Fault Handling and Recovery

An array that has the DE feature enabled can handle array component
failures without experiencing any additional degradation in data
availability or data recoverability, compared to an array that does not
used the DE feature. This includes but is not limited to failed and offline
controllers, failed drives, failed drive trays, pulled cables, and failed
firmware downloads.
