Abstract: This white paper is a planning guide to expedite



concentrated deployments of several ProLiant
Generation 2 (G2) servers in a single rack. Use this white paper in
conjunction with documents for the ProLiant DL360 G2 server and
Compaq rack deployment products as necessary. This paper is
written for Field Systems Engineers (FSEs) and customers (IT
managers, system managers, account managers, and installers).

Executive Summary

Many business enterprises and service providers implement a
distributed architecture for their infrastructure, remote client access,
and web applications. In these cases, individual applications are
loaded on multiple machines creating the need to tightly fit a large
number of density optimized servers into existing server rooms and
data centers. Compaq meets this need with the density-optimized line
of ProLiant servers, such as the ProLiant DL360 G2 server. At a
height of 1U each, up to 42 ProLiant DL360 G2 servers can fit in a
single Compaq 42U rack. This server has clear space saving benefits;
its compressed size presents new challenges for rapid server
deployment, cable management and environmental considerations.

DL360

Compaq engineers have developed innovations in rapid high-volume
deployment and improved cable management for large installations
of ProLiant DL360 G2 servers. This white paper introduces
planning, power and thermal considerations, server and rack
requirements and installation configurations. It also outlines the
products associated with high-volume deployment in Compaq rack
configurations, such as keyboard, video, and mouse infrastructure.

IMPORTANT: This document discusses the ProLiant DL360 G2
server primarily and the Compaq 7000-, 9000- and 10000-series
racks and related Compaq rack options secondarily. This document
does not discuss other Compaq servers, products or racks not
manufactured by Compaq, although the ideas presented here may be
applied to third party racks.

Server Warnings

Adhere to the following guidelines when servicing or installing a ProLiant DL360 G2 server:

WARNING: To reduce the risk of electrical shock or damage to the equipment:

• Unplug the power cord from the system.

• Do not disable the power cord grounding plug. The grounding plug is an important

safety feature.

• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible

at all times.

CAUTION: To properly ventilate the system, provide at least 7.6 cm (3 inches) of
clearance at the front and back of the computer.

CAUTION: The system is designed to be electrically grounded. To ensure proper
operation, plug the AC power cord only into a properly grounded (earthed) AC outlet.

Rack Warnings

WARNING: To reduce the risk of personal injury or damage to the equipment:

• Do not attempt to move or relocate an equipment rack populated with servers. A

fully populated rack can weigh as much as 771 kg (1,700 lb). The rack might become
unstable and cause serious personal injury or equipment damage.

• Before installing the servers, extend the leveling jacks to the floor and rest the full

weight of the rack on the leveling jacks. Either install the stabilizer kit or couple
multiple racks together for stability.

• Always load the heaviest item first and load the rack from the bottom to the top.

Loading in this manner makes the rack “bottom-heavy” and helps prevent the rack
from becoming unstable.

• Extend only one ProLiant DL360 G2 server at a time. A rack might become unstable

if more than one server is fully extended for any reason.

CAUTION: Do not overload the AC supply branch circuit that provides power to the

rack.

ProLiant DL360 G2 Server High-Density Deployment 6

Introduction

The dense ProLiant DL360 G2 server was designed to meet the challenges associated with
deploying a high concentration of servers in a single rack. Customers should evaluate their
environments, power distribution, console, cable, and thermal management choices well in
advance to ensure efficient deployments.

All discussions of power requirements for ProLiant DL360 G2 servers are based on the input
power of the server. This document uses the maximum rated power supply input of 308 W for
calculation purposes. However, de-rating the input power might be effective to help:

• Minimize the number of PDUs required for each rack.

• Match the rack current requirements with the existing circuit breaker capacity.

• Match the rack cooling requirements with the existing facility cooling capability.

IMPORTANT: In this document, de-rating the input power budget means using less than the
maximum rated input power values for the power supply. Make sure the de-rated power
budget satisfies all the installation requirements, including future upgrade plans.

Refer to the Compaq ProLiant DL360 G2 Server QuickSpecs for detailed specifications and
options for the ProLiant DL360 G2 server.

1713-0702A-WWEN

ProLiant DL360 G2 Server High-Density Deployment 8

Flat Panel Display (FPD) – A TFT5010R (15-inch) flat panel monitor provides a large image

size and exceptional screen performance in a space-saving 2U size that enables the monitor to
be neatly tucked away when not in use.

High-voltage – AC line voltage of 200 V to 240 V. With higher voltage levels, a server can use a

lower current and still meet its power requirements. It is recommended to use a high-voltage
source to support high-volume deployments of ProLiant servers in a rack.

Integrated Lights-Out – The Integrated Lights-Out (iLO) is an intelligent microprocessor for

remote administration and is embedded on the system board of some new density optimized
ProLiant servers. To access the functionality, an IT administrator would connect a standard
network cable to the dedicated Integrated Lights-Out management port. This port can be
connected to a corporate intranet, the Internet (via VPN technology), or a separate
management network. No additional software is needed to run this advanced management.
An administrator accesses the console via a standard browser from anywhere, any time.

In-Rack Keyboard – The 1U Rack Keyboard Drawer and the Internal Keyboard with Trackball

are designed to work together to save room in space-constrained, rack-mount environments.
The 1U Keyboard Drawer requires only half the rack depth and provides enough space
behind it to mount a Server Console Switch.

Keyboard/Video/Mouse (KVM) – KVM refers to a keyboard cable, a video cable, a mouse

cable, or a switch. Some parts lists might refer to KVM switches as Server Console Switches.

Local Console –A local console system interacts with a server using a set of KVM devices and

can be in-rack or off-rack. In this document, in-rack local console refers to a flat panel
display and a keyboard/trackball in the same rack as the servers. Off-rack local console
refers to any combination of a display, a keyboard, and a pointing device located outside of
the rack. A local console system does not use a network connection to interact with the
server.

Low-Voltage – AC line voltage of 100 V to 120 V.

N.A. – North America, including U.S., Canada, and Mexico.

Network Interface Controllers (NICs) – Controllers that are embedded on the system board of

the ProLiant DL360 G2 server.

Power Distribution Unit (PDU) – A PDU is a high-voltage or low-voltage device that is

equipped with circuit breakers that help prevent electrical surges and external equipment
malfunction by providing over current and surge protection for connected devices. Refer to
the “Power Distribution Units” section of this document for more information.

Remote Console – A remote console is a server console system that uses a network connection to

interact with the server. This system enables any computer with appropriate software and
network access to control a server from anywhere across the globe. Use the remote-console
system when managing a large number of servers because it eliminates the congestion of
KVM cabling.

Remote Insight Lights-Out Edition – The Remote Insight Lights-Out Edition is designed to

provide remote access and control of ProLiant server products from anywhere on the network
with a standard web browser. Consequently, customers can deploy a server in a true
“headless” fashion with a minimum of only three cables per server: one power cord for the
server, one network cable for the LAN connection, and one network cable for the Remote
Insight Lights-Out Edition management LAN connection.

1713-0702A-WWEN

managed by a single keyboard, mouse, and monitor. These switches are also known as KVM
switches.

Sliding Rail – A tool-free racking system designed for Compaq and third-party racks that support

in-rack serviceability for ProLiant servers. Customers with this option could slide the server
entirely out of the rack to remove the top access panel without removing any of the cabling
from the rear of the server.

UID LED and Switch – The blue Unit Identification (UID) LED recognizes when the ProLiant

server requires service. A UID switch toggles both the front and rear UID LEDs
simultaneously.

Wake on LAN (WOL) – An option that enables a remote (re)start of the server.

Understanding Power, Thermal, Weight and
Console Management Considerations

Power, thermal, and weight are the most important considerations for optimizing a hardware
installation in high-volume server environments. The type of console management system used in
a server environment is determined by the rack deployment.

Table 4 provides server parameters necessary to calculate the power, thermal, and weight
requirements for any number of ProLiant DL360 G2 servers. Console management considerations
are discussed in detail later in this section.

Power and Thermal Budgeting

Note: In this document, de-rating the input power budget means not using the maximum rated
input power values for the power supply. It is strongly recommended the installation planner

ensures the de-rated power budget satisfies all the installation requirements, including
future upgrade plans.

All ProLiant DL360 G2 power requirement discussions in this document are based on the input
power of the server, since this number has direct impact in planning for the PDU selection and the
facility power source. Use one of the following methods during the facility power distribution
planning to account for the ProLiant DL360 G2 input power.

1. Use the maximum rated input power of 308 W.

2. Use the Power Calculator Utility (provided in Active Answers) to configure your system as it
will be used; providing all the relevant power and cooling parameters needed to plan an
installation. For more information on the Power Calculator Utility, refer to our website
located at:

www.activeanswers.compaq.com/aaconfigurator/PowerCalc/DL360G2.xls

3. Use the de-rated input power, which can be calculated by adding the power budgets of
installed optional components from the rated input power.

4. Use the allocated input power, which can be calculated by dividing the maximum power of a
PDU by the number of servers. This calculated power should be at least 250 W to support all
the optional components initially released with the ProLiant DL360 G2.

1713-0702A-WWEN

ProLiant DL360 G2 Server High-Density Deployment 11

The power budgets of optional components referred to (in the following sections) were derived
from the system input power of a set of selectively measured server configurations. The
configurations measured range from a basic low-end configuration to a fully populated high-end
configuration. Since the input power values for a ProLiant DL360 G2 server in an installation
might vary depending on the software applications, the information provided in this section
should be used as a guideline only.

The ProLiant DL360 G2 server power supply is designed to support future upgrades of
processors, DIMMs, and hard disk drives. As such, the power supply output power is rated at
200 W. Considering the power supply efficiency of 65% (including the Power Factor Correction);
the power supply input power is rated at 308 W. This input power value may be used in planning
for the power source implementation and facility cooling requirements. In some cases the input
power requirement for each ProLiant DL360 G2 server might be desired to be lower than 308 W.
For example,

• To minimize the number of PDUs, that is, the number of facility power feed lines, required

for each rack.

• To match the rack current requirements with the existing facility branch circuit breakers.

• To match the rack power and cooling requirements with the existing facility power and

cooling limitations.

Table 5 demonstrates how significant reduction in input current and thermal dissipation can be
realized, if a deployment plan can limit each ProLiant DL360 G2 configuration over the useful
lifetime of a rack configuration.

Table 5. De-rated Current and Thermal Dissipation for Reduced Input Power Assumptions

De-Rated Fully Rated

Input Power 120 W 250 W 308 W

Input Current @110 V AC 1.09 A 2.27 A 2.80 A

Input Current @208 V AC 0.57 A 1.20 A 1.48 A

Thermal Dissipation 409 BTUs/hour 852 BTUs/hour 1050 BTUs/hour

The de-rated input power values of 120 W and 250 W can be correlated with the measured input
power values for the minimum and maximum configurations for ProLiant DL360 G2 servers.
However, the de-rated input power value must be high enough to account for any future upgrades
for a deployment plan.

As stated earlier, the power supply is designed to support future processor and hard drive
upgrades. When installing 42 servers, the number of PDUs to be installed will depend on the
support for the input current requirement. Carefully de-rating the input power may very well
satisfy deployment needs and also reduce the number of PDUs per rack. Reducing the number of
PDUs has a direct impact on the deployment time and maintenance of an installation.

Input Current and Thermal Dissipation Calculations

The input power is the key in deriving the input current and thermal dissipation. For a given input
power, the input current will vary depending on the input voltage level.

1713-0702A-WWEN

ProLiant DL360 G2 Server High-Density Deployment 12

The relationship among the current, the voltage and the power for the power supply input is as
follows:

Input Current = Input Power / Input Voltage

For example,

Input Current = 100 W /110 V = 0.91 A
Input Current = 100 W /208 V = 0.48 A

The input power of a server depends on the operational state of the system. For example, during
the initial power up, a server consumes more power due to the hard disk drives spin-ups. It should
be noted that in the ProLiant DL360 G2, the two hard disk drives spin-up one after the other.
Therefore, the peak input power requirement changes significantly when the first drive is added,
but not as much when the second drive is added. After the initial power up, the input power varies
depending on the operating system and the application software running on the server. During
standby, only the auxiliary portion of the power supply is consuming power to support operations
of a very limited part of the system, for example, the Remote Insight Lights-Out Edition option,
NICs, and so on.

The thermal dissipation can be calculated from the input power as follows:

Thermal Dissipation = Input Power * 3.41

For example,

Thermal Dissipation = 100 W * 3.41 = 341 BTUs/hour
Thermal Dissipation = 292 W * 3.41 = 996 BTUs/hour

The easiest way to calculate the thermal dissipation for the entire rack is to add the input power
requirements for all the servers and other units populated in a rack, and then multiply the total
input power by 3.41.

Measured Input Power

Table 6 lists the measured input power of ProLiant DL360 G2 with varying subsystem
components, to illustrate the effects of adding or removing optional components. Table 7 lists
each subsystem component's input power derived from Table 6. A few test programs were run to
exercise various parts of the system. Also, the current and power were measured on the input side
of the power supply. The “peak” and “typical” input power values were measured during power
up and idle/normal operations, respectively.

Input Power Budget De-rating

If a deployment plan limits the future expansion beyond certain configurations options, which
may be added in the future, then adjustments can be made to the expected input current and
thermal requirements of the servers.

• To de-rate the input power, start with the minimum configuration (Configuration 1 from

Table 6). Add the typical power of the components included in the desired system
configuration to calculate the de-rated power budget. Typical input powers for various
components are listed in Table 7.

Example

Assuming the desired server configuration is as follows; use Table 8 to calculate the de-rated
power budget using the typical power from Tables 6 and 7.

Processors: 2 x 1.40 GHz

Memory: 4 x 128 MB

Storage: 2 x 18.2 GB

Smart Array Controller 5302: 1 x SA5302

6. Calculate the thermal dissipation.
Thermal dissipation for the desired configuration (in BTUs)

196 W

196 W × 3.41

668 BTUs/hour

Therefore, the new power budget for this configuration is 196 W (compared to the rated 308 W),
and the thermal dissipation is approximately 668 BTUs/hour (compared to the rated 1050
BTUs/hour).

The rated input power for the ProLiant DL360 G2 power supply is 308 W. Therefore, the power
budget for a maximum configuration is 308 W and the thermal dissipation will be approximately
(308*3.41=) 1050 BTUs/hour.

This de-rated input power budget significantly reduces the power and thermal requirements for
highly populated racks. This also reduces the number of PDUs for certain configurations, which
lowers cost and decreases deployment time. Costs for the facility electrical plumbing, data center
floor ventilation, and facility air conditioning installation can be reduced.

IMPORTANT: It is strongly recommended to verify that the de-rated power budget satisfies all
the installation requirements, including future upgrade plans.

Input Power Budget Allocation

This section explains how to allocate the input power budget for each server. This method can be
used when a PDU is to support a known number of ProLiant DL360 G2 servers. It is important to
verify that the calculated power budget allocation will be sufficient to support the worst-case
server configurations that are to be deployed.

The allocated input power for each server is calculated by multiplying the allocated input current
for each server with the line voltage.

Allocated Input Power = Allocated Input Current * Input Line Voltage

Example

Assume a high voltage PDU rated at 24 A is to support 21 servers. Each server can be allocated

1.143 A. If the line voltage is assumed to be at 208 V, then the allocated input power budget for
each server will be (1.143*208) = 238 W.

Since the input power budget of 238 W exceeds the fully configured system measured input
power of 195 W (as shown in Table 6), 21 ProLiant DL360 G2 servers can be supported by a
24 A high-voltage PDU. That means, only two of these PDUs are needed to support 42 servers
in a 42U rack.

Power Distribution Units

Designed for use in high-volume rack deployments, Compaq offers several PDU models ranging

The Modular PDUs (with up to 32 outlets) provide easy accessibility, increased outlet count, and
flexibility; therefore, allowing you to mount the units in different locations within the rack. All
mounting hardware, including both the 0U and 1U mounting brackets are included in the Modular
PDU kit (no additional mounting brackets need to be purchased).

Legacy Single Input 0U/1U PDUs range from 16A - 40A and offer up to 12 outlets. The 0U
mounting brackets are included in the PDU kit (1U mounting brackets need to be purchased
separately, 215852-B21).

The Dual Input PDU, equipped with two input ends and a built-in AC transfer switch, is a
fault-tolerant solution that automatically switches over to a secondary input source when the first
(primary) source becomes unavailable. The Dual Input PDUs ship with both 0U and 1U mounting
brackets (no additional mounting brackets need to be purchased). Table 9 lists PDU options. For

Figuring Type and Number of PDUs

The type and number of PDUs required to power a full rack of servers depends on each server’s
power requirement, the number of servers deployed in the rack, and the available power for the
servers.

Compaq PDUs support both high-voltage and low-voltage applications. The input current rating
for a ProLiant DL360 G2 server is either 1.48 A at 200 to 240 volts or 2.80 A at 100 to 120 volts.
To determine the number of servers supported by a PDU, divide the PDU’s current rating by the
server’s total input current rating.

9.1 kg
20 lb

9.1 kg
20 lb

IMPORTANT: The examples shown in the following sections use the maximum rating of the
power supply. They are for reference only.

Example

One high-voltage PDU (P/N 252663-D72) has a current rating of 24 A. The server has a total
input current rating of 1.48 A at 208 volts.

24 A (PDU current rating) / 1.48 A (server total input current rating) = 16

This PDU can support a maximum of 16 servers at full server input current ratings.

Example

One low-voltage PDU (P/N 252663-D71) has a current rating of 24 A. The server has a total
input current rating of 2.80 A at 110 volts.

24 A (PDU current rating) / 2.80 A (server total input current rating) = 8

This PDU can support a maximum of 8 servers at full server input current ratings.

For more information on PDUs, refer to the website located at:

www.compaq.com/ups

Selecting Server Power Cords

The appropriate server power cord to use depends on the cable management system installed in
the rack. Generally, the sliding rail cable management system requires a power cord that is 1.8 m
(6 ft) in length. This length provides enough slack for the power cord to route through the cable
management arm.

1713-0702A-WWEN

ProLiant DL360 G2 Server High-Density Deployment 17

Power Cords

The ProLiant DL360 G2 server ships with an IEC-IEC power cord (PN 142257-002) used for
rack mounting with high voltage Power Distribution Units (PDUs). For low voltage, stand-alone
deployments or installation without a rack, country-specific power cord options are available.

U.S. & Japan models will ship with two power cords - IEC-IEC and country-specific cord:

• Power cord, US, IEC320-C13 to IEC320-C14, 10 A 250 V, Straight (10 ft / 2.5 meter)

(PN 142257-002)

• Power cord, US, IEC320-C13 to NEMA 5–15P, 15 A 125 V, Straight (10 ft / 3 meter)

(PN 103541-001)

High-Voltage Y-Cables

The Vertical-Mount PDU Bracket with a High-Voltage Cables kit includes 11 Y-cables, each of
which is 3.0 m (10 ft) long. The single-cord PDU section is 1.8 m (6 ft) long, and the dual-cord
server section is 1.3 m (4 ft) long. See Table 9 for part numbers.

Note: You do not need the Vertical-Mount PDU Bracket to mount any of the PDUs listed in
Table 9; however, the Y-cables shipped with this kit may be used with the PDUs.

Y-cables have a single-cord section with an IEC connector that connects to the PDU, a dividing
joint in the center, and a dual-cord section with IEC connectors that connect to the servers. One
Y-cable supplies power from the PDU to two ProLiant DL360 G2 servers in the standard
configuration.

CAUTION: When installing server power cords into the PDUs, ensure that the load is
balanced among the output circuit breakers. Do not exceed the ratings of the circuit
breakers.

Console Management Systems

A console management system enables a single keyboard and video console to control multiple
servers. Install an in-rack console management system in the same rack with the servers it
manages. Install an off-rack console management system in the local vicinity of the rack of
servers it manages. Use a remote console management system to manage a rack of servers from
any other system connected to the same network.

In-Rack Local Consoles

With an in-rack local console, all equipment, servers, switchboxes, keyboards, keyboard drawers,
and video displays are installed together in the same rack. One console switchbox can support up
to eight pieces of equipment.

Each server deployed in a fully populated rack with an in-rack local console management system
requires the following accessories for successful deployment and operation:

• KVM server to console cables [1.8 m (6 ft) cables for sliding rail solutions].

• Universal Rack Rail (the quick deploy rail kit that ships standard with the server and comes

with a cable management solution), or the option Sliding Rail Kit (with cable management
solution), or optional telco rack solution.

Off-Rack Local Consoles

When an off-rack local console is used, certain components such as console switchboxes,
keyboards, and video displays do not populate space in the rack, but are located in close
proximity to the rack. Because of this, the rack can be fully populated with servers. Cable lengths
for connecting servers to an off-rack local console vary in length depending on the location of the
console.

Each server deployed in a fully populated rack with an off-rack console management system
requires the following accessories for successful deployment and operation:

• KVM server to console cables.

• Given the thickness of the KVM cables, it is recommended to keep the console management

system within the rack, especially in highly concentrated server deployments.

Remote Console Management

The new Integrated Lights-Out (iLO), the next generation of Compaq’s Lights-Out technology,
simplifies the life-cycle ownership of ProLiant servers. In the future, customers will receive the
robust Lights-Out capabilities built into more ProLiant servers.

ILO includes an intelligent microprocessor and can be accessed via a new, dedicated Lights-Out
port on the rear bezel of the server. This port can be connected to a corporate intranet, the Internet
(via VPN technology), or a separate management network. Accessed via a standard browser from

1713-0702A-WWEN

ProLiant DL360 G2 Server High-Density Deployment 19

anywhere, the Integrated Lights-Out capabilities will not require any unique software applications
to use. ILO provides essential server management and diagnostics features combined with basic
Lights-Out capabilities standard on the server. The essential features of iLO are referred to as iLO
Standard. ILO Standard features include:

• Simplified setup

• Text-based console (for access to server boot sequences)

• Text-mode operating system console

• Remote power on/off

• Detailed server status, logs, virtual indicators, and diagnostics

• Automatic server recovery

The sophisticated virtual administration features of iLO can be easily accessed with a license key
available with the Integrated Lights-Out Advanced option kit. The iLO Advanced feature suite
include Virtual Graphical Console and Virtual Floppy Drive that provide significant cost savings
by removing the time it takes to be physically present in front of the server for routine access and
maintenance. The graphical remote console is accessible from anywhere on the network via a
standard Microsoft Internet Explorer browser and is available during all server states (setup, boot,
OS, and halted). The break-through Virtual Floppy enables remote deployment, remote
application installation, and remote upgrade of servers thereby allowing customers to save time
and money in their deployment, management, upgrade, and troubleshooting efforts. The
Integrated Lights-Out functionality will extend to include Virtual CD that will be available as a
free upgrade to iLO Advanced customers.

Each server deployed in a fully populated rack with a remote console management system
requires the following accessories for successful deployment and operation:

• Integrated Lights-Out Advanced Pack

• An RJ-45 cable for the Integrated Lights-Out management port

Planning Rack Configurations

Consider several important factors when planning a rack configuration:

• The number of servers deployed in the rack

• The number of other devices such as keyboard drawers, video displays, and console

switchboxes that support the servers

• The number of PDUs and their orientation

• The type of rack

• The rack management system

• The console management system

• The remote management system

• Network interface scheme

All of these factors influence floor support requirements, future service, as well as upgrade and
installation requirements.

Table 12 lists the weight and power specifications for Compaq racks and rack option products. To
calculate floor support requirements for a particular rack configuration, add the weight
measurements to calculate the total weight of a rack fully populated with ProLiant DL360 G2
servers.

IMPORTANT: Populate a rack with ProLiant DL360 G2 servers and other rack option products
only after the rack is in or very near its final position. Do not transport a fully populated rack.

Special Considerations for Compaq Racks

Use the following considerations as guidelines for the ProLiant DL360 G2 server.

1713-0702A-WWEN

ProLiant DL360 G2 Server High-Density Deployment 21

b

WARNING: Follow these guidelines to reduce the risk of personal injury or damage to
the equipment:

• Do not install a ProLiant DL360 G2 server into a rack until the rack has been placed in

its final location.

• Pre-install slide rails, PDUs, power cords, and cables into the rack in a build room or

other location before moving the rack to its final location.

• Extend the leveling jacks to the floor and rest the full weight of the rack on the jacks

efore installing any servers. The casters are not designed to support the full weight of

a populated rack.

• Do not move a rack populated with servers. A fully populated rack can weigh up to

1,800 pounds. Moving a populated rack can cause the rack to become unstable,
resulting in serious personal injury or equipment damage.

To effectively cool the ProLiant DL360 G2 server in a 7000-series rack, replace the front door of
the rack with the High Air Flow Rack-Door. Insert before deploying the servers in the rack.

Use the Rack Extension kit (P/N 154392-B21) to alleviate any space problems for cable bundles
at the rear of 7000-series racks.

Rack Management Systems

To determine the best rack management solution, consider the service and upgrade demands of
the servers deployed in the rack.

Universal Rack Rails

Because not all customers use Compaq racks, the ProLiant DL360 G2 server design supports
deployment in many environments, Compaq ships standard a Universal Rack Rail that works in
both Compaq and third-party rack cabinets. This kit includes variable length rack rails that are
compatible with a variety of third-party racks depths and will work with either round or square
holes. The Universal Rack Rail can be installed in racks that are 610 mm (24 inches) to 787 mm
(31 inches) deep.

Sliding Rack Rails

The Sliding Rack Rails and cable management solution are conducive to in-rack servicing and
provide convenient access to the server cables and connectors. With this solution, a server can be
powered down and serviced without disconnecting the server cables or removing the server from
the rack.

The Sliding Rack Rails and cable management solution use the same adjustable depth rack rail
mechanism for either square or round hole racks. Therefore, they are designed for Compaq or
third-party racks. The sliding rack rails compress and snap securely in place in the rack without
screws or nuts.

A steel-cable pulley operates as the cable management solution and attaches directly onto the rear
of the rack rail. It secures and routes the power, network, KVM cords, and cables along the rear
of the rack. When a server is extended from the front of the rack for servicing, the steel cable
from the cable pulley extends as well. This not only prevents the cables from sagging and
tangling, but it also enables proper air ventilation through the rack while enabling the servers to
be fully extended without disconnecting any of the server cables.

1713-0702A-WWEN

ProLiant DL360 G2 Server High-Density Deployment 22

Refer to the Compaq ProLiant DL360 G2 Setup and Installation Guide for complete installation
instructions.

Telco Rack Solution

Many data centers use two post telecommunication (telco) racks. The ProLiant DL360 G2 server
design supports deployment in telco racks. Compaq offers a telco rack kit designed to install
ProLiant DL360 G2 servers in telco racks. This kit includes rack rails and screws that are
compatible with a variety of telco racks. The telco rack kit includes replacement server rails
designed to fit on the ProLiant DL360 G2 server. Before deploying ProLiant DL360 G2 servers
into a telco rack, remove the standard server rails and replace them with the telco server rails
included in the telco rack kit.

IMPORTANT: Always install the Compaq telco rack kit when deploying a ProLiant DL360 G2
server in a telco rack.

ProLiant DL360 G2 Server High-Density Deployment 23

Configuration A: Maximum Performance Density
(42 Servers, High-Voltage)

This configuration shows a “best practice” for a 42U rack with 42 servers in a high-voltage
facility where a deployment plan can accommodate the de-rating of each ProLiant DL360 G2
server. The “Power and Thermal Budgeting” section explains power budgeting methods and
measured power for different base-line configurations and subsystem components. The following
calculation verifies supporting 42 servers with 2x40 A high voltage PDUs:

Since there are 2 PDUs supporting 42 servers, each PDU needs to support 21 servers. A 40 A
high-voltage PDU supporting 21 servers can allocate each server with maximum current of
(40/21=) 1.905 A @ 208 V
will be:

. Therefore, the allocated maximum input power for each server

1.905 A * 208 V = 396 W

Since the maximum input power per server is 308 W, 308 W will be used to calculate the
maximum thermal dissipation per server. It will be:

308 W * 3.41 = 1050 BTUs/hour

For 42 servers, the total thermal dissipation will be (1050*42=) 44,112 BTUs/hour

.

In the “Measured Input Power” section of this document, a fully configured system was measured
to consume lower than 250 W (Table 6, Server Configuration 4). If each de-rated server
configuration input power is lower than 238 W, then 42 servers can be supported via this
configuration summary.

Configuration B: Maximum Flexibility (35 Servers,
High-Voltage)

The following calculation verifies supporting 35 servers (de-rated Power Budget) with 24 A high­voltage PDUs:

Since there are 2 PDUs supporting 35 servers, 4 KVM switches, 4 Ethernet switches, and (1) 1U
Keyboard/Monitor, each PDU needs to support up to 22 devices. A 24 A high-voltage PDU
supporting 19 servers can allocate each server with maximum current of (24/19=) 1.26 A.
Assuming 208 V, the allocated maximum input power for each server will be:

1.26 A * 208 V = 263 W

The maximum thermal dissipation per server will be:

263 W * 3.41 = 897 BTUs/hour

For 35 servers, the total thermal dissipation will be (897*35=) 31,395 BTUs/hour

.

In the “Measured Input Power” section of this document, a fully configured system was measured
to consume lower than 250 W (Table 6, Server Configuration 4). If each de-rated server
configuration input power is lower than 263 W, then 35 servers can be supported via this
configuration summary.

Configuration C: Traditionalist (28 Servers, Low-Voltage)

The following calculation verifies supporting 28 servers (de-rated Power Budget) with 24 A
low-voltage PDUs:

Since there are 4 PDUs supporting 28 servers, 4 KVM switches, 2 Ethernet switches, 2 Ethernet
hubs and (1) 1U Keyboard/Monitor, each PDU needs to support up to 18 devices. A 24 A
low-voltage PDU supporting 8 servers can allocate each server with maximum current of (24/8=)

3.0 A. Assuming 110 V, the allocated maximum input power for each server will be:

3.0 A * 110 V = 330 W

The maximum thermal dissipation per server will be:

330 W * 3.41 = 1,125 BTUs/hour

For 28 servers, the total thermal dissipation will be (1,125*28=) 31,508 BTUs/hour

.

In the “Measured Input Power” section of this document, a fully configured system was measured
to consume lower than 250 W (Table 6, Server Configuration 4). If each de-rated server
configuration input power is lower than 330 W, then 28 servers can be supported via this
configuration summary.

Installation Procedures

Note: Take necessary precautions for all procedures.

This section describes the preparation and brief installation procedures that are common to
various configurations described in the previous section.

1. Server Preparation

2. Rack Preparation

3. Installing PDUs

4. Installing the Rack Rails

5. Installing a Server in a Rack

6. Connecting Cables

7. Completing the Installation

Execute Steps 2 through 7 in order, especially when multiple racks are connected together or
when a rack is populated in a separate room and relocated to its final position. Step 1 can be done
any time before Step 5.

Server Preparation

This section briefly describes the preparation necessary for the ProLiant DL360 G2 server. Refer
to the Compaq ProLiant DL360 G2 Setup and Installation Guide and accompanying
documentation for details.

The ProLiant DL360 G2 server comes standard with Universal Rack Rails as a fast deployment
solution for fixed rack rail kits. If the application does not require in-rack servicing, then the
factory-equipped fixed-rails may be used for installation.

The sliding rails and the cable management solution option allows the server to be extended fully
from the rack, temporarily locked in place for servicing, and without removing the cables from
the server. It also provides better access to the rear cabling connections. If customers choose to
use the sliding rail and cable management solution option, then replace the factory-mounted fixed
server rails with the optional sliding server rails on the server. Then install the optional cable tray
to the rear of the server chassis per the instructions that come with the option.

Prior to installing a ProLiant DL360 G2 server in a rack, install all the necessary optional
components inside the server, such as the PCI option cards, additional processor, and additional
DIMMs.

Rack Preparation

Most of the discussions in this section will focus around Compaq 42U racks. The rack selection
criteria and recommendations are beyond the scope of this document. A bustle or an extension kit
might be required if the installation will end up with several cables for all ProLiant DL360 G2
servers, for example, KVM cables. For complete details on rack installation, refer to the set up
and install guides for the respective rack models.

1713-0702A-WWEN

ProLiant DL360 G2 Server High-Density Deployment 35

Installing Power Distribution Units

PDU installation varies depending on the rack configuration, the number of servers deployed in
the rack, the selected type of PDU, as well as the voltage and current rating for each PDU. For
information on Modular or Dual Input PDUs, refer to the information located on the website at:

www.compaq.com/ups

Routing Power Cords

Use the following general procedures to route server power cords in 36U, 42U, and 47U racks.

IMPORTANT: When installing server power cords into the PDUs, ensure that the load is
balanced among the output circuit breakers.

Power Cords

To route and connect power cords:

IMPORTANT: Route and connect the power cord to the PDU after the server is installed.

1. Connect the power cord to the server first and route it through the cable management system
with the other server cables.

2. Route the power cord inside the rear rack support to the PDU.

IMPORTANT: In 7000-series racks, route the power cables from the servers to the PDUs
through the gap in the rear of the rack rail.

High-Voltage Y-Cables

To route high-voltage Y-cables:

1. Connect the single-cord section of the Y-cable to the PDU installed on the same side as the
cable management tray.

2. Align the Y-joint with the rear rack support and center it between the rack rails of the two
servers that the Y-cable supports.

3. Use two plastic tie wraps to secure the Y-joint to the rack support.

4. After installing the servers, connect the cables to the servers and route them through the cable
management system with the other server cables.

Installing the Rack Rails

The following procedure describes how to install the standard rack rails onto the rack. The rails
are designed to snap in place without screws or nuts.

1. Remove the server rails from the left and right standard rails.

2. Insert the rails into the rack holes.

3. Insert the server into the rack.

4. Install the cable management arm.

5. Cable and power up the server.

1713-0702A-WWEN

ProLiant DL360 G2 Server High-Density Deployment 36

Repeat the procedure for any subsequent rack rails. For detailed instructions on installing
standard rack rails, refer to the Compaq ProLiant DL360 G2 Server Setup and Installation Guide
and to the Compaq ProLiant DL360 G2 Hardware Configuration and Installation Poster.

CAUTION: Always install servers from the bottom of the rack to the top. Installing
servers in this manner provides more stability for the rack and reduces the risk of the rack
tipping over.

IMPORTANT: Before installing the rack rails for the standard rack rails and cable
management arm, remove the server rails from the slide rail assembly. See the “Server
Preparation” section in this document for more information.

IMPORTANT: Install a ProLiant DL360 G2 server in every U-space from the bottom to the
top for maximum density.

Installing a Server in a Rack

Install ProLiant DL360 G2 servers in the rack from the bottom to the top. Tighten the
thumbscrews on the front of each server to secure the server to the rack. Attach the cable
management arm to the rear of the server and to the rear of the rack.

WARNING: To reduce the risk of serious personal injury, fire, or damage to the
equipment:

• Extend the leveling jacks to the floor and rest the full weight of the rack on the

leveling jacks.

• Install either the stabilizer kit or couple multiple racks together for stability.

• Load the heaviest item first and load the rack from the bottom to the top. Loading the

rack in this manner makes the rack “bottom-heavy” and helps prevent the rack from
becoming unstable.

• Do not overload the AC supply branch circuit that provides power to the rack.

• Extend only one ProLiant DL360 G2 server at a time. A rack might become unstable

if more than one server is fully extended for any reason.

Connecting Cables

This section discusses connecting and routing cables with different cable management solutions
and different console management solutions.

1. Connect the cables to each device installed in the rack, working from the bottom to the top.

2. Connect the cables to the bottom piece of equipment.

3. Bundle the cables and route them through the cable management solution.

4. Connect the cables to the console switchbox.

5. Connect the power cord to the PDU. Do not connect the PDU to any power source until all
equipment is fully deployed in the rack.

1713-0702A-WWEN

ProLiant DL360 G2 Server High-Density Deployment 37

Refer to Compaq ProLiant DL360 G2 Server Setup and Installation Guide for the recommended
order for connecting cables.

When the cables are properly connected and routed through the cable management arm, the rear
door of the rack closes easily over the cables. If the rear door does not close easily, additional
space might be required. Install the rack extension or the bustle kit to provide more space for the
cables at the rear of the rack.

WARNING: To reduce the risk of electrical shock or damage to the equipment:

• Unplug the power cord from the system.

• Do not disable the power-cord-grounding plug. The grounding plug is an important

safety feature.

• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible

at all times.

• Do not route the power cord where it can be walked on or pinched by items placed

against it. Pay particular attention to the plug, electrical outlet, and the point where the
cord extends from the server.

IMPORTANT: In 7000-series racks, route the power cables from the servers to the PDUs
through the gap in the rear of the rack rail.

Integrated Lights-Out for Remote Console Management

The remote console management system uses a CAT5 cable connected to the RJ-45 connector in
the Integrated Lights-Out management port. Route this cable according to the instructions in the
Compaq ProLiant DL360 G2 Server Setup and Installation Guide. Connect the CAT5 cable to
the network data line outlet.

Completing the Installation

To complete the installation:

1. Install side panels on the outsides of the end racks.

2. Install the front and rear doors.

3. Connect the PDUs to the power source.

4. Power up the servers.
