Each RAID Controller module includes a Loop Bypass Board (LBB). These boards
provides internal Fibre Channel loops for the disk modules. In the event of an LBB
module failure, the faulty loop is bypassed and all disk drives failover to the
remaining LBB module.
The LBB in the PFR600 RAID Controller module has two Fibre Channel ports: the
Fibre Channel Host Port and the Fibre Channel Loop Port. Copper or optical SFP
(Small Form-factor Pluggable) modules are used in the Host Fibre Channel ports to
connect Fibre Channel cabling to a Profile XP Media Platform or to a Fibre Channel
switch in an Open SAN fabric, respectively. Optical SFP modules are used in the
Fibre Channel Loop ports to connect to a PFR600E. This extends the Fibre Channel
loop of the corresponding PFR600 chassis. There is a port status LED for each Fibre
Channel port. Refer to
“Interpreting rear panel status LEDs” on page 42 .
