The Intel HostRAID Confi gurations
The following types of Intel's HostRAID confi gurations are supported:
RAID 0 (Data Striping): this function allows data to be written (copied) into parallel,
interleaved ("striped") sections of two hard drives, achieving double data-transfer
rate than 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) to get the benefi ts of both.
RAID 5: both data and parity information are striped and mirrored across three
or more hard drives.
The Intel Matrix Storage
The Intel Matrix Storage, supported by the ESB2, allows the user to create RAID
0, RAID 1, RAID 10 and RAID 5 sets by using only six identical hard disk drives.
The Intel Matrix Storage Technology creates two partitions on each hard disk drive
to generate virtual RAID 0, RAID 1, RAID 10 and RAID 5 sets. It also allows you
the change the HDD partition size without any data being added or deleted.
