1.1 Product Description
The RAID Array 3000 Controller Shelf (Figure 1–1) is a rackmount storage system containing the basic components required to manage a storage array with
two 16-bit, differential, UltraSCSI bus host interfaces. The devices, referred to as
StorageWorks Building Blocks or SBBs, are di sk drives from t he Storage W orks
family of storage devices. The release note that accompanies the storage system
lists the software solutions and disk drives tha t are supporte d.
The Controller Shelf is connected to one or multiple (up to four) 6-slot Device
Expansion Shelves (shown in Figure 1–2) to form the complete RAID Array
3000 storage system. The expansion shelf is offered as an option with a minimum of one shelf required. It contains six SBB slots for the disk drives, two
power supplies, and a personality I/O module that connects the SCSI interface
with the controller shelf. The Device Expansion Shelf is supported by its own
user’s guide (Part No.: EK–BA356–UG) which must be used in conjunction with
this document to properly install and configure your storage system.

NOTE
The Device Expansion Shelf (DS-SWXRA-GN)
must have a revision level of B01 (or higher) to
operate wit h the RAID Array 3000 Controller Shelf.
Also, the Personal ity I/O m odule suppl ied with t he
shelf (part no. 70-33067-02) must have a minimum revision lev el of H01 or higher.
The Controller Shelf and the accompanying Device Expansion Shelves are installed in a standard RETMA or metric rackmount cabinet design. The Device
Expansion Shelves are typically mounted directly above the Controller Shelf in
the cabinet. Each shelf is supplied with a bracket mounting kit to secure the unit
into the desired cabinet design. The bracket kit for a metric cabinet is optional
and must be ordered separately.

A battery-backup subsystem is included with the Controller Shelf in the form of
a rackmount UPS (Unint e rrupt ab le Powe r Suppl y). In c a se of a powe r f ailure, the
UPS provides temporary power to the storage system while it flushes its cache
contents to di sks. The UPS is normally installed in the lowest available slot in
the cabinet.
CAUTION
The UPS is si zed to perform this funct ion for the
Controller and Device Expansion Shelves only. No
other elec tr i cal dev ic es shoul d be pl ugged int o the
UPS.
As an option, a second RAID controller module can be added for redundancy.
The second controller operates in conjunction with the installed controller to
protect data in case of a malfunction in the primary unit. The optional controller
is installed directly below the primary controller in the center of the shelf.
The RAID Array 3000 Controller Shelf enclosure and its associated options are
listed and described in T a ble 1–1.

1.3 Controller Shelf Enclosure
The Controller Shelf is housed in an rack-mount enclosure. It has two power
supplies, a single RAID Array controller, an empty slot for a second (redundant)
controller, two host I/O assemblies, and a dual-bus device I/O assembly. Two
blowers located at the back of the enclosure cool the shelf.
An internal backplane assembly connects the RAID controller and the power and
host I/O SBBs. The backplane contains five connectors which provide the interface between the Shelf SBBs and the controller. Two 300-pin connectors located
in the center of the backplane provide the controller interface. The backplane
connection to the blowers is made through two separate 9-pin female connectors,
one for each blower.
The backplane also contains a complement of circuit components that provide
SCSI bus termination, blower fail/safe circuits, UPS power sense circuit, shelf
status and dc power monitoring, and a speaker alarm circuit with an operator
controlled alarm disable switch. The outputs of the shelf status and dc power
monitoring circuits are connected to two LED indicators on the front panel of the
shelf to notify the operator during a malfunction. The alarm disable switch allows the operator to turn off the audible alarm if desired.

1.4 Shelf Cabinet Installation
The Controller Shelf can be mounted in a StorageWorks metric or RETMA style
cabinet. You must install the appropriate shelf rail kit hardware to properly
mount the shelf in the cabinet. The RETMA rail kit is supplied with the shelf and
contains the installation guide which describes the installation procedure. The
rail kit for a metric cabinet is optional.
The commercial UPS supplied with the Controller Shelf is installed in the cabinet using a special mounting bracket designed to accommodate either a metric or
RETMA style cabinet. The bracket has two sets of mounting holes at each end
which allows its installation into either cabinet.

RAID Array 3000 Controller Shelf
The controller supports one (for a single controller) or two (for dual-controllers)
standard 72-pin cache SIMMs of up to 64 MB . I n a d ual-cont r oller setup, both
controllers must have identical cache configurations and the total usable cache
(per controller) will be half the amount installed due to mirroring. Thus, in a single controller setup the maximum usable cache is 128 MB while a redundant
setup has a maximum usable cache of 64 MB (per controller).

the module the two-spring steel mounting tabs expand and engage the shelf. The
combination of the mounting tabs and the backplane connector ensures that the
module is firmly seated.
The front edge of the internal circuit board in the device I/O module contains
two-blower status LEDs (see Figure 1–6). Under normal operating conditions,
the LEDs are ON. When there is a blower error or an over-temperature condition,
they are FL ASHING. T h e uppe r L E D displ a y s t he status of the left blower and
the lower LED displays the status of the right blower. The blowers cool the device I/O module by drawing air in through the slots in the front and exhausting it
out the rear of the shelf. Re fe r to t he Storage W orks SBB Shelf I/O Module

nectors and two 9-pin D connectors. The SCSI connectors provide the SCSI bus
connections between the adapter in the host system and the controller(s) in the
Shelf. One of the 9-pin D connectors interfaces the UPS status signals to the
controller. The other provides a serial connection between its respective controller, the Shelf, and the SWCC configuration/maintenance PC.
The high-density SCSI connectors on the Host I/O module are designated Host In
(bottom connector) and Ho st Ou t (t op c onnec t or). Ho st I n provi de s the SCSI
connection for a one-to-four expansion shelf cabinet installation. Cable connections to multiple storage shelves are made through Trilink adapters.
In addition to the front panel connectors, the Host I/O module contains three passive differential SCSI bus terminators that terminate the SCSI bus from the host
system. Termination is automatically disabled when a cable is connected to the
Host Out co n nector. T h e UPS se r ial connector on the host I/O module (designated CTR 0 and CTR 1) provides shelf status information to the UPS.
NOTE
If you have onl y one SCSI c able c onnec ti on to t he

1.5.4 Shelf Cooling
The device I/O module ensures that the SBBs and Controller Shelf are at the
proper operating temperature by monitoring the operational status of the blowers
and sensing the ambient air temperature.
The two dual-speed blowers cool all the shelf components by drawing ambient
air in through the front of the SBBs and exha usting i t out t he rea r of t he Controller Shelf. The blowers normally operate at low speed. Reduction of the airflow through the shelf or an increase in the ambient temperature may result in
overheating causing component failure or data corruption.
The device I/O module ambient temperature circuitry monitors the air flowing
through the module. If the ambient temperature exceeds 32ºC + 2º C, the circuitry:
Turns on both blower LEDs
•
Causes both blowers to switch to the high-speed mode to increase air flow
•
through the shelf
When the I/O module circuitry detects a blower that is not operating or not operating at the correct RPM, this circuitry:
Turns ON a LED on the I/O module front panel that identifies the defective
•
blower
Causes the operational blower to switch to the high-speed mode to increase
•
air flow through the shelf, thereby maintaining the proper operating environment
NOTE
The Controller Shelf power supply status LEDs
also display blower error conditions. However,
they do not identify the defective blower, nor do
they report ambient air temperature faults.
1.5.5 Controller Shelf Power Supplies
The Controller Shelf has two interchangeable, air-cooled, 180 watt AC power
supply SBBs (see Figure 1–8) located at the left two SBB slots of the shelf. The
power supplies provide redundant power if one of the units should malfunction.
Each supply provides +5 and +12 Vdc to power the RAID controller(s), the host
I/O modules, the device I/O module, and the blowers. The first power supply
from the left edge of the shelf is designated as "A" and the second as "B". The
SBB front panel has an ac input power receptacle, a power supply status LED,
and a shelf status LED.

1.5.6 Uninterruptable Power Supply (UPS)
The pri m ary funct i o n of t h e UPS is to keep t h e entire storage sys tem powered-up
to enable the controller(s) to flush cache to disks. The UPS also protects the storage system from problems associated with poor quality AC power or a complete
loss of AC power. The UPS i s normally mounted in a lower shelf slot in the
cabinet using a custom set of mounting brackets.
The ma j o r features o f t h e UPS i n c lude Battery Management Technology (doubles battery life and speeds recharge time), hot-swap batteries to simplify service, voltage regulation, power control which enables scheduled shutdowns and
maximized run time, and network surge protection.
The front panel display ha s user cont rols (LE Ds and cont rol but t ons) and the re ar
panel contains an RS-232 COMM port which provides UPS status to the electronics in the Controller Shelf. The rear panel also contains the network surge
protector, and four power receptacles. An audible alarm is activated when input
power fails, as a low battery warning, or whenever the UPS is in need of se r v i c ing. The front panel control switches are used to set the output voltage level and
battery low-warning option.
The UPS automatically recharges its battery when power is returned following a
power failure. Recharge time is less than four hours depending on the energy requirements of your load and the length of the power outage.
Its own installation, operation, and service manual support the UPS. The manua l
describ e s the UPS in detail and is part of the documentation set enclosed with
your storage system.
