RAID Disk Drive Array¶
RAID, an acronym for “Redundant Array of Independent Disks,” is a storage technology that combines multiple hard drives so that data can be stored on them as if they were one logical unit. RAID takes multiple physical disks and makes them appear and function as a single hard disk drive.
Most RAID configurations support write caching. Write caching improves write performance by caching write data in memory and then copying data to the disk array. These systems include battery backup of controller memory to prevent data loss or corruption in the event of a power failure.
Except for the smallest system types (Scout), all MIP servers use some form of RAID to insure data integrity. Depending on configuration three RAID variants: 1, 5, and 6, are used.
