PowerStore T models and PowerStore X models offer deep integration with VMware vSphere. These integrations include VAAI and VASA support, event notifications, snapshot management, storage containers for virtual volumes (vVols), and virtual machine discovery and monitoring in PowerStore Manager. By default, when a PowerStore T model or PowerStore X model is initialized, a storage container is automatically created on the appliance. Storage containers are used to present vVol storage from PowerStore to vSphere. vSphere mounts the storage container as a vVol datastore and makes it available for VM storage. This vVol datastore is then accessible by internal ESXi nodes or external ESXi hosts. If an administrator has a multi-appliance cluster, the total capacity of a storage container spans the aggregation of all appliances in the cluster. For PowerStore X model appliances, the cluster Distributed Resource Scheduler (DRS) is set to partially automated mode. Because the appliance is optimized for and expects this configuration, changing these settings is not supported.
