The HP FastRAID Option
The HP FastRAID Option
HP FastRAID uses RAID technology to accelerate the performance of
your PC’s hard drives. Rather than focussing on data protection, as
with server-based RAID technologies, HP FastRAID brings top
performance to your computer.
If you purchased your computer with the HP FastRAID option, an
Adaptec ARO-1130 PCI RAID
port
™
adapter will have been pre-
installed in the RAID port connector slot of your PC’s system board, and
configured to provide maximum I/O throughput for your PC’s two hard
drives.
Although your ARO-1130 adapter and hard drives come preconfigured
for maximum performance (RAID 0), you can also configure the
RAID
port adapter and drives to provide protection against data loss
(RAID 1).
The RAID 1 configuration provides software mirroring and caching.
Data is mirrored (duplicated) using a disk pair. If one disk fails, the
data is still available on the mirrored drive. The RAID 1 configuration
also provides an improvement in performance using the cache on the
ARO-1130 adapter. It does not, however, provide the same level of
throughput as the RAID 0 configuration. Also, because data is
mirrored, the storage capacity of your drives is only half of the physical
capacity of the drives.
Note that configurations RAID5 and RAID10 are not supported.
CAUTION Before you reconfigure your drives, back up any existing data that you
wish to keep. Re-configuring an array using the Array
Config utility
erases all data and partitions from the drives. Once you have re-
configured the drives and have reinstalled the operating system you can
restore the backed up data.
