20 September 2002 PFR500/E Instruction Manual 15
Chapter 1
About the PFR500/E
This chapter introduces the PFR500 Fibre Channel RAID Storage Chassis. Topics
include:
•PFR500/E features
•PFR500/E components
•Configurations
PFR500/E features
The PFR500 Fibre Channel RAID Storage Chassis is a high performance, high
availability mass storage system. High-bandwidth storage is made possible using
Fibre Channel Arbitrated Loop (FC-AL) technology. The PFR500’s modular,
scalable design provides additional disk storage as your needs increase.
Feature highlights:
•Ten drives in a 3U vertical rack space
•No single point of failure
•All active components are hot-serviceable
•Scalable expansion using PFR500E RAID Expansion Chassis
•Optional dual RAID controllers provide Fibre Channel failover
•Copper Fibre Channel interface (GBIC)
The PFR500 utilizes dual FC-AL technology, allowing two loop configurations
within a single chassis. Port-Bypass Circuits have been added to maintain loop
integrity during failures without user intervention. Each loop and associated Port
Bypass Circuits along with all other activecomponents are onredundant, separate hot
2359

Chapter 1 About the PFR500/E
16 PFR500/E Instruction Manual 20 September 2002
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 PFR500 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 one3U highrack-mountablechassis.The PFR500 currently uses73GB
or 180GB drive capacities. With ten drives, one chassis holds up to 730GB or 1.8TB
depending on the disk drive option.
The PFR500E RAID Expansion Chassis provides additional storage capacity. It is an
identical chassis with two Loop Bypass Board installed. Up to nine PFR500E 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 PFR500/E is used to refer to either the PFR500 or
the PFR500E interchangeably.
PFR500/E components
The PFR500/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
modulesare hot-swappablefield replaceable units (FRUs), which means you can add
or replace them while the PFR500/E is powered up.
An optional second RAID Controller Module in the PFR500, allows for continued
access to the PFR500 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:HotswappingtheRAIDController or LBBmodules(removingorinserting)
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.

PFR500/E components
20 September 2002 PFR500/E Instruction Manual 17
NOTE: Every PFR500/E RAID controller includes a backup battery so that if
electrical power is lost,data stored in cache memory will be saved. Data store cache
is not used in the PFR500/E, so the Battery Backup module is not used, even
though it ships as part of the LBB module.

Chassis
The chassis is a sheet-metal housing which contains a passive midplane and chassis
slots for the RAID Controllers, or Loop Bypass Boards, disk drives, power supplies,
and the fan modules.
Each chassis includes a chassis address switch on the midplane board that must be set
to a unique address 0 through 9 during installation. Refer to your PVS Series
InstallationGuide or the Media Area NetworkInstallation Manual for information on
setting the chassis address switch depending how the PFR500 is used. See also,
“Chassis address setting requirement”on page 26.
The following diagram shows how disk modules are identified based on the chassis
address and physical location. The chassis with an address set to 0 contains drives
from 0 to 9; the chassis with an address set to 1 contains drives from 10 to 19; and so
forth.
Midplane
The midplane distributes power and signals to all the chassis components. All FRUs
plug directly into midplane connectors. The midplane includes a chassis address
switch that must be set during installation. Refer to “Chassis address setting
requirement”on page 26 for information on setting the chassis address.

Disk modules
20 September 2002 PFR500/E Instruction Manual 19
Disk modules
Each disk module consists of a Fibre Channel disk drive in a carrier assembly. If a
disk drive fails, and needs replacing, you can do so while the PFR500/E is powered
up. Replacement disk drives take 3-4 minutes to begin rebuild after being installed.
(See “Removing and installing disk modules”on page 40.)
The disk drives are 3.5-inch FC-AL drives that conform to the Fibre Channel
Arbitrated Loop (FC-AL) standards and support dual-port FC-AL interconnects
through the two RAID controllers and their cabling.
CAUTION: Once the PFR500/E is installed and configured, the disk modules
become slot dependent. Moving disk modules between physical slots will result in
loss of data and the need to reconfigure the system.

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.
PFR500E RAID Expansion Chassis circuit board modules
PFR500E RAID Expansion Chassis always has two LBB modules installed as shown
in the following figure. This provides two internal Fibre Channel loops for the disk
modules.At power-up,odd numbered disk drivesare supported by theLBB inthe ‘A’
slot, while even numbered disk drives are supported by the LBB in the ‘B’slot. In the
event of an LBB module failure, the faulty loop is bypassed and all disk drives
failover to the remaining LBB module. The LBBs are clearly labeled “A”or “B”on
the rear panel of the canister.
The LBB in the PFR500E has two Fibre Channel ports: the Left and Right Fibre
Channel Loop Ports. Copper GBICs (Gigabit Interface Converter) are used in these
ports to connect Fibre Channel cabling to a PFR500 or PFR500E. This extends the
Fibre Channel loop of the corresponding PFR500/E chassis. There is a port status
LED for each Fibre Channel port. Refer to “Interpreting rear panel status LEDs”on
page 38.
