The above table lists the RAID 5 configurations having redundancy for security. The
RAID 5 configuration includes hot spare disks used if a hard disk failure occurs. It
permits creation of two logical volumes in an additional disk cabinet, which pr events
all the disks in the cabinet from being disabled if a failure occurs. Other RAID
configurations are available. It is important to take system availability into
consideration in designing a configuration.
Refer to the NAS User's Guide in order to re-configure your disks.
