## integrated RAID controller

An integrated SCSI controller with RAID capabilities, such as the LSI 1020 and LSI 1030. Integrated RAID controllers are standard features on some IBM xSeries servers. They can be used to create a RAID level-1 logical drive from two physical drives or a RAID level-1E drive from up to six physical drives. You can configure one additional physical drive as a hot spare drive for both RAID levels.
