E.1 Introduction
The Intel
®
ICH7R chipset can provide data protection for serial ATA (SATA) disks via the
Intel
®
Matrix Storage Manager using one of three fault-tolerant RAID levels: RAID 1, 5 or
10. When using two hard drives, matrix RAID allows RAID 0 and RAID 1 functions to be
combined, where critical files can be stored on RAID 1, and RAID 0 can be used for
non-critical items such as software. RAID 5 and RAID 0 can be combined to provide
higher performance, capacity, and fault tolerance.
CAUTION!
A configured RAID volume (which may consist of multiple hard drives) appears
to an operating system as a contingent storage space. The operating system
will not be able to distinguish the physical disk drives contained in a RAID
configuration.
E.1.1 Precautions
One key benefit a RAID configuration brings is that a single hard drive can fail within a
RAID array without damaging data. With RAID1 array, a failed drive can be replaced and
the RAID configuration restored.
WARNING!
Irrecoverable data loss occurs if a working drive is removed when trying to
remove a failed drive. It is strongly recommended to mark the physical
connections of all SATA disk drives. Drive locations can be identified by
attaching stickers to the drive bays. If a drive member of a RAID array should
fail, the failed drive can then be correctly identified.
