Logical Drive Info: This displays information how the logical drive will appear to the
computer and the operating system. In all RAID configurations, the drives in your array
will appear to be a single physical drive. If you wish, you can partition the logical drive
space into multiple partitions using your operating system.
IMPORTANT: If you want your computer to boot from your RAID, you must configure
your computer’s BIOS to use the drives connected to the PCISATA2P4 in your boot
sequence. Depending on the options available, you must set your boot sequence to
include RAID or SCSI to use the RAID as the boot drive, particularly if you have ATA
hard drives connected to the motherboard’s IDE controller. Depending on the
configuration of the computer, you may not need to make any changes to the BIOS if you
do not have any ATA hard drives installed on the onboard IDE controller. Consult your
computer or motherboard documentation for more details on including the RAID card in
your boot sequence.
Configuring an Array
When you choose Create a RAID set from the Main Menu of the RAID utility, you will be
presented with the following menu:
The requirements for each option/RAID level are described here:
RAID0: Also called “disk striping,” where multiple physical drives are merged to create a
single logical volume.
Minimum number of drives: 2
Maximum number of drives: 4
Fault tolerance: None
Performance: Excellent; improves both read and write performance
Other considerations: None
RAID1: Also called “drive mirroring,” where a drive has an exact duplicate copy of data
maintained on another disk.
Minimum number of drives: 2 (per array)
Maximum number of drives: 2 (per array)
Fault tolerance: Excellent; complete redundancy
Performance: Good; some reduction in write performance
Other considerations: 50% reduction in useable space as the drive containing
the mirror is not available to the user; drives must be identical
RAID10: Also called RAID 0+1, this is a combination of disk striping (RAID 0) and
mirroring (RAID 1). Two disks are striped together in a single volume, with a mirrored
striped set for redundancy.
Minimum number of drives: 4
