Product Description
General Description
Hewlett-Packard’s StorageWorks Disk System 2405 (referred to in this guide as
the disk system) is a high-availability Fibre Channel (FC) storage product. Dual
optical fiber ports on dual link controllers provide Fibre Channel connections to
the host. Fifteen slots accept high-speed, high-capacity FC disks connected to a
FC midplane. Data throughput is 200 Mbytes/sec. Thirteen disk systems fill a
2-meter System/E rack. Filled with 18-Gbyte disks, the 2-meter Rack System/E
yields 3.51 Terabytes of storage; with 36-Gbyte disks, 7.02 Terabytes of storage;
and with 73-Gbyte disk, 14.23 Terabytes.
Modular and redundant components are easy to upgrade and maintain. Disks,
power supplies, and link control cards (LCCs) are replaceable parts that plug into
individual slots in the front and back of the disk system. Redundant power
supply/fan modules and LCCs can be removed and replaced without interrupting
storage operations. Disks can be replaced with the system on, and only the
affected file systems taken off-line. Hewlett-Packard technical support is optional
for these procedures.
Special electronics and HP-UX software enable remote monitoring and
diagnostics. Sensors on the LCCs monitor the disk system environment,
including temperature, voltage, fan speed, and component status. Hewlett-
Packard’s Command View SDM reports any changes in environmental status to
user-defined locations. Standard HP-UX diagnostic utilities also report
environmental data for enhanced troubleshooting.

Product Description
Status Indicators
LEDs on the disk system enable you to detect and replace failed components and
thereby prevent or minimize users’ downtime. For additional information about
LEDs, see chapter 4, Troubleshooting.
On the front of the disk system, a pair of LEDs indicates the status of the disk
system, and an LED for each slot shows disk I/O activity:
■The system power LED (B in Figure 1) indicates that power is on or off.
■The system fault LED (C in Figure 1) indicates whether or not a fault has
occurred anywhere in the disk system.
■At the bottom of each disk module, the left LED (D in Figure 1) indicates the
presence of I/O activity on the disk.
■The right LED, at the bottom of each disk module (E in Figure 1), can be
flashed to help a customer engineer (CE) locate the disk for physical
inspection or removal.
LEDs (G and J in Figure 2) on the back of the disk system indicate the status of
replaceable components. See chapter 4, Troubleshooting, for specific LED
information.
Power/Standby Switch
Located in the upper right corner of the front of the disk system, the power switch
(A in Figure 1) interrupts power from the power supplies to the LCCs and other
internal components. Power to the power supplies is controlled by the power
cords and the AC source.
High Availability
High availability is a general term describing computer systems that are designed
to minimize unplanned downtime. The disk system supports high availability
requirements through the following features:
■Hot-pluggable, high-capacity, high-speed disks
■Redundant, hot-pluggable, user-replaceable power supplies and LCCs
■Support for mirrored disks in the HP-UX environment
■Online firmware upgrades
■Hardware event monitoring and real-time error reporting

16 Product Description
Upgradability
You can increase disk system storage capacity by:
■Replacing disk drives with higher-capacity disk drives
■Adding disks in unused slots
■Adding another disk system to a FC loop
None of these actions require shutting down the product, but some may require
the use of system utilities to manage file systems.
Disk and LCC firmware is downloadable using the supported tools.
Environmental Services
Environmental services circuitry monitors the following elements:
■Fan rotation
■Power supply output
■Power supply and fan status
■Disk drive status, including fault conditions
■LCC status
■Temperature
■Self-test results
Each LCC reports the status of all elements in the disk system, even if the LCC
does not have direct access to the element.
Additionally, the EEPROM on each LCC stores 2 Kbytes of configuration
information and user-defined data, including the manufacturer serial number and
product number.

Product Description 17
Product Description
Components
User-replaceable components enable high availability and easy maintenance.
This section describes the following components:
■Disks and disk fillers
■LCCs
■Power supply/fan modules
Disks and Disk Fillers
Disks, shown in Figure 3, are 3.5-inch Low Profile disks in open metal carriers.
Disks are Fibre Channel.
The open carrier design requires careful handling to avoid disk damage by
breakage and static electricity. Avoid personal contact with hot surfaces.
WARNING Touching exposed circuits can cause electrical discharge and
disable the disk. Disks require careful handling and ESD
precautions.
The plastic parts of the disk are safe to touch:
■Extraction handle (A in Figure 3)
■Latch tab (B in Figure 3)
The initial disk options for this product are 73-Gbyte, 36-GByte and 18-GByte
drives. A label on the disk carrier shows the storage capacity and rotational speed
of the installed disk. Obtain information about the latest disk options from HP
sales representatives.
Disk fillers occupy unused slots to balance the air flow.
Caution Fillers must be installed in unused slots in order to maintain even
cooling around the remaining slots.

Product Description
Figure 4. LCC
Other features of the LCC are:
■LEDs (D) indicating LCC status and bus configuration
■Rotary switch (E)
■Configuration switch with four settings:
1 Link Speed (1.0625 Gb/s or 2.125 Gb/s)
2 Reserved
3 Reserved
4 Power fail warning (enable/disable)
■Locking screws (F)
■Cam levers (G)

20 Product Description
LCC circuitry provides the following functions:
■System fault detection
■Disk address generation
Caution If an LCC fails, do not remove it from the disk system until you
are ready to replace it with a new one. The failed LCC should
remain installed to assure proper cooling for the disk system.
