Maintaining the JATP700 RAID Array

Redundant array of inexpensive disk (RAID) is a method of storing large amounts of application data used for data redundancy, performance improvement, or both. There are different RAID levels designed to increase data reliability and I/O performance.

The key concepts in RAID are:

  • Mirroring—Copy data to more than one disk

  • Striping—Split data across more than one disk

  • Error correction—Redundant data storage to detect and resolve problems

The JATP700 appliance uses the RAID6 configuration. In RAID6, drives are duplicated for fault tolerance.
