Basic storage partitioning
The following illustration shows the functionality of partitioning. Partitioning the
storage provides flexible management of available storage by subdividing the
storage into separate independent sections or partitions. It also enables you to
consolidate the storage from multiple host systems into one or more FAStT500
RAID Controller Enclosure Units and amortize the cost of the storage across the
connected hosts rather than having one host incur the total cost of the storage.
Note: Four partitions are shown. Eight are available in the base configuration.
