ABOUT RAID AND RAID 5

The Intellex RMS system is configured to support a RAID 5 type of disk array.

While there are several types of RAID (Redundant Array of Independent Disks)

systems, they all allow multiple hard drives to be combined together to form one

large logical drive, called an array. The operating system sees the multiple disk in a

RAID array as a single hard drive; the RAID software or controller handles each drive

on its own.

RAID benefits are substantial: greatly increased overall storage capacity for a single

drive designation, increased server performance due to higher data transfer rates, and

greater fault tolerance that assures the system stays up and running even if a hard

drive fails.

RAID 5 offers high reliability, massive data storage, superior performance, and

exceptional fault tolerance. The RAID 5 type of disk array rotates the parity data

across all physical drives along with the block data. Striping the parity data this way,

across all drives rather than onto a single dedicated parity drive, removes write-

performance bottlenecks and assures a high degree of fault tolerance.
