Disk storage

Storage capacity can be expanded by adding external hard disk towers to your microCT system. Particularly attractive is the addition of disk towers configured with RAID 5 disk arrays, which store your data on multiple disks automatically, helping to protect you from data loss. Hot spare disks can be included for extra peace of mind.

SAS disks are recommended for highest performance. SATA disks offer a cost-effective upgrade path when capacity and cost take priority over absolute performance.

A maximum of 5 D2600 and D2700 arrays can be connected in cascade per RAID controller.

HP disk towers carry a one (SATA, midline SAS) or three-year guarantee (SAS enterprise) with next working day exchange in the event of disk failure.

RAID

Redundant Array of Inexpensive Disks

RAID 1

Mirroring
Data are stored automatically onto two hard disks. Data are preserved even if one disk fails.

RAID 5

Distributed storage
Disks are grouped so that data and recovery information are stored on separate disks. In the event of failure of a single disk, no data are lost.

Hot spare

Spare disk within RAID array that stands-in automatically when a disk fails. Redundant storage of data is maintained.
