disk mirroring

(hardware, storage)
Use of one or more mirrors of a hard disk.

disk mirroring

The recording of redundant data for fault tolerant operation. Data are written on two partitions of the same disk or on two separate disks within the same system. Disk mirroring uses the same controller. RAID 1 provides mirroring, which was first accomplished only with SCSI drives, but later with ATA (IDE) drives. See disk duplexing and RAID.


Mirroring on a Budget
Arco was one of the first companies to offer RAID 1 mirroring using two inexpensive ATA (IDE) drives. The motherboard cable plugs into a PCI card or the drive bay version (above), and two cables go out to primary and secondary drives. If one fails, the other takes over.
