The hard disks are one of the hardware components most likely to fail in a system; therefore, it is important for a high-availability system to implement a hard-drive redundancy feature.

RAID
Although many solutions are available to achieve this goal, the page will talk more specifically about RAID, which is included in some of TelcoBridges' products.
RAID level
TelcoBridges has RAID level 1 included in the following products:
It is recommended to use at least RAID level 1 to have a fault tolerant system.
RAID implementation
There are mainly 3 types of implementation of RAID:
- Hardware RAID
- BIOS RAID (not recommended)
- Software RAID
Latest TelcoBridges products containing RAID uses the hardware implementation.
Recommended Setup
TelcoBridges highly recommend either storage area network (SAN) and/or RAID 1 and up. The TSBC-HW-SRV and TMG7800-CTRL include RAID 1 hard disk redundancy.
