swappable modules. This improves serviceability and increases fault tolerance by
eliminating any single point of failure. With two RAID Controllers, the two loops
within a single standard chassis are configured as a single loop with a backup loop in
standby mode.
Capacity and redundancy
The PFR 500 contains five or ten half-height 3.5" Fibre Channel Arbitrated Loop
(FC-AL) disk drives. The chassis also supports one or two hardware RAID
Controllers in one 3U high rack-mountable chassis. The PFR500 currently uses 73GB
or 180GB drive capacities. With ten drives, one chassis holds up to 730GB or 1.8TB
depending on the disk drive option.
The PFR 500E RAID Expansion Chassis provides additional storage capacity. It is an
identical chassis with two Loop Bypass Board installed. Up to nine PFR 500E RAID
Expansion Chassis can be connected to a single PFR500 comprising a single
disk-array storage system with a total of 100 drives and 7.3TB or 18TB of storage
depending on the disk drive option. The built-in chassis daisy-chaining capabilities
provide for cost effective storage expansion as requirements grow.
Throughout this manual, the term PFR 500/E is used to refer to either the PFR500 or
the PFR500E interchangeably.
PFR500/E components
The PFR 500/E components are:
• The chassis with passive midplane board
• One or two RAID controllers (PFR500 only)
• One or two Loop Bypass Boards
• As many as ten Fibre Channel disk drives per chassis
• Two power supplies
• Two fan modules
The RAID Controllers, Loop Bypass Boards, disk drives, power supplies, and fan
modules are hot-swappable field replaceable units (FRUs), which means you can add
or replace them while the PFR 500/E is powered up.
An optional second RAID Controller Module in the PFR 500, allows for continued
access to the PFR 500 if the primary RAID Controller fails. Adding a second RAID
Controller to the same chassis is not intended to increase performance, but rather to
add redundancy
.
Refer to your Profile XP PVS Series Installation Guide for detailed
connection and configuration instructions.
NOTE: Hotswapping the RAID Controller or LBB modules (removing or inserting)
causes approximately a 10 second loss of video (record/play). This happens
regardless of whether you exchange the primary controller or the secondary
controller.
The following figure shows the PFR500/E components. Details on each component
follow the figure.
