RAID
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.
The Onboard RAID Controller (LSI Embedded MegaRAID) or 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.
