When administrators are using virtual machines on the PowerStore T/Q model appliances, we recommend enabling vSphere HA on the cluster. If a node or host in the cluster loses power, virtual machines restart on a surviving host or node in the cluster.
PowerStore T/Q model appliances enable integration with VMware environments by being managed and monitored from a vCenter. For PowerStore T/Q model appliances, a vCenter connection is optional after the cluster has been set up. After a cluster has been deployed, there could be certain situations where a vCenter connection is lost to the PowerStore appliance. In this scenario, management tasks through vCenter might be temporarily unavailable. Note that I/O continues to be processed for all storage objects in the PowerStore appliance.
