on the array serial number and then the storage group tab it will give you a list of the SG's to chose from. Once you chose the one you want to monitor you can double click it and it will dive into the volumes that make up that storage group - TDEVs, Meta's, thick, etc.

Once you have drilled down to that level, you can see all of the LUNs and what their individual metrics are. If you have a LUN in the storage group that is a Meta TDEV, then you can double-click on it again and it will go even further to show you the metrics on the individual members that comprise that Meta TDEV. This will give you an idea of is the metavolume is balanced across all members, and what the individual workload is on the individual LUNs of a storage group.

If you want to go even further to the disk level, you can keep double-clicking on the entity to drill down to that level (for example, you can double-click on a meta member that makes up a metavolume and it will show you the physical disks that the volume resides on and the metrics associated with that disk).

Also in the Analyze portion of the GUI (where you would do all of this) you can use Unisphere to build charts from the various KPI's and then add them to your main dashboard....this way you can have a quick glance at any time of the desired performance metric and a timeline to quickly view any erratic performance versus having to drill all the way down again.

HTH,
