Each PowerStore X model node has VMware ESXi installed on it. Each node requires a VMware vSphere Enterprise Plus license, which can be applied after the appliance is installed. You can provide your own license or purchase one along with the PowerStore X model appliance.
Starting with PowerStoreOS 1.0.3, vSphere Remote Office Branch Office (ROBO) licenses can be installed on PowerStore X model nodes. PowerStore X models support both the vSphere ROBO Advanced and ROBO Enterprise licenses. ROBO edition licenses are limited to 25 virtual machines, including the PowerStore X controller VMs. During initial configuration of the PowerStore X model appliance, the appliance automatically enables Distributed Resource Scheduler (DRS) in partially automated mode. vSphere ROBO Advanced licenses do not support DRS, and vSphere ROBO Enterprise licenses only support DRS for entering maintenance mode. Before installing a ROBO license on a PowerStore X model node, you must disable DRS on the ESXi cluster. When using a vSphere ROBO license, the user must manually initiate VM load balancing.
For more information about the ROBO license support, see the VMware document VMware vSphere Compute Virtualization: Licensing, pricing and packaging.
Starting with PowerStoreOS 3.2.0, PowerStore X systems issue alerts about expiring internal ESXi licensing. The system provides a warning-level alert that the underlying internal ESXi host’s license will expire in x number of days. Once a permanent license is applied to the internal ESXi host, the warning alert is cleared automatically, and the system issues an informational alert of ESXi internal host is permanently licensed. The alerts are shown in PowerStore Manager under Monitoring > Alerts, as shown in Figure 27.
