General description
The DS2500 is a dual-redundant Fibre Channel (FC) loop storage system used on systems running
HP-UX operating system software. The DS2500 occupies 3 EIA units in a standard 19-inch rack. Up to
14 disk drivescanbemountedinthefrontoftheenclosure. Upto4DS2500scanbedaisy-chained
together to create a storage ring.
Features
The DS2500 disk enclosure provides:
•Redundant power supplies and blowers
Only one operational power supply and one operational blower are required for the DS2500
to function.
•FC disk drives that can be added or replaced with the system on (although the affected file
systems must be taken offline)
•Environmental services sensors that monitor the disk enclosure and provide real-time error reporting
•High-availability to minimize unplanned downtime
•Customer-replaceable components
Each DS2500 is connected to Host Bus Adapters (HBAs) through two independent Fibre Channel
Arbitrated Loop (FC-AL) buses, also known as loops, to provide no single point of failure (NSPOF). Each
disk drive connects to loop A through I/O module A, and to loop B through I/O module B. Figure 1
shows the maximum configuration of four DS2500s.
The disk enclosure supports high-availability requirements through the following features:
•Hot-pluggable components
•High-capacity, high-speed disks
•Redundant, customer replaceable power supplies and blowers
•Redundant I/O modules
•Support for mirrored disks in the HP-UX environment
•Online firmware upgrades
•Hardware event monitoring and real-time error reporting

Components
Figure 2 shows the components of the DS2500 from front and rear views.
DS2500 front view
The front of the DS2500 holds the following components:
•Up to 14 FC disk drives mount in bays numbered 1 through 14 sequentially, from left to right. For
simplicity, a drive is referred to by its bay number.
•Enclosure status indicators located in the lower corner to the right of bay 14.
DS2500 rear view
The rear of the DS2500 holds the following components:
•An Environmental Monitoring Unit (EMU) that provides protection against catastrophic failures. It
monitors, records and reports disk enclosure status conditions to the operating system software.
•Redundant power supply and blower assemblies that provide protection against power overloads,
short circuits, and overheating
•Redundant I/O modules that provide an interface between the disks and the HBA

Status indicators
You can monitor DS2500 performance by observing various status indicators:
•Indicators on the front of each disk drive report individual disk drive status.
•Indicators on the front lower corner of the enclosure report overall DS2500 status.
•Indicators on the top rear of the EMU report overall DS2500 status (duplicates of the indicators
on the front of the enclosure).
•Astatu
s LED on each power supply/blower assembly verifies proper operation of the assembly.
•Status LEDs on each I/O module indicate the detection of transceiver signals and power.
•An audible alarm alerts you to an error condition.
Specific LED information is provided in the description of the individual components in Chapter 2.
System requirements
Operating system software
The DS2500 is supported on the following HP-UX systems:
•For PA-RISC: HP-UX 11.11 and 11.23
•For IPF: HP-UX 11.23

•I/O modules, page 18
•Power supplies and blowers, page 20
•FCdisks, page 21
• Cables and cabling,page24
•Transceivers, page 24
List of parts
The DS2500 consists of:
•ADualloopc
hassis
•14 disk bays
•Up to 14 FC disk drives
•Drive blanks
•An EMU
•2I/Omodules
•2powersu
pplies
•2blowers
•Small Form-factor Pluggable (SFP) transceivers
•Fiber optic cables
EMU
The EMU monitors and records disk enclosure status information.
EMU functions
The primary functions of the EMU include:
•Display or change the enclosure ID (En)
•Display or change the enclosure loop ID
•Monitorenclosureoperation
•Detect, report, record, and display enclosure error status conditions
•Implement automatic corrective actions for some conditions
•Provide a means for you to view error condition reports
HP StorageWorks 2500 Disk System user guide 17

Whenever the EMU detects a condition that could affect operation, it performs the following operations:
•Generates an audible alarm
•Displays status in visual indicators
•Generates an error condition report
•Reports the condition to the HP-UX application software
Controls and displays
Figure 3 identifies the EMU displays, controls, and connectors.
25236a
Figure 3 EMU controls and displays
1. Status indicators:
a. EMU heartbeat—Flashing green signifies an operational EMU
b. DS2500 power—Solid green signifies that the +5 VDC and +12 VDC signals are within
an acceptable range
c. DS2500 fault—Solid amber indicates that an enclosure error condition exists (normally off)
2. Alphanumeric display—A two-character display of the enclosure functions and status (typically
displays the enclosure ID).
3. Function select push button and back light—Enables you to specify what information appears in
the alphanumeric display. Pressing and releasing, or tapping the function select button allows
you to sequence through the different sublevels of a display group. The back light is on when
an error condition exists.
4. Display group select push button and back light—Enables you to view display groups and
control the audible alarm. The back light is on when the audible alarm is muted or disabled.
5. Communication ports—Unused in a JBOD environment
I/O modules (E-PBC)
TwoI/Omodulesprovideaninterfacebetweenthedisksandthehostsystem.TheI/Omodulesareused
to route data to and from the disks in a dual-loop configuration to eliminate a single point of failure.
Each disk drive is connected to both I/O module A and I/O module B (Figure 4-3). Each I/O module is
connected to an independent, external FC loop. I/O module A connects to loop A, and I/O module B
connects to loop B (see Figure 1 on page 14).
18 Compon ents

CAUTION:
Keep the loops completely separate to ensure that the failure of a single component (I/O module,
transceiver, or cable) does not stop data transmissions to active drives.

3. FC disks (3 are shown, but up to 14 disks are supported in each DS2500)
Figure 4 Redundant disk connections
The operation and function of both I/O modules are identical. Each I/O module has two ports that
can transmit and receive data for bidirectional operation. Port use and connections are configuration
dependent (see "Cables and cabling" on page 24). Each port is identified with a transceiver element
number,anditsstatusisdisplayedonanLED(Figure 5). Port 1 is the bottom loop port, and port 2 is
the top loop port.
•Port 2 LED—On indicates that a signal was detected at the top transceiver.
•Power LED—On indicates that power is present on the I/O module.
•Port 1 LED—On indicates that a signal was detected at the bottom transceiver.
