Glossary

Array

Also known as Disk Array, two or more hard disks combined together to appear as a

single device to the host computer.

RAID

Redundant Array of Independent Disks, it is a method of combining several hard

disks (physical disks) into one logical unit (logical disk), thus providing higher

performance and data redundancy.

RAID Levels

RAID levels refer to different array architectures (or methods of organizing a disk

array). Different RAID levels represent different performance level, security level and

cost.

Striping

Known as RAID 0, spread data over multiple disks to improve performance. It does

not provide data protection.

Mirroring

Known as RAID 1, which provides data protection by real-time and automatic

duplicating all data from a source disk to a mirror disk.

RAID 1/0

It is the combination of RAID 1 and RAID 0.
