PFR 600/E circuit board modules
There are two circuit board modules used: the Loop Bypass Board module (LBB) and
the RAID Controller module. The LBB module contains one Loop Bypass Board
which provides an internal Fibre Channel loop for the disk modules installed in the
chassis. The RAID Controller module also contains a Loop Bypass Board plus a
RAID Controller board used to manage the disk drives and provide a Fibre Channel
interface to the Profile system.
PFR600 RAID Storage Chassis circuit board modules
The PFR600 includes one or two RAID Controller modules. Two RAID Controller
modules are installed when the redundant Fibre Channel option is installed. This
provides redundant Fiber Channel interface ports to the Profile system or Fibre
Channel switch fabric.
The following figure shows a PFR600 RAID Storage Chassis with the two RAID
Controller Modules installed. RAID controllers can be installed in either position, top
or bottom. The one in the bottom position is identified as Controller A, the one in the
top position is identified as Controller B.
