CHAPTER
1
Tray Overviews
The Sun StorageTek 2540 Array, the Sun StorageTek 2530 Array, and the Sun
StorageTek 2501 Array are a family of storage products that provide high-capacity,
high-reliability storage in a compact configuration.
The Sun StorageTek 2540 Array is a modular, rackmountable controller tray. It is
scalable from a single dual-controller tray (1x1) configuration to a maximum
configuration of 1x3 with two additional drive expansion trays behind one controller
tray.
All three of the trays can be installed in the following cabinets:
■ Sun Rack 900/1000 cabinet
■ Sun StorageTek Expansion cabinet
■ Any 19-inch wide, 4-post, EIA-compatible rack or cabinet with a front-to-back
depth between vertical cabinet rails of 61 cm to 91 cm (24 in. to 36 in.). The
cabinet can have threaded or unthreaded cabinet rails.
The Sun StorageTek 2540 Array and the Sun StorageTek 2530 Array contain disk
drives for storing data and controllers that provide the interface between a
management and/or data host and the disk drives. The Sun StorageTek 2540 Array
provides a Fibre Channel connection from the data host to the controller. The Sun
StorageTek 2530 Array provides a Serial Attached SCSI (SAS) connection from the
data host to the controller.
The Sun StorageTek 2501 Array drive expansion tray provides additional storage.
You can attach the drive expansion tray to either the Sun StorageTek 2540 Array or
the Sun StorageTek 2530 Array.

Rear-Access Components of the Trays
Components that are accessed from the rear of the Sun StorageTek 2540 Array and
the Sun StorageTek 2530 Array controller trays include:
■ Controller Modules – Two removable controller modules.
■ Power-fan assembly – Two removable power supply modules with cooling fans.
The power-fan assembly is identical and interchangeable to the power-fan
assemblies used for Sun StorageTek 2501 Array drive expansion tray.
FIGURE 1-4 Controller Tray Rear-Access Components

1. Controller Modules

2. Power-Fan Assembly
Modules
Components that are accessed from the rear of the Sun StorageTek 2501 Array drive
expansion tray are:
■ I/O Modules (IOMs) – Two removable input/output modules
■ Power-fan assemblies – Two removable power supply modules with cooling
fans. The power-fan assembly is identical and interchangeable to the power-fan
assemblies used for Sun StorageTek 2540 Array and the Sun StorageTek 2540
Array.
The Sun StorageTek 2540 Array and the Sun StorageTek 2530 Array have two
controllers. The controllers manage the input/output (I/O) between the volumes
and the data host. The controllers have an Ethernet connection to the management
host for out-of-band management and contain a battery that provides backup power
to the 1 GB DIMM cache memory for up to three days in the event of a power loss.
Because each controller tray contains two controllers, the data path through one
controller can fail and the other controller provides a redundant data path to all of
the disk drives. If a controller fails, you can replace the failed controller while the
power is applied and the storage array is processing data (a hot swap). The system
automatically updates the firmware for the new controller so that it matches the
configuration database.
Each controller has a media access control (MAC) address that identifies it on the
network. The MAC address for a controller is on a label on the controller. The MAC
address label is attached to the controller in two places: at the top of the tray and at
the rear of the tray.
The tray ID numbers are set by the trays themselves on first power on. However,
you can change the setting through the Common Array Manager software. The tray
ID numbers on both of the controllers in one controller tray are identical under
optimal operating conditions.
Sun StorageTek 2540 Array
This Fibre Channel (FC) controller tray provides the following capabilities:
6Sun StorageTek 2500 Series Array Hardware Installation Guide • March 2007
■ Two data host connectors per controller that can support either a fiber-optic
interface or a copper interface with 1, 2, or 4 Gb/s data host connection speed
■ One drive expansion tray Serial Attached SCSI (SAS) connector with 3 Gb/s drive
expansion tray connection speed
■ 512-MB or 1-GB mirrored cache
■ Maximum connection of 36 disk drives (one controller tray and two drive
expansion trays)
When fiber-optic cables are used to connect to the data host, a Small Form-factor
Pluggable (SFP) transceiver is required to make the connection.

SFP Transceivers
You can connect the Sun StorageTek 2540 Array to either copper host interface cables
or fiber-optic host interface cables. If you use fiber-optic cables, you must install an
SFP transceiver in each interface connector on the controller where a fiber-optic cable
is to be installed. The SFP transceiver is required to translate the optical signals from
the fiber-optic cable into digital signals for the controller.
Note – The SFP transceiver shown might look different from those that are shipped
with your controller tray. The difference does not affect transceiver performance.

Controller Tray and Drive Expansion Tray PowerFan Assembly
The power-fan assembly for the Sun StorageTek 2540 Array, the Sun StorageTek 2530
Array, and the Sun StorageTek 2501 Array is identical and interchangeable.
Note – A minimum of two disk drives must be operating in a controller tray or a
drive expansion tray to avoid generating a power-fan assembly error.
The power-fan assembly contains an integrated cooling fan. The power supply
provides power to the internal components by converting incoming AC voltage to
DC voltage. The fan circulates air inside of the tray by pulling air in through the
vents on the front of the assembly and pushing the air out of the vents on the back
of each fan.
Each tray contains two power-fan assemblies. If one power supply is turned off or
malfunctions, the other power supply maintains electrical power to the tray.
Likewise, the fans provide redundant cooling. If one of the fans in either fan housing
fails, the remaining fan continues to provide sufficient cooling to operate the tray.
The remaining fan runs at a higher speed until the failed fan is replaced. Replace the
failed fan as soon as possible.
Chapter 1 Tray Overviews9
Sun StorageTek 2501 Array
The drive expansion tray expands the storage capacity of a storage array. The
controllers in the controller tray can connect to the drive expansion tray and access
the disk drives in the drive expansion tray for additional storage. A drive expansion
tray contains both physical components (disk drives, IOMs, and power-fan
assemblies) and logical components (virtual disks and volumes).
Drive Expansion Tray IOM
The drive expansion tray contains two IOMs that provide the interface between the
disk drives in the drive expansion tray and the controllers in the controller tray. The
IOM also monitors sub-system parameters. Each controller in the controller tray
connects to an IOM.
If one IOM fails, the other IOM provides a redundant data path to the disk drives.
You can replace a failed IOM while the power to the storage array is turned on and
the storage array is processing data (a hot swap).
Drive Expansion Tray IOM Connectors
The IOM connects to the controller tray and drive expansion trays with SAS cables.
Each IOM in a drive expansion tray has two SAS expansion connectors. One
connector shows an up arrow, and the other connector shows a down arrow.
FIGURE 1-9 SAS Connectors on the Drive Expansion Tray IOM
When connecting the SAS cable from an IOM in one drive expansion tray to an IOM
in another drive expansion tray, connect from a down arrow to an up arrow. If the
cable is plugged into two connectors with arrows of the same direction,
communication between the two drive expansion trays is lost.
