RAID
Overview of the RAID System
What is RAID?
RAID is an abbreviation for "Redundant Array of Inexpensive Disks". The RAID technology
allows several hard disk drives (HDD) to be handled collectively.
RAID can configure several 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.
Internal RAID Controller has a feature to divide a single disk group into several logical drives
(virtual disks). 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.
NOTE:
When A1080a-E model, two RAID Controllers are configurable.
The RAID Controller connected to the lower(younger) number of
the PCI slot is called as RAID Controller 1.
IMPORTANT:
This is the guide to use of the NE3104-001/003 RAID controller.
For an explanation about NE3104-004 RAID controller, refer to the
User’s Guide provided with NE3104-004 RAID controller.
