RAID Confi gurations
The following types of RAID confi gurations are supported:
RAID 0 (Data Striping): this writes data in parallel, interleaved ("striped") sections
of two hard drives. Data transfer rate is doubled over using a single disk.
RAID1 (Data Mirroring): an identical data image from one drive is copied to another
drive. The second drive must be the same size or larger than the fi rst drive.
RAID 10 (Striping & Mirroring): RAID 0 and 1 schemes are combined (without parity
information) to get the benefi ts of both.
RAID 5: both data and parity information are striped and mirrored across three or
more hard drives.
Intel Matrix Storage
The Intel Matrix Storage, supported by the ICH7R, allows the user to create
RAID 0 and RAID1 set by using only two identical hard disk drives. The Intel
Matrix Storage Technology creates two partitions on each hard disk drive and
generate a virtual RAID0 and RAID1sets. It also allows you the change the HDD
partition size without any data.
