Description:
Our storage is split up in to different performance tiers. These are presented as datastore clusters in vCenter with names which denote the various IOPS limits & technology in use. Each cluster is formed of numerous vmfs datastores, which just increment numerically as they are added to provide more storage capacity. These can be moved between clusters depending on demand, so there is no naming convention for them specific to a cluster.
When a VM is deployed, a cluster is selected for it based on the desired storage tier. Once provisioned that cluster selection is no longer shown and instead only the datastore each disk resides on is displayed.
This gives no meaningful information to the user about the performance tier that an instances was deployed to or resides on.
Adding additional confusion, the storage “type” of Standard is always shown which can be misleading since our “S” tiers refer to Standard, and our “U” tiers refer to Ultra.
Example/Use case(s):
It would be really beneficial to display the cluster alongside the datastore that an instance resides on, so that a user knows what performance tier their server is running on. This may help them to troubleshoot performance issues, or decide to migrate to a faster tier if required.
