Voice Storage System

RAID Hard Drive

The RAID hard drive option was introduced in 2004 and replaces the Mirrored Drive

option. The RAID hard drive consists of two high performance IDE drives housed in a

special chassis that controls the drives and automatically keeps them synchronized. Both

drives contain identical data and either one may serve as backup to the other. The RAID

chassis presents a standard SCSI interface to the CPU and thus requires no operating

system or paging software changes. All intelligence required to manage the process is

contained in the RAID chassis. The RAID drive solution is superior to the old Mirrored

Drive option because all system files are backed up, not just the voice files, plus a backup

drive can be removed and replaced with power on. This allows the system operator to take

a system snapshot at any time and remove the drive for off-site storage. The RAID

controller firmware continually monitors each drive's operation and if it senses that a drive

has failed or is failing, all accesses are directed to the working drive and the unit will

sound an audible alarm. Note that the RAID hard drive option is for the M2200 only and is

not offered for M2100 terminals because of limited space to mount the drive.

If you purchased your system with the RAID option installed, the drives are installed, the

software is loaded and all files are synchronized. If you have purchased the RAID drive

option as an upgrade and are installing it yourself, the following documents should have

come with the hardware components. Follow the instructions in the documentation

carefully.

011-0664 Transferring Files From Old SCSI to RAID Drive

011-0665 M2200 RAID Drive Duplication Procedure

The following sections contain instructions for installing and working with the RAID

drive components and for transferring data from the old SCSI drive to the RAID drive.

Please read them for an understanding of how the RAID system operates and how to

duplicate drives and work with the files.

RAID Drive Option Installation (011-0662)

TOOLS: #1 Phillips screwdriver, Office PC with ZbaseW.

♦ Installing the RAID drive

1. The RAID hard drive hardware consists of two removable 2.5 inch IDE hard

drives, a RAID controller chassis that fits into a 3.5 inch hard drive bay and a cable

adapter.

2. If you have a Pentium CPU and your disk drive is mounted in the drive bay below

the backplane, remove the SCSI drive and mounts by removing the two front

screws and loosening the two rear screws. If you are upgrading from a Zetron Hard

Card perform steps 3 - 4 to install the disk mounts and cabling otherwise skip to

step 5.
