Chapter
1
About the PFC500/E
This chapter introduces the Profile XP Fibre Channel RAID Storage Chassis. Topics
are :
• PFC 500/E components
•Enclosure
• RAID Contro ll ers (RC s )
• Disk modules
• Power supplies
• Drive fan pack
• Configurations
The PFC500 is an intelligent, highly avail able, high performance, high capacity
storage system tha t uses a Fibre Channel Ar bitrated Loop (FC- AL) as its inter connect
interface. Its modular, s cala ble design provides additional disk storage as yo ur needs
increase.
Using its FC-AL int erface, with simple FC-AL s erial cablin g, an PFC500 can support
up to two PFC500E RAID Expansion Chassis. A PFC500E is a basic chassis without
a RAID controller (RC). The PFC500 and two PFC 500Es support up to 30 disk
modules in a single disk-arr ay storage system. You can place the PFC500Es in the
same cabinet as the PFC500, in a separate cabinet, or in two separate cabinets.
An PFC500 connects to a Profile XP Media Platfor m using the server’s Fi bre Channel
Disk adapter (F C ad ap ter).
Throughout this m anual, the term PFC500/E is used to refer to either the PFC500 or
the PFC500E interchangeably.
Chapter 1 About the PFC500/E
18 PFC 500/E Instruction Manual 2 December 1999
PFC500/ E components
The PFC500/E components are:
• A sheet-metal chassis with a midplane and front door
• One or two RAID controllers (PFC500 only)
• One or two Link Control cards (PFC500E only)
• As many as ten Fibre Channel disk modules
• One or two power supplies
• One drive fan pack
Any unoccupied slot (RAID control ler, disk module, or power supply) has a filler
module to maintain ai r flow and compliance with e lectromagnetic interference (E MI)
standards.
The RCs, disk modules, power supplies, fan packs, and filler modules are
customer-replaceable units (CRUs), which you can a dd or repl ace without t ools while
the PFC500/E is powered up.
The optional high availability features for an PFC500/E are
• second RC (PFC500 only)
• second power supply
A second RC p rovides conti nued access to the P FC500 and any connec ted PFC500Es
if the first RC fail s. Adding a second RC to the same chassis is not int ended to increase
performance, but rather to add red undancy
. Refer to the Profile XP System Guide for
detailed connecti on, configuration, and performance information.
The disk drives are FC-AL compliant and suppor t dual-port FC-AL interconnects
through the two RCs and their cabling.
Chassis
The chassis is a sheet-metal housing with a front panel, a midplane, front door, and
slots for the RCs, disk modules, power supplies, and the fan pack.
The following figures show the PFC500/E components. Details on each component
follow the figures. If the chassis provides slots for two identical c omponents, the
component in slot A is called component-name A. If there is a second component, it
is in slot B and is called component-nameB, as follows.
If you have one power supply, it can be in either slot A or slot B. If you have one
RAID controller, it can be in either slot A or B.

module slot, and two status lights. All lights are visible with the front door closed.
The chassis address light displays the chassis address setting for the PFC500. The
PFC 500 must have an CA of 0. You must set that CA using the chassis address
switches, as explained in Chapter 2.
The status lights are described in the “Monitoring PFC500/E status” on page 40.
Midplane
The midplane di stributes power and signals to all the c hassis components. All CRUs
except the fan packs plug directly into midplane connectors.

Front door
2 December 1999 PFC 500/E Instructi on Manual 21
Front door
The front door has a locking latch and an EMI shield. The latch is a push button with
a removable locking key that you can use in any PFC500 or PFC500E. When the door
is open, you can remove or install disk modules.
IMPORTANT: The front door must be closed for the PFC500/E to be EMI
compliant. Opening the door to access the disk modules is a service procedure.
RAID Controllers (RCs)
The RC is the PFC500’s intelligent component. It defines the PFC500 and
differentiates the
PFC500 from a PFC500E. An RC is a printed-circuit board
with one dual in-line me mo ry mo dule (DIM M), a bezel with status lights, and
securin g la tc he s .
The RC has three Fibre Channel ports. Port A and Port B are for connecting to a
Profile XP Media Platform. The expansion connector (EXP) is for connecting to a
PFC500E. The port interface i s called the RC front en d. It can connect to a Profile XP
Media Platform’s Fibre Channel storage board. You set an RC’s FC-AL address ID
using rotary switches.
The RC connects to disk modules in the same chassis via an internal FC-AL. The
expansion port extends the internal FC-AL to the corresponding link control car d
(LCC) in the PFC 500E chassis. This FC-AL is referred to as the RC back end.
An RC also has an RJ-type connector for serial co mmunications with a console.

Chapter 1 About the PFC500/E
22 PFC 500/E Instruction Manual 2 December 1999
Each RC has two status li ghts visible from the rear of the PFC500/E. For the meaning
of these lights, see “Monitoring PFC 500/E status” on page 40.
Storage-syste m read caching requires one RC, and mirrored storage-system write
caching requires two RCs. If an PFC500 has one RC, you can install a second one
while the PFC500 is running. When both RCs ar e installed, you can re place either R C
while the PFC500 is running. You should never attempt to replace any of the RC’s
components, except the memory modules.
Disk modules
Each disk module consists of a Fibre Channel disk drive in a carrier assembly. You
can add or remove a disk module while the PFC500/E is powered up.
Disk drives
The disk drives are 3.5-inch FC-AL drives that conform to the following standards:
• SFF-8045
• Fibre Channel Arbitrated Loop (FC-AL)
• FC-AL Private Loop Direct Atta ch (PLDA) profile
The disk module slots in the chassis accommodate drives with heights of either
1.0 inch (2.54 cm) or 1.6 inches (4.06 cm). You ca n combine approved drives of either
height, and from different manufacturers, within the same PFC500/E, subject to the
restriction s imposed by the Licensed Internal Code (LIC) running in the PFC500’s
RCs.
Drive carrier
The disk-drive carrier is a plastic assembly that slides into the chassis slot guides and
midplane connectors. It has a handle with a latch and electrostatic discha rge (ESD)
clips, which connect to the drive’s head-disk assembly. The latch holds the disk
module in place to ensure proper connection with the midplane.

Power supplies (PSs)
The power supplies are locate d behind the drive fan pack. With two power supplies,
the top supply is installed inverted with respect to the bottom supply.
Each power supply is an auto -ranging, power-fa ctor-cor recte d, multi -output, off-li ne
converter with its own line cord and on/off switch. Each supply supports a fully
configured PF C500 and shares load current s with t he other s upply, if it is present. The
drive voltage lines have individual soft-start switches that protect the disk drives if
you install them wh ile th e PFC500/E is powered up. A dis k wit h power- relate d fault s
will not adversely affe ct the operation of any other disk.
Each power supply has status light s. The se status lights are partially vis ible through
the drive fan pa ck, and fully vi sible with the dr ive fan pack remove d. The status lig hts
are described in the “Monitoring PFC500/E status” on page 40.
A latch on the power supply locks it into place to ensure proper connection to the
midplane. You can add or remove one power supply in a highly available P FC500/E
while the PFC500/E is powered up.

Drive fan pack
The drive f an pack cools the disk modules a nd RCs i n the PFC500. The drive fan pack
contains thre e fans that draw ambient r oom air thr ough the fr ont door, across the dr ive
modules, and through the midplane and power suppl ies. The drive fan pa ck connects
directly to both power supplies, and either supply can power it. The fans operate at a
lower voltage and spe ed during normal operatio n to minimize acoustic noi se. If a fan
fails, the volt age and spee d of t he remai ning fans inc rease to c ompensate, re sulti ng in
higher acoustic noise.
One status light on the driv e fan pack indicat es status. The status li ght is desc ribed in
the “Monitoring PFC500 status” section of Chapter 3.
Latches on the drive fan pack hold the pack in place.
IMPORTANT: You can remove the driv e fan pack while the PFC500 is powered up.
While the pack is removed, the Cooling Check light on each power supply flashes.
If the pack is removed for more than approximately two minutes, the disk module s
power down and the RCs go into standby mode. When you re-install the drive fan
pack, the disk modules power up and the RCs go into active mode.
Configurations
The PFC 500 minimum and maximum configurations are as follows.
The maximum configuratio n provides the mos t redundancy, an d therefore the h ighest
degree of system availability. The fan pack provides redundant cooling for any
configuration.
