Deploying ProLiant DL320 and

DL360 Servers into

Telecommunication (Telco)

Racks

Abstract: Compaq ProLiant DL320 and ProLiant DL360 servers

were developed with high volume deployment in mind. As a result,

Compaq addresses environmental, thermal, mechanical, power,

installation and service considerations for the server and rack

specific options.

While Compaq 9000 and 7000 series racks are ideal for this

ultra-dense server, Compaq recognizes that customers may want to

plan and implement deployments using telecommunications (telco)

racks. This document describes deployments involving the Compaq

ProLiant DL360 server and the Compaq Telco Rack Option Kit.

Compaq provides hardware, specifications, and guidelines for

ultra-dense deployment schemes using telco racks as a service to its

customers.

13NS-1000A-WWEN

Introduction

Compaq designed the ProLiantDL320 and ProLiant DL360 ultra-dense servers with

maximally configured deployments in mind. The Compaq ProLiant DL320 and ProLiant DL360

servers require only 1U (1.75 inches) of rack height.

This document discusses installation and service issues that arise when working with ultra-dense

server deployment, including:

•Mounting options for varying rack environments

•Weight

•Power distribution

•Thermal and environmental considerations

•Console management choices

•Cable management

•Unit identification

This paper provides guidelines for deploying multiple Compaq ProLiant DL360 servers in a telco

rack environment using the Compaq Telco Rack Option Kit (P/N: 174576-B21), and provides

information on Compaq rack products and related options. For information regarding third-party

racks, see the white paper, “Compaq Ultra-Dense Server Deployment in Third-Party Racks,”

Rack Warnings

This document should be used only as an information source for planning your deployment.

Avoid personal injury and equipment damage by following accepted safety practices.

WARNING: Ensure proper floor support. Deployment of ultra-dense servers, related equipment,

and cables exceeds 1,800 pounds for a Compaq ProLiant DL360 single 42U rack and 1,700

pounds for a ProLiant DL320 single 42U rack.

WARNING: Be aware of the center of gravity and tip hazard. Compaq recommends that the

rack footings extend 10 inches from the front and back of any Compaq rack 22U or higher.

Adequate stabilization measures are required. Ensure that the entire rack assembly is properly

secured and that all personnel are trained in proper maintenance and operation procedures. Tip

hazards include personal injury and death.

CAUTION: Ensure your installation has adequate power supply and branch circuit protection.

CAUTION: Thermal dissipation requirements of an ultra-dense server deployment mandate

minimum unrestricted airspace of 3 inches in both the front and the rear of each Compaq

ProLiant DL320 and ProLiant DL360 server.

Telco Rack Option Kit

Compaq ProLiant DL320

The Compaq Telco Rack Option Kit for Compaq ProLiant DL320 servers provides a complete

mounting solution that adapts to a variety of telco racks. The telco rack rails adjust to

accommodate telco rack frame thickness from 3 to 5 inches (7.62 to 12.7 cm).

Compaq ProLiant DL360

The Compaq Telco Rack Option Kit for Compaq ProLiant DL360 servers provides a complete

mounting solution that adapts to a variety of telco racks. The telco rack rails adjust to

accommodate telco rack frame thickness from 3 to 5 inches (7.62 to 12.7 cm).

Kit Contents

The installation kit includes a set of adjustable rack rails that attach to telco racks using fasteners

included in the kit. The rack rails mate to optional server rails that replace the standard rails

preinstalled on the Compaq ProLiant DL320 and ProLiant DL360 server.

The Compaq Telco Rack Option Kit comes with a detailed installation guide. Consult the

installation guide for details on adapting the option kit to your telco rack.

Note: The Compaq Telco Rack Option Kit is for fixed rail installation. Although the Compaq

ProLiant DL320 and ProLiant DL360 servers slide in for installation, remove the servers from the

rack for service.

Cantilever Design

The Compaq Telco Rack Option Kit rack rails support the server, distributing the load in the front

1and to the rear 2. This balanced cantilever design balances the installation much better than a

full cantilever design. The balanced cantilever installation is robust, without blocking access to

other front panel mount equipment in the rack.

Figure 4: Cantilever specifications for Telco Rack Option Kit (Compaq ProLiant DL360 shown)

WARNING: The center of gravity of fully configured Compaq ProLiant DL320 and ProLiant

DL360 servers installed using the Compaq Telco Rack Option Kit is slightly behind the telco

rails. The telco rack must be fully secured to adequate support structures for deployments of ultra-

dense 1U Compaq ProLiant DL360 servers.

Table 2 lists the weights of individual components used in deployments of Compaq ProLiant

DL320 and ProLiant DL360 servers in telco racks.

Table 2. Component Weights for Calculation

Item Weight (ProLiant DL320) Weight (ProLiant DL360)

Configured (1 server) 25.00 lb 29.00 lb

Fully configured (42 servers) 1,030 lb (approx) 1,200 lb (approx)

Wide Ultra3 hard disk drive 1.90 lb 1.90 lb

Remote Insight Lights-Out Edition option 0.50 lb 0.50 lb

Telco Rack Option Kit rack rails (set) 2.50 lb 2.50 lb

KVM cable bundle 1.42 lb 1.42 lb

High voltage Y power cable 1.00 lb 1.00 lb

Server console switch 5.25 lb 5.25 lb

WARNING: External cable weight contributes to the overall weight of the rack installation.

Because cable installation and load-bearing designs vary greatly, carefully consider cable weight

in all designs.

WARNING: Do not exceed the specified weight limit for the telco rack or the floor. When

creating deployments of Compaq ProLiant DL320 or ProLiant DL360 ultra-dense servers in a

telco rack, include in the weight calculations the weight of the rack rails, cable management trays,

and cables whose load is bearing on the rack.

CAUTION: Ensure that the cabling design provides both adequate airspace for thermal

dissipation and strain relief for the cable connections on the Compaq ProLiant DL360 or ProLiant

DL320 server if the cable management tray is not used. The cable management tray design

reduces cable congestion and relieves strain on connectors.

13NS-1000A-WWEN

If the Compaq ProLiant DL360 and ProLiant DL360 servers do not include Wide Ultra3 hard

disk drives 1, or a Remote Insight Lights-Out Edition option 2, subtract those component

weights from the weight total.

Figure 5: Hard drive and Remote Insight locations (DL360 shown)

Floor Loading

All buildings and raised computer room floors are engineered to provide a specific floor loading.

The floor area beneath the rack must be designed to provide proper support for a fully populated

rack. When configuring a system, ensure that the floor loading specifications are adhered to.

Failure to do so may result in physical injury or damage to the equipment and the facility.

Dimensions

Compaq designed the Compaq Telco Rack Option Kit to comply with EIA 310-D specifications

for rack width.

Table 3 lists the minimum dimensions for installing Compaq ProLiant DL320 and

ProLiant DL360 servers using the Compaq Telco Rack Option Kit. When designing deployments

of ultra-dense servers in telco racks, include the minimum airspace requirements for the server.

IMPORTANT: Any installation of Compaq ProLiant DL360 servers will require 3 inches

airspace front and back.

Table 3. Minimum space requirements for ProLiant DL320 and ProLiant DL360 servers installed

using Compaq Telco Rack Option Kit

ProLiant DL320 ProLiant DL360

1Height 1.75 in (1U) 1.75 in (1U)

2Width 17.72 in 17.72 in

3Unrestricted airspace measured forward from front

of telco rack18.65 in (5.65 in cantilever space, plus 3 in of airspace for

thermal dissipation)

4Unrestricted airspace measured rearward from front

of telco rack 222 in (19 in cantilever space, plus 3 in of airspace for

thermal dissipation)

Note 1: The minimum space requirements above do not include the spatial requirements for sliding the ProLiant DL360

server onto the rack rails. This installation procedure requires at least 27 inches, measured forward from the front of the

telco rack.

Note 2: The minimum space requirements above do not include the recommended spatial requirements for cable

installation and service procedures. Compaq recommends at least 8 inches for cable attachment and service

procedures, measured from the back of the installed server.

IMPORTANT: Compaq products are designed to provide airflow from the front of the rack to

the rear. It is recommended that rack components only be installed on the front rails for many

reasons, including proper airflow.
