RAID1 Support for IP-PBX

Geometrically Increase Your IP-PBX Hard-Drive Reliability with RAID1 Support

P/N = XR0064

The Xorcom CXE2000, CXE3000, XE2000 and XE3000 IP-PBX appliances offer built-in RAID1 support 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.

RAID1 Support in Xorcom IP-PBX

In the Xorcom implementation of RAID1, two hard disks are supplied.

The diagram at right illustrates RAID1 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 XE2000 IP-PBX or XE3000 IP-PBX unit continues to work seamlessly, and the system administrator can schedule a planned replacement of the faulty disk at a convenient time.
