Redundancy
Overview
This guide will cover the installation procedures required to install a
Redundancy kit and secondary Hard Disk Drive (for RAID purposes) into the
BCM 450 chassis.
By combining a RAID solution, redundant power supply and secondary fan - a
BCM 450 can be safeguarded against any significant down time or data loss
in all but the most severe scenarios.
Note: BCM450 systems can also be ordered pre-installed with the
redundancy options. This guide can be used as referential material to help
identify the redundant components. However, redundant component
replacement procedures can be found in the BCM450 Hardware and
Installation Guide. Refer to the Replacing Internal Components section for
information on replacing the redundant hard drives, cooling fan, power supply,
and redundant power supply modules.
Requirements (Redundancy):
The BCM must be placed on a suitable flat surface.
There must be ample room to remove the access cover and work
unhindered.
The BCM should not be near the exhaust of any other operating
equipment.
If required, a suitable earthing strap must be worn when working
directly on any internal circuitry.
Requirements (RAID):
RAID functionality on BCM 6.0 is enabled through a keycode that
comes with the RAID Hard Disk Drive.
Ensure you have the Keycode file with RAID entitlement.
Any new Hard Disk Drive must be equal to or greater in size than the
drive to be mirrored.
Once installed the BCM will take slightly longer to reboot due to new
disk synchronisation.
Disk mirroring does not effect any services running, but will reduce the
performance of the BCM until the mirror is completed (usually no more
than 1 hour) therefore it is advisable to schedule this work during a
quiet period.
Access to Element Manager (to enable the RAID service).
