<p>create hard disk page</p> <p><b>New page</b></p><div>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.<br /> <br /> === [http://en.wikipedia.org/wiki/RAID| RAID] ===<br /> Although many solutions are available to achieve this goal, the page will talk more specifically of RAID which is included in some of TelcoBridges' products.<br /> <br /> ==== [http://en.wikipedia.org/wiki/Standard_RAID_levels| RAID level] ====<br /> TelcoBridges has RAID level 1 included in the following list of products:<br /> [[TMG5800]], [[TMG7800]], [[TMP5900]], [[TMP7900]], [[TMP7950]] and [[TMG8300]]<br /> <br /> It is recommended to use at least RAID level 1 to have a fault tolerant system.<br /> <br /> ==== RAID implementation ====<br /> There are mainly 3 types of implementation of RAID:<br /> *Hardware RAID<br /> *BIOS RAID (not recommended)<br /> *Software RAID<br /> <br /> TelcoBridges products containing RAID uses the software implementation.<br /> As the name state, the hard disk redundancy is handled by the OS. Of course, it requires an OS that is supported like CentOS.<br /> <br /> == Recommended Setup ==<br /> <br /> TelcoBridges highly recommend either storage area network (SAN) and/or RAID 1 and up.<br /> The [[TMG5800]], [[TMG7800]], [[TMP5900]], [[TMP7900]], [[TMP7950]] and [[TMG8300]] comes with RAID 1 hard disk redundancy.</div>
