Dell PowerStore Virtualization Infrastructure Guide

Virtualization architecture and configuration

In PowerStore T and PowerStore Q model clusters, a connection to a vCenter Server is optional and can be set up either during initial system configuration, or later in PowerStore Manager. Using vVol-based VMs on a PowerStore cluster requires registering the PowerStore VASA provider in vCenter.

If the VASA provider is not registered during initial system configuration, it can be registered in one of the following ways:

• The VASA provider can be registered when a connection to vCenter Server is configured in PowerStore Manager.
• The VASA provider can also be registered directly from vCenter, but additional steps are required.
  NOTE:If a VASA provider is registered directly from vCenter, but a vCenter Server connection is not configured, PowerStore Manager cannot manage vVol-based VMs. Therefore, registering the VASA provider during the configuration of a vCenter Server connection in PowerStore Manager is recommended.

The PowerStore Resource Balancer manages the placement of vVols and keeps vVols for the same VM on the same appliance in a cluster. You can also migrate a vVol-based VM from one appliance to another from the Virtual Machines page of PowerStore Manager.
