Overview

HP StorageWorks Disk System 2120

The HP StorageWorks Disk System 2120 is a 1-EIA unit disk systems capable of accommodating up to four disk modules. It is designed to provide inexpensive, high performance rack-optimized online mass storage for entry-level configurations in three distinct markets: (1) HP servers/workstations, (2) open systems JBODs, and (3) open systems IDACs (Internal Disk Array Controller).

The DS2120 supports U320 drives; however, the U320 drives are supported at a maximum of 160 MB/s speeds.

Connectivity to U320 initiators is supported if the speed of the U320 initiator is set to limit negotiations to U160 speed. The U320 drives do not operate reliably or at acceptable performance levels at U320 speeds and are not supported at those speeds. This is due to limitations within the disk system and not the U320 drive mechanisms.

Components of the Disk System

Front Panel

The disk modules can be accessed from the front of the disk system. It can accept up to 4 low profile disk drives. If your storage system contains less than 4 disk modules, the remaining empty slots contain filler panels. These filler panels (part number A6198-60002) ensure that the proper cooling is maintained within the storage system. Remove filler panels only when a disk module is added to the system.

Disk Module LEDs

Each disk module has two LEDs: an amber LED on the top (see Figure 1) and a green LED on the bottom. The amber LED is not operational. The green LED provides disk module status information as listed in Table 6.

SCSI ID Switch

The SCSI ID switch sets the address for the disk drives.

There are three possible settings for the SCSI address switch: A, B, and C. Each setting assigns a different set of addresses to the disk modules installed in the disk system. For SCSI address switch setting A, the addresses for the installed disk modules are (from left to right, looking at the disk system from the front) 0, 2, 4, and

6. For SCSI address switch setting B, the addresses for the installed disk modules are 8, 10, 12, and 14. For SCSI address switch setting C, the addresses for the installed disk modules are 9, 11, 13, and 15. See Figure 5, below.

SCSI address 7 is reserved for use by the host bus adapter.

Electrical Requirements

AC Site Requirements

Overcurrent protection devices are required for each cabinet where the disk system is installed. They must be positioned between the power source and the disk system. These protective devices must not trip when exposed to an inrush current of 30 amps lasting 5 ms.

English

Note These protection devices must meet all applicable electrical safety

requirements and be approved for the intended purpose.

Installing the Disk System

Hardware Requirements

The following hardware is included with the disk system:

One power cord comes with each disk system.

Your host computer must have one of the following:

■ An on board LVD SCSI port

■ An LVD SCSI host bus adapter board installed in the host system such as A7173A,

A6828A, A6829A, A5865A, A7059A, or A7060A.

You can view a complete and current list of supported host bust adapters at

http://www.hp.com/products1/serverconnectivity/support_matrices.html.

The following accessory is available for your storage disk system:

■ C2364A High Density 68-pin Terminator for LVD or Single-Ended

The DS2120 supports a maximum SCSI speed of U160. Connectivity to U320 initiators is supported if the speed of the U320 initiator is set to limit negotiations to U160 speed. U320 drives do not operate reliably or at acceptable performance levels at U320 speeds and are not supported at those speeds. This is due to limitations within the disk system and not the U320 disk mechanisms. Contact your HP support representative for assistance with the configuration.

Preparing for Installation

Before the disk system is ready for installation, its SCSI IDs must be set and the host system must be prepared to recognize the newly installed disk system. See your operating system administration manual for configuration procedures for the host bus adapter.
