PowerStore features fully redundant hardware and includes several high availability features. These features are designed to withstand component failures within the system itself and environmental failures such as network or power outages. If an individual component fails, the storage system remains online and continues to serve data. The system can also withstand multiple failures if they occur in separate component sets. After the administrator is notified about the failure by call-home or onboard system alerts, they can order and replace the failed component without impact.
PowerStore is a dual-node architecture that includes two identical nodes for redundancy. It features an active/active controller configuration where both nodes are servicing I/O simultaneously. This increases hardware efficiency since there are no requirements for idle standby hardware. These nodes, along with up to twenty-five 2.5-inch drives, are enclosed within the base enclosure, all in a 2U form factor.
The following sections cover the different hardware components of the PowerStore platform. Specific sections detail the redundancy and high availability features of that component and how it pertains to PowerStore. For more information about high availability at the software and cluster level, see the document PowerStore: Clustering and High Availability on the Dell Technologies PowerStore Info Hub.
