Safety Precautions

When installing the HP Rack Storage/12, always keep the following safety and

environmental issues in mind, especially if you install the NetServer in a non-HP

Rack environment:

Maximum Recommended Ambient Temperature. The maximum

recommended ambient temperature is 35°C (95°F).

Elevated Operating Ambient Temperature. The ambient operating

temperature with a closed or multi-unit rack assembly may exceed the room's

ambient temperature. Make sure that the temperature within the rack itself does

not exceed 35°C (95°F).

Reduced Air Flow. As you mount equipment in the rack, make sure that you

allow enough air flow for safe operation of the equipment.

Mechanical Loading. Uneven mechanical loading within the rack can cause

hazardous conditions. Plan the placement of equipment in the rack to make sure

that this problem does not occur.

Circuit Overloading. Make sure that the total configuration of equipment in the

rack does not overload the supply circuit. To this end, check the nameplate

ratings on all equipment. Consider the effect of circuit overloading on

overcurrent protection and supply wiring.

Reliable Grounding. Maintain reliable grounding of rack mounted equipment.

Give particular attention to supply connections that are not direct connections to

the branch circuit: the use of power strips, for example.

1 HP Rack Storage/12 Overview

The HP Rack Storage/12 provides mass storage for use in an HP NetServer rack

mounted configuration. The HP Rack Storage/12 is compatible with the SCSI

(Small Computer System Interface) industry standard.

The embedded SCSI adapters in HP NetServers, and accessory SCSI adapters,

connect the host system and the HP Rack Storage/12. Adapters are available from

Hewlett-Packard (check with your HP Reseller). The HP NetServer adapters

include software that supports a variety of operating systems.

One or two RS/12 SCSI Cards connect the HP Rack Storage/12 to the host

system.

The HP Rack Storage/12 System can be configured in one of three operating

environments: simplex, duplex, or cluster. The simplex configuration accesses up

to 12 addressed hard drives. The cluster configuration accesses up to 12

addressed hard drives from two host systems. The duplex configuration accesses

two banks of up to six hard drives each. The duplex configuration is useful for

either a small number of drives per channel or mirrored configurations. The hard

drives are available in a variety of capacities to meet your mass storage needs.

Front View

Figure 1-1 shows the front view of the HP Rack Storage/12 system with half

height hard drives, low profile hard drives, and drive spacers installed. The

visible components are the Status LEDs, the drive cage, and the bezel.

Status LEDs

The three Status LEDs indicate the current operating status of the HP Rack

Storage/12.

Bezel

The bezel covers the chassis, the support rails, and the thumbscrews securing the

chassis to the support rails. The bezel clips on to the chassis and can be installed

and removed without tools.

Drive Cage

The drive cage supports the installation of 8 half-height hard drives, 12

low-profile hard drives or a combination of half-height and low profile hard

drives. Drive spacers are used between half-height and low-profile hard drives.

Filler panels in unused drive slots are mandatory to maintain proper drive

cooling.

Configurations

Internal chassis braces divide the drive cage into four sections. Each section can

support the following hard drive configurations (see Figure 1-1):

•Three low-profile hard drives

•Two half-height hard drives

•One low-profile drive, one half-height drive and one drive spacer

SCSI Channels

Two internal SCSI channels connect the hard drives to the RS/12 SCSI card.

Hard drives installed in the left-half of the drive cage are connected to Channel 1.

The hard drives installed in the right-half of the drive cage are connected to

Channel 2 (see Figure 1-2).
