This white paper describes the fully redundant hardware and high-availability features that are available on Dell PowerStore. These features are designated to withstand component failures in the system and in the environment, such as network or power failures. If an individual component fails, the storage system can remain online and continue to serve data. The system can also withstand multiple failures if they occur in separate component sets. After the administrator is alerted about the failure, they can order and replace the failed component without any impact.
