PowerStore T models support a unified configuration (file storage and block storage). If file services are not needed, choose block-optimized during the initial configuration of the hardware. When a PowerStore T model appliance is configured as unified, some compute and storage resources are reserved for NAS services, even if NAS is not used.
Note: If file services (NAS) might be needed later, select Unified during initial configuration. After an appliance is configured to support unified, the appliance must be reinitialized to change the configuration.
All PowerStore models support multipath I/O (MPIO) front-end connectivity to hosts. More information about MPIO is covered later in this document.
