RAID1 Support

Geometrically Increase Your IP-PBX Hard-Drive Reliability

P/N = XR0064
The Xorcom XR2000™ and XR3000™ IP-PBX appliances offer RAID 1 support as an option for increased system reliability. RAID is a technology that employs the simultaneous use of two or more hard disk drives to achieve greater levels of reliability, among other benefits.

The reliability provided by RAID is essential to meet the ‘always-on’ requirements of enterprise-grade telephony installations, and complements the robust feature set and ease of installation and maintenance afforded by the Xorcom IP-PBX solutions.

The diagram above illustrates RAID 1 with the two disks (Disk 0 and Disk 1) over one logical volume, with all blocks replicated/mirrored from Disk 0 to Disk 1. If the active hard disk fails, the second hard-disk automatically takes over and an alarm e-mail is sent to the system administrator. The Xorcom XR2000 IP-PBX or XR3000 IP-PBX unit continues to work seamlessly, and the system administrator can schedule a planned replacement of the faulty disk at a convenient time.

In the Xorcom implementation of RAID 1, two hard disks are supplied.
