Conguring 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:
For each option/RAID level are as follows:
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 usable 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
• Maximum number of drives: 4
• Fault tolerance: Excellent; complete redundancy
• Performance: Good; some reduction in write performance
• Other considerations: 50% reduction in usable space as the drives containing the mirror is
not available to the user; drives must be identical
SPARE DRIVE: This is used in conjunction with RAID 1 (mirroring) and allows the computer to keep
running in the event of a drive failure without user intervention, even if it is the boot drive that has
failed. Also referred to as RAID 1+S.
• Minimum number of drives: 1 (requires an associated RAID 1 array)
• Maximum number of drives: 1 (requires an associated RAID 1 array)
• Fault tolerance: Adds seamless disaster recovery to a RAID 1 conguration
• Performance: Not applicable
• Other considerations: Drive is not available to the user; drive must be identical to the models
used in the associated RAID 1 array
