About the PFC500/E
This chapter introduces the Profile XP Fibre Channel RAID Storage Chassis. Topics are :
• PFC500/E components
• Enclosure
• RAID Controllers (RCs)
• Disk modules
• Power supplies
• Drive fan pack
• Configurations
The PFC 500 is an intelligent, highly available, high performance, high capacity storage system that uses a Fibre Channel Arbitrated Loop (FC-AL) as its interconnect interface. Its modular, scalable design provides additional disk storage as your needs increase.
Using its FC-AL interface, with simple FC-AL serial cabling, an PFC500 can support up to two PFC500E RAID Expansion Chassis. A PFC500E is a basic chassis without a RAID controller (RC). The PFC 500 and two PFC 500Es support up to 30 disk modules in a single disk-array storage system. You can place the PFC 500Es in the same cabinet as the PFC500, in a separate cabinet, or in two separate cabinets.
An PFC500 connects to a Profile XP Media Platform using the server’s Fibre Channel
Disk adapter (FC adapter).
Throughout this manual, the term PFC 500/E is used to refer to either the PFC500 or the PFC500E interchangeably.
2 December 1999 PFC 500/E Instruction Manual 17
Chapter 1 About the PFC500/E
PFC500/E components
The PFC 500/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 controller, disk module, or power supply) has a filler module to maintain air flow and compliance with electromagnetic interference (EMI) standards.
The RCs, disk modules, power supplies, fan packs, and filler modules are customer-replaceable units (CRUs), which you can add or replace without tools 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 provides continued access to the PFC500 and any connected PFC500Es if the first RC fails. Adding a second RC to the same chassis is not intended to increase performance, but rather to add redundancy .
Refer to the Profile XP System Guide for detailed connection, configuration, and performance information.
The disk drives are FC-AL compliant and support 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 components, 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.
Component
RAID Controller
Power supply
Name in slot A
RC A

Front door
Front door
Locking latch with key
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 PFC 500 from a PFC 500E . An RC is a printed-circuit board with one dual in-line memory module (DIMM), a bezel with status lights, and securing latches.
E X P
B expansion (EXP) port port B port A serial connection
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 is called the RC front end. 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 card
(LCC) in the PFC500E chassis. This FC-AL is referred to as the RC back end.
An RC also has an RJ-type connector for serial communications with a console.
2 December 1999 PFC 500/E Instruction Manual 21
Chapter 1 About the PFC500/E
Each RC has two status lights visible from the rear of the PFC500/E. For the meaning
of these lights, see “Monitoring PFC500/E status” on page 40.
Storage-system 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 are installed, you can replace either RC while the PFC 500 is running. You should never attempt to replace any of the RC’s components, except the memory modules.
Disk modules
Carrier
Shock mount (4)
Disk drive
Latch
Handle
ESD clip (2)
Each disk module consists of a Fibre Channel disk drive in a carrier assembly. You can add or remove a disk module while the PFC 500/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 Attach (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 can combine approved drives of either height, and from different manufacturers, within the same PFC500/E, subject to the restrictions imposed by the Licensed Internal Code (LIC) running in the PFC 500’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 discharge (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.

The power supplies are located 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-factor-corrected, multi-output, off-line converter with its own line cord and on/off switch. Each supply supports a fully configured PFC 500 and shares load currents with the other supply, if it is present. The drive voltage lines have individual soft-start switches that protect the disk drives if you install them while the PFC 500/E is powered up. A disk with power-related faults will not adversely affect the operation of any other disk.
Each power supply has status lights. These status lights are partially visible through the drive fan pack, and fully visible with the drive fan pack removed. The status lights
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 PFC500/E while the PFC 500/E is powered up.

The drive fan pack cools the disk modules and RCs in the PFC500. The drive fan pack contains three fans that draw ambient room air through the front door, across the drive modules, and through the midplane and power supplies. The drive fan pack connects directly to both power supplies, and either supply can power it. The fans operate at a lower voltage and speed during normal operation to minimize acoustic noise. If a fan fails, the voltage and speed of the remaining fans increase to compensate, resulting in higher acoustic noise.
One status light on the drive fan pack indicates status. The status light is described in the “Monitoring PFC 500 status” section of Chapter 3.
Latches on the drive fan pack hold the pack in place.
IMPORTANT: You can remove the drive 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 modules 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.

To determine a PFC 500/E’s power requirements, use the power rating on the chassis label. This rating is the maximum power required for a fully loaded chassis. The input current, power (VA), and dissipation for the PFC500/E are based on the maximum capability of the power supplies and cooling system to provide internally regulated power. Typical values will be less depending on the number and manufacturer of disk drives and activity level. These values represent either the values for the power cord of an PFC500/E with a single power supply, or the total values shared by the line cords of two power supplies in the same PFC500/E, with the division between the power cords and supplies at the current sharing ratio. If one of the two power supplies fails, the remaining supply and cord support the full load. You must use a rack mount cabinet with ac power distribution, and have main branch ac distribution that can handle these values for the number of PFC500s and PFC 500Es that you will interconnect.
Cooling
The ambient temperature specification is measured at the front door inlet. The site must have air conditioning of the correct size and placement to maintain the specified ambient temperature range. The air conditioning must be able to handle the BTU requirements of the PFC500s and any connected PFC 500Es.
2 December 1999 PFC 500/E Instruction Manual 25
Chapter 2 Installing a PFC500/E
Cabling requirements
You mst use copper cables for the FC-AL connections between the RCs and the server adapters or hubs. You should use a common ground distribution grid for all interconnected devices.
IMPORTANT: You must use a copper cable only (not an optical cable) to connect a PFC500 to a PFC500E.
Any copper cables you use must meet the appropriate standards for 1-Gbaud FC-AL loops. Such cables are fully shielded, twin-axial, full-duplex cables with DB-9 connectors. Cables greater than 10 meters must be equalized; cables equal to or less than
10 meters do not need to be equalized.
PFC500 and PFC 500E interconnections should maintain LCC consistency. That is, one
FC loop should connect the PFC500’s RC A and each PFC500E’s LCC A. The other FC loop should connect the PFC 500/E’s RC B and each PFC500E’s LCC B.
Do not leave an unused (that is, dangling) cable connected to an RC port because it may cause excess noise on the loop.
Addressing requirements
There are two addresses for the PFC500: the Fibre Channel Arbitrated Loop address ID
(FC-AL address ID) and the chassis address.
FC-AL address ID
Each node (such as an RC) on the Fibre Channel front-end loop must have a unique
FC-AL address ID. The FC-AL protocol translates the FC-AL address ID into an 8-bit arbitrated loop physical address (ALPA). You set the RC FC-AL address ID using switches, as explained later in this chapter. If your PFC500 has a second, redundant RC, it should be set to the same FC-AL address ID as the primary FC.
Chassis address (CA)
Each PFC500 and PFC500E on a back-end loop needs a unique chassis address (CA) that identifies the chassis and determines disk module addresses. The PFC500 must have an CA of 0. You must set that CA using the chassis address switches, as explained later in this chapter. If you cable any PFC500Es to the PFC500, you might want to set the nearest PFC 500E’s CA to 1, and the next to 2. The chassis address is displayed in lights visible behind the front door.
26 PFC 500/E Instruction Manual 2 December 1999
Installing a PFC500/E in a cabinet
Installing a PFC500/E in a cabinet
The cabinet in which you will install the PFC500/E(s) must have a full earth ground to provide reliable grounding. Also, the cabinet should have its own switchable power distribution. If any PFC 500/E you will install has two power supplies, we suggest that you use a cabinet that has dual power distribution units, one on each side.
>>> WARNING: The rack mount PFC500/E is heavy and should be installed into a rack by two people. To avoid personal injury and/or damage to the equipment, do not attempt to lift and install the PFC500/E into a rack without help from another person.
We recommend that you use cabinet anti-tip devices, especially if you are installing or removing a PFC 500/E in the upper half of the cabinet when the lower half is empty.
You install each PFC500/E on two L-shaped mounting rails connected to the cabinet’s vertical channels. The PFC500/E mounting rails attach to the cabinet only, and do not have components which attach to the RAID chassis.
Rack-mounting the PFC 500/E chassis consists of:
1. Determining the rail mounting positions in the cabinet.
2. Attaching the mounting rails to the cabinet.
3. Sliding the PFC500/E chassis onto the mounting rails.
4. Setting addresses and connecting cables.
The following sections describe these operations.
Determining the rail mounting positions
The following table lists the heights of the PFC500 and the PFC500E. Use these measurements to determine the position of your RAID devices in your cabinet.

NOTE: Because the RAID storage units are each 3.5 U high, a 0.5 U open space is created if you install one of these units immediately below your Profile XP Media
Platform. You can fill this gap with a 1/2 U filler, which attaches to the chassis, not to the cabinet channels.

The PFC 500 and any PFC500Es in the cabinet will power up.
PFC500/E powerup and initialization
The only power switches on a PFC500/E are those on the power supply, which are normally covered by the drive fan pack. As a result, a PFC500/E is always active.
When ac power is initially applied to a PFC 500/E, the disk drives power up according to their specifications, and spin up in a specified sequence. The slot spin-up delays are multiples of 12 seconds. The maximum delay is 84 seconds. The same delays are used when you insert a drive while an PFC500/E is powered up.
NOTE: Upon powerup, all LUNs are controlled by RAID Controller A if it is operational. RC B controls LUNs only if RC A fails, and continues to control LUNs until the next powerup.
PFC500/E powerdown
To turn off power correctly
1. Stop any I/O activity to the PFC 500/E.
2. Shut off power to the ac distribution strips that supply the PFC500/E.
The power in the distribution strips may be controlled by a circuit breaker located inside the cabinet (if the cabinet has such breakers) or may be controlled by a circuit breaker located externally to the cabinet.
To turn on power, reverse the steps to powerup the PFC500/E.
Binding disk modules into groups
After cabling an PFC500/E and any PFC 500Es, you must bind disk modules into LUNs and create a file system using the Profile XP Disk Utility. Refer to the Profile XP System
Guide for more information on configuring your storage system.

Chapter 3 Servicing and upgrading a PFC 500/E
Handling CRUs
This section describes the precautions that you must take and the general procedures you must follow when removing, installing, and storing CRUs.
Power issues and CRUs
The PFC500/E is designed for continuous operation and to be hot repairable. It should always be powered up. You should replace any disk module, redundant RC, redundant power supply, or the fan pack while the PFC 500/E is running.
Its front door should be closed and each of its compartments should contain a CRU or filler panel to ensure EMI compliance and proper air flow over the CRUs.
While the PFC500/E is powered up, you can service or replace any CRU. You should not remove a faulty CRU until you have a replacement available.
IMPORTANT: You can remove the drive fan pack while the PFC500/E is powered up. While the pack is removed, the Cooling check light on the power supply flashes.
If the pack is removed for more than 2 minutes, the disk modules power down and the each RC goes into standby mode. When you reinstall the drive fan pack, the disk modules power up and each RC goes into active mode.
Since you can replace or add any CRU without sliding the PFC500/E out of the cabinet, you do not have to use cabinet anti-tip devices when you upgrade or service an PFC 500/E.
If you need to power down an PFC 500/E, refer to the power down procedure on
Avoiding electrostatic discharge (ESD) damage
When you replace or install CRUs, you can inadvertently damage the sensitive electronic circuits in the equipment by simply touching them. Electrostatic charge that has accumulated on your body discharges through the circuits. If the air in the work area is very dry, running a humidifier in the work area will help decrease the risk of
ESD damage. You must follow the procedures below to prevent damage to the equipment.
IMPORTANT: Read and understand the following instructions.
• Provide enough room to work on the equipment. Clear the work site of any unnecessary materials or materials that naturally build up electrostatic charge, such as foam packaging, foam cups, cellophane wrappers, and similar items.
• Do not remove replacement or upgrade CRUs from their antistatic packaging until you are ready to install them.
• Gather together the ESD kit and all other materials you will need before you service an PFC500/E. Once servicing begins, you should avoid moving away from the work site; otherwise, you may build up an electrostatic charge.
• Use the ESD kit when handling any CRU. If an emergency arises and the ESD kit is not available, follow the procedures in the “Emergency procedures (without an
ESD kit)” section.
42 PFC 500/E Instruction Manual 2 December 1999
Precautions when removing, installing, or storing
• To use an ESD wristband , attach the clip of the ESD wristband (strap) to any bare
(unpainted) metal on the PFC500/E chassis; then put the wristband around your wrist with the metal button against your skin.
Emergency procedures (without an ESD kit)
In an emergency when an ESD kit is not available, use the following procedures to reduce the possibility of an electrostatic discharge by ensuring that your body and the subassembly are at the same electrostatic potential.
IMPORTANT: These procedures are not a substitute for the use of an ESD kit.
Follow them only in the event of an emergency.
• Before touching any CRU, touch a bare (unpainted) metal surface of the cabinet or chassis.
• Before removing any CRU from its antistatic bag, place one hand firmly on a bare metal surface of the chassis, and at the same time, pick up the CRU while it is still sealed in the antistatic bag. Once you have done this, do not move around the room or contact other furnishings, personnel, or surfaces until you have installed the
CRU.
• When you remove a CRU from the antistatic bag, avoid touching any electronic components and circuits on it.
• If you must move around the room or touch other surfaces before installing a CRU, first place the CRU back in the antistatic bag. When you are ready again to install the CRU, repeat these procedures.
Precautions when removing, installing, or storing CRUs
Use the precautions listed below when you remove, handle, or store CRUs.
• Do not remove a faulty CRU until you have a replacement available.
• Handle a CRU only when using an ESD wristband as follows: attach the clip of the
ESD wristband to the ESD bracket or bare metal on the PFC 500/E chassis, and put the wristband around your wrist with the metal button against your skin.
• Handle CRUs gently. A sudden jar, drop, or vibration can permanently damage a
CRU.
• Never use excessive force to remove or install a CRU.
• Store a CRU in the anti-static bag and specially designed shipping container in which you received it. Use that container if you need to return the CRU for repair.
• Maintain the location where you store CRUs within the limits specified in
Appendix A.

Chapter 3 Servicing and upgrading a PFC 500/E
Replacing or adding a disk module
>>> CAUTION: You can destroy a storage system beyond recovery if you move the wrong drive. The system operator or service person can move a disk module with the following cautions:
• The disk module must be unbound.
• Moving a module that is part of a LUN to another slot makes all information on the
LUN inaccessible.
• You must remove and install the disk module while the storage system is powered up.
A disk module must be inserted all the way or removed entirely. Do not leave a disk module partially removed except for periods when you are allowing it to spin down.
A disk module being inserted or removed may be damaged by a partially removed adjacent module.
When replacing multiple disks, observe the following:
• After removing a disk module, wait for the activity lights on the other disk modules to resume a steady flicker before removing the next module. The activity lights show that the LIC (licensed internal code) has rediscovered the FC loop.
• After inserting a disk module, wait for the activity lights on the other drives to resume a steady flicker before inserting the next module. As with module removal, the activity lights show that the LIC has rediscovered the FC loop.
>>> CAUTION: Handle a disk module gently and use an ESD wristband. Do not remove a faulty disk module until you have a replacement module (with the same part number) or a filler module available. The part number appears on the top or bottom of the module. A replacement or add-on disk module should have the same format
(520- or 512-byte sectors) and the same capacity as the other modules in the chassis.
IMPORTANT: You must open the PFC 500/E’s front door to access the disk modules. The door must be closed for EMI compliance when the PFC500/E is powered up. Open it only to replace or add a disk module.

Chapter 3 Servicing and upgrading a PFC 500/E
Installing an RC or an RC filler module
IMPORTANT: If you are installing a new/add-on/replacement RC, ensure that the
RC memory has been installed before proceeding to install the RC.
Each RC requires a unique FC-AL address ID on the loop to communicate with the
Profile XP Media Platform. If you are installing a replacement RC, set its address to be the same as that of the RC you removed. If you are installing an add-on RC, set the address to a different setting than the address of any other RC on the loop. The FC-AL protocol translates the FC-AL address ID into an 8-bit arbitrated loop physical address
(ALPA).
IMPORTANT: Each RC’s FC-AL ID must be unique on the FC-AL loop. If you have two FC-AL loops, we suggest a unique FC-AL address ID for each RC on both loops.
The valid FC-AL address ID range is a number 0 through 125 decimal, which is 0 through 7D hexadecimal. The following figures and table locate the switches and show how to select ID numbers using them.
IMPORTANT: You must set the FC-AL address ID on the RC before you install it.
If you are installing an RC filler module, ignore step 1 and proceed to step 2 on the next page.
1. Using the RC FC-AL ID switches, set the FC-AL address ID as shown below.

Technical specifications
Technical specifications include power requirement, size, drive, interface, and standards information.
ac power requirements
The input current, power (VA), and dissipation per PFC500/E are based on the maximum capability of the power supplies and cooling system to provide internal regulated power. Typical values will be less, depending on the number and manufacturer of disk modules. These values represent either
• the values for the line cord of an PFC500/E with a single power supply, or
• the total values shared by the line cords of two power supplies in the same iDAE, with the division between the line cords and supplies at the current sharing ratio.
A failure of one of the two power supplies in the iDAE results in the remaining supply and cord supporting the full load. You must use a rackmount cabinet with ac power distribution, and have main branch ac distribution that can handle these values for each iDAE in the cabinet.

Glossary
The terms and definitions listed below are related to the storage system described in this manual. Understanding them will aid your understanding of the storage system.
ALPA (arbitrated loop physical address) — An 8-bit address that uniquely identifies a device on an FC loop.
bind — In the context of a disk-array storage system, the procedure by which you hardware-format one or more disk modules into one LUN (logical unit) - usually as one of several types of RAID group.
BTU (British Thermal Unit) — A standard measure of a device’s heat output.
cache — See storage-system caching.
CA (chassis address) — A number, selectable on a PFC 500/E front panel, set to 0 on an PFC500, that helps establish a unique address for each disk module on an
FC-AL loop. You must set the CA on each RAID Expansion Chassis (PFC 500E).
Since the PFC500 CA is 0, you might set the first PFC500E CA to 1 and the second to 2.
CRU (customer-replaceable unit) — A hardware component, like a disk module, that anyone can install or replace.
disk-drive module — Another name for disk module.
disk unit — A short name for physical disk unit.
disk module — A self-contained disk drive that slides into one of the slots in the front of the storage system. It consists of the carrier assembly, which holds the disk drive and the regulator board. Also called disk-drive module.
DIMM (dual in-line memory module) — A type of memory module used in RC memory for write caching or RAID 3 memory.
EMI (electromagnetic interference) — Electronic radiation emitted by an electrical device. The levels of EMI are strictly controlled for data processing equipment. The
EMI standards are explained after the Notice page near the beginning of the manual.
ESD (electrostatic discharge) — The discharge of an accumulated electrical charge
(static). This can severely damage delicate electronic circuits and you should take
steps to prevent this, as explained in the Chapter 3, “Servicing and upgrading a
FC-AL (Fibre Channel arbitrated loop) — An arrangement of Fibre Channel stations such that messages pass from one to the next in a ring.
FC-AL address ID — A number that identifies a device as a node on a fibre channel loop. You select the FC-AL address ID for an SP using switches on the RC. The
2 December 1999 PFC 500/E Instruction Manual 71
default FC-AL address ID for RC A is 0; the default FC-AL address ID for RC B is
1.
Fibre Channel Disk board — The name for the printed-circuit board within the
Profile XP Media Platform that allows the server to access the Fibre Channel loop and thence the disk drives within a PFC500/E.
field-replaceable unit — See FRU (field-replaceable unit).
FRU (field-replaceable unit) — A hardware assembly that can be replaced on site, instead of at the point of manufacture.
hot repair — See replace under power.
hub — An FC_AL switching device that allows multiple servers and targets such as storage systems to connect at a central point. A single hub configuration appears as a single loop.
LCC (link control card) — A CRU in an enclosure that connects Fibre Channel signalling to the disk modules. The LCC receives and electrically terminates the incoming FC-AL signal. Then it passes the input signal to the disk drives in the
PFC500E, and drives the output signal via cables to the next device (if any) in the loop.
LUN (logical unit) — One or more disk modules (each having a head assembly and spindle) bound into a group - usually a RAID group. The operating system sees the
LUN, which includes one or more disk modules, as one contiguous span of disk space.
media interface adapter — See MIA (media interface adapter).
memory module — See RC memory module.
MIA (media interface adapter) — A device for connecting an optical cable to a
DB9 copper connector.
node — Any device with a Fibre Channel interface that connects to a Fibre Channel loop.
power supply — An essential element of the storage-system power supply. A storage system can have two power supplies, PS A and PS B. With two, it can survive failure of one supply. You can replace a power supply under power, without interrupting applications.
PFC 500 RAID Expansion Chassis — A storage system that includes a chassis, up to 10 disk modules, one or two RCs, and one or two power supplies. A PFC500 can support up to two PFC 500E RAID Expansion Chassis (each with up to 10 disk modules) in addition to its own 10 disk modules, for a total of 30 disk modules.
PFC 500E RAID Storage Chassis — A storage system that includes a chassis, up to
10 disk modules, one or two LCCs, and one or two power supplies.

PLDA (private loop direct attach) profile — A standard for FC-AL disk drives.
RAID controller (RC) — See RC (RAID controller).
RC (RAID controller) — A printed-circuit board with memory modules and control logic that manages the storage-system I/O between the Profile XP Media Platform
FC adapter and the disk modules. The RC in a PFC500/E storage system sends the multiplexed fibre channel loop traffic through a link control card (LCC) to the disk units. For higher availability, a PFC500 can use a second RC.
RC memory module — A memory module (DIMM or SIMM) that provides the local storage for an RC.
replace under power — The storage system provides replace under power capability, allowing you to replace, for example, a disk module or a fan module without powering down the storage system. Applications continue while you replace the failed module.
SCSI (small computer system interface) — A well-known protocol and standard for connecting computers and peripheral devices.
SES (SCSI enclosure services) — A functional subset of SCSI III commands that allow a server to communicate with storage enclosures using their disk modules.
SFF — Small Form Factor Committee
server — In the context of storage systems, a processor that runs an operating system and uses a disk-array storage system for data storage and retrieval.
storage chassis — A storage device that includes a chassis, up to 10 disk modules, one or two Fibre Channel LCCs, and one or two power supplies.
storage-system caching — The procedure of storing disk-based data in RAM memory (in this case, DIMM memory on an RC) temporarily to save time if the data needs to be accessed or changed again soon.
