Overview of RAID System
What is RAID (Redundant Array of Inexpensive Disks)?
RAID is an abbreviation for "Redundant Array of Inexpensive Disks". The RAID technology allows
more than one hard disk drive (HDD) to be handled collectively.
In actual, RAID can configure more than one HDDs as a single array (disk group) to operate the
HDDs effectively. This can bring higher performance than a single HDD of a large capacity.
N8403-027 SATA interface card or N8403-026 RAID Controller has a feature to divide a single disk
group into several virtual drives. Operating system recognizes these virtual disks as if it were a
single hard disk drive. Operating system accesses to more than one hard disk drive configuring a
disk group in parallel.
Some RAID levels can recover data from remaining data and parity by using rebuild feature if an
error occurs in a single HDD. This can provide high reliability for the system.
