RAID disk drive array

RAID, an acronym for “Redundant Array of Independent Disks”, is a storage technology that combines multiple hard drives to store data as if they were one logical drive.

Except in the case of the smallest systems (Scout) O/S software and data are stored separately. O/S software is stored on a two disk mirrored array using solid state drives for improved performance. Large servers use some form of RAID to insure data integrity, Volicon uses three RAID variants: 1, 5 and 6.

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 RAID controller memory to prevent data loss or corruption in the event of a power failure.

Volicon MIS uses enterprise-class SATA drives for maximum performance and reliability.
