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.
