1 Overview
The disk array system uses groups of inex-
pensive disks to provide flexibility when
balancing data availability, access rate, and
capacity management needs.
High data availability is achieved by using
the fault tolerance features of RAID
(Redundant Array of Inexpensive Disks);
hot spare disks with automatic on-line
rebuild; hot swap disks, power supplies, and
fans; independent serial ATA (SATA) disk
controllers; and dual host controllers. Our
confidence in the disk array system is
backed by a three year warranty.
A high data access rate is achieved by combining the individual data rates of serial ATA disks in
a RAID configuration. Serial ATA disks lack some of the features of SCSI disks but are just as
fast when used with a high performance RAID controller. In the disk array system, RAID is con-
trolled by a high performance CPU, which transfers data through dual host interfaces at the max-
imum possible rate.
Flexible data capacity management is achieved with on-line RAID expansion, RAID capacity
division into slices, and multiple logical RAIDs. Management is performed through front panel,
or RS-232 interfaces.
