Compaq ProLiant DL380
Generation 2 Server
High-Density Deployment in
Compaq Racks
Abstract: This white paper is intended for use as a planning guide
to expedite concentrated deployments of several
Compaq ProLiant
 DL380 Generation 2 servers in a Compaq rack.
Use this white paper in conjunction with documents for the
ProLiant DL380 Generation 2 server and Compaq rack deployment
products. This paper is intended for Field Systems Engineers (FSEs)
and customers (IT managers, system managers, account managers,
and installers).
Executive Summary
Many business enterprises and service providers use network
infrastructure and web applications that work best on dedicated
servers. This creates the need to fit a large number of smaller servers
into existing server rooms and data centers. Compaq meets this need
with the density-optimized line of ProLiant servers such as the
ProLiant DL380 Generation 2 server. At a height of 2U each, up to
21 ProLiant DL380 Generation 2 servers can fit in a single Compaq
42U rack. While the ProLiant DL380 Generation 2 server has clear
space saving benefits, its compressed size presents new challenges
for rapid server deployment, as well as cable management and
environmental considerations.
Compaq engineers have developed innovations in rapid high-volume
deployment and improved cable management for large installations
of ProLiant DL380 Generation 2 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.
IMPORTANT: This document discusses only the ProLiant DL380
Generation 2 server, the Compaq 7000- and 9000-series racks, and
related Compaq rack options. This document does not discuss other
Compaq servers or products or racks not manufactured by Compaq.

Server Warnings
Adhere to the following guidelines when servicing or installing a Compaq 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 may 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 DL380 Generation 2 server at a time. A rack may become
unstable if more than one ProLiant DL380 Generation 2 server is fully extended for
any reason.
CAUTION: Do not overload the AC supply branch circuit that provides power to the
rack.

Introduction
Compaq designed the dense ProLiant DL380 Generation 2 server to meet the challenges
associated with deploying a high concentration of servers in a single rack. Compaq suggests that
customers evaluate their environments, power distribution, console, cable, and thermal
management choices well in advance to ensure the efficient deployment of multiple

Compaq Confidential - Need to Know Required
14UH-0701A-WWEN
ProLiant DL380 Generation 2 servers in a rack. Use this document, in conjunction with the
documents listed in Appendix A, as a guideline for planning rack configurations for high-volume
deployments of ProLiant DL380 Generation 2 servers.
The “Power Distribution Units” section outlines Compaq PDU choices best suited for building
rack configurations. This section provides technical specifications for high- and low-voltage
PDUs. It also describes how to allocate the correct number and type of PDUs for specific rack
deployments.
The “Planning Rack Configurations” section provides weight information for individual rack
components to help address floor support requirements. It also describes cable systems.
The “Console Management Systems” section provides information on server management
options.
All discussions of power requirements for ProLiant DL380 Generation 2 servers are based on the
input power of the server. This document uses the maximum rated power supply input of 575 W
for calculation purposes. However, derating the input power may be effective to:
• 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.
For more information about input power derating, see Appendix C.
IMPORTANT: In this document, derating the input power budget means using less than the
maximum rated input power values for the power supply. To derate the input power, see
Appendix C. Compaq strongly recommends that the derated power budget satisfies all the
installation requirements, including future upgrade plans.
Refer to the Compaq ProLiant DL380 Generation 2 Server QuickSpecs for detailed specifications
and options for the ProLiant DL380 Generation 2 server.

Glossary
1U – A rack unit (1U) is 4.45 cm or 1.75 inches in vertical dimension. The height of a device,
(also known as form factor), can be expressed in rack units (Us). The ProLiant DL380
Generation 2 server is a 2U server.
1U Integrated Keyboard/Mouse/TFT −
−−
−The TFT5600 RKM (rack-mount keyboard and
monitor) is a 1U integrated keyboard and monitor. Its full 15-inch TFT active matrix display
provides flicker-free, quality display at viewing angles up to 120 degrees horizontally and
105 degrees vertically.
Flat Panel Display (FPD) – A Compaq 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. Compaq recommends using a high-
voltage source to support high-volume deployments of ProLiant DL380 Generation 2 servers
in a rack.
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 Compaq rack depth and provides enough
space behind it to mount a Compaq Server Console Switch.
Keyboard/Video/Mouse (KVM) – KVM refers to a keyboard cable, a video cable, a mouse
cable, or a switch. Some Compaq parts lists may 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 paper, in-rack local console refers to a flat panel display

Compaq ProLiant DL380 Generation 2 Server High-Density Deployment in Compaq Racks 9

14UH-0701A-WWEN
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 DL380 Generation 2 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. See the
“Power Distribution Units” section of this paper.
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. Compaq recommends
using the remote-console system for managing a large number of servers because it
eliminates the congestion of KVM cabling.
Remote Insight Lights-Out Edition – The Compaq Remote Insight Lights-Out Edition is
designed to provide remote access and control of Compaq ProLiant server products from
anywhere on the network with a standard web browser. Consequently, customers can deploy
a ProLiant DL380 Generation 2 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. Using the Remote Insight Lights-Out Edition, customers can deploy 21
ProLiant DL380 Generation 2 servers in a 42U Compaq rack with significantly fewer cables
than in a local console.
Server Console Switch – A device that enables multiple servers in a rack to be accessed and
managed by a single keyboard, mouse, and monitor. These switches are also known as KVM
switches.
Sliding Rail – A toolless rack management system designed for Compaq 7000- and 9000-series
racks that supports in-rack serviceability for ProLiant DL380 Generation 2 servers.
UID LED and Switch – The blue Unit Identification LED identifies the ProLiant DL380
Generation 2 server requiring service. A UID switch toggles both the front and rear UID
LEDs simultaneously.
Wake on LAN (WOL) – An option that enables a remote restart of the server.

Note 1: These numbers are determined using a single power source (non-redundant).
Note 2: This PDU supports power from two different sources. If one power source fails, the PDU uses the alternate source.
Note 3: This PDU must be hard-wired to the power source by a certified electrician.
Note 4: This PDU requires Compaq Vertical Mount Bracket kit (PN# 191265-B21 or 166097-B21 with high-voltage Y-cables) to vertically mount
in rack side panel.
Note 5: This PDU is no longer being shipped by Compaq.
In Compaq 7000- and 9000-series racks, the 295363-xxx PDU series must be installed vertically
in the rack side panels to prevent interference with the server rack rails. Compaq Vertical-Mount
PDU Bracket kits enable PDUs to be mounted vertically in the side compartments of 7000- and
9000-series racks. Compaq offers two Vertical-Mount PDU Bracket kits:
• Compaq Vertical-Mount PDU Bracket (P/N 191265-B21): This kit includes eight brackets
that support four PDUs. This kit works best with low-voltage applications that use the power
cord included with the server.
• Compaq Vertical-Mount PDU Bracket with High-Voltage Cables (P/N 166097-B21): This kit
includes 11 Y-cables and 4 brackets that support 2 PDUs. This kit works best with high-
voltage, high-current PDUs. Using the Y-cables enables each power outlet on the PDU to
supply power for 2 servers.

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 DL380 Generation 2 server is either 3.2 A at 200 to 240 volts or 6.4 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.
IMPORTANT: The examples shown in the following sections use the maximum rating of the
power supply. They are for reference only.
Non-Redundant Power
The following examples illustrate how to calculate the number of servers per PDU when using
non-redundant power.
Example
One high-voltage PDU (P/N 207590-D72) has a current rating of 24 A. The server has a total
input current rating of 3.2 A at 200 volts.
24 A (PDU current rating) / 3.2 A (server total input current rating) = 7
This PDU can support a maximum of 7 servers at full server input current ratings.
Example
One low-voltage PDU (P/N 207590-D71) has a current rating of 24 A. The server has a total
input current rating of 6 A at 100 volts.
24 A (PDU current rating) / 6.4 A (server total input current rating) = 3
This PDU can support a maximum of 3 servers at full server input current ratings.
Redundant Power
The ProLiant DL380 Generation 2 server supports a redundant power supply. The power supply
for this server automatically senses input voltage level.
When using redundant power, it is necessary to use two PDUs per server. The following
examples illustrate how to calculate the number of servers per pair of PDUs when using
redundant power.
Example
Two high-voltage PDUs (P/N 207590-D72) have a combined current rating of 48 A. The
server has a total input current rating of 3 A at 200 volts (redundant power).
2 [24 A (PDU current rating) / 3.2 A (server total input current rating)] = 7
These PDUs can support a maximum of 7 servers at full server input current ratings.
Example
Two low-voltage PDUs (P/N 207590-D71) have a current rating of 48 A. The server has a
total input current rating of 6 A at 100 volts (redundant power).

2 [24 A (PDU current rating) / 6.4 A (server total input current rating)] = 3
These PDUs can support a maximum of 3 servers at full server input current ratings.

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
1.8288 m (6 ft) in length. This length provides enough slack for the power cord to route through
the cable management arm.
High-Voltage Y-Cables
The Vertical-Mount PDU Bracket with 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 7 for part numbers.
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 DL380 Generation 2 servers in the
standard configuration or one ProLiant DL380 Generation 2 server in the maximum
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 a full rack
of 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:
• Rack Rail kit (standard rack rails and cable management arm, Telco rack solution, or
third-party rack cabinet and cable management arm )
• KVM server to console cables [1.8 m (6 ft) cables for sliding rail solutions]
• One or two RJ-45 cables for NIC 1 and NIC 2
Table 11 outlines the number of devices that fully populate a 42U or 36U rack with an in-rack
local console.

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:
• Rack Rail kit (standard rack rails and cable management arm, Telco rack solution, or third-
party rack cabinet and cable management solution)
• KVM server to console cables
• One or two RJ-45 cables for NIC 1 and NIC 2
Remote Console Management
The Compaq Remote Insight Lights-Out Edition board is a PCI-based board that enables server
management by remote access regardless of the state of the host server operating system or the
host CPU. The Remote Insight board sends alerts and performs other functions even if the host
server operating system is not responding. For installation information and features, refer to the

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 keyboards, 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
All of these factors influence floor support requirements, future service and upgrade
requirements, 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 DL380 Generation 2 servers. See the following example:
1 ×9142 rack 114 kg (253 lb)
21 ×ProLiant DL380 Generation 2 server
with hard disk drives
567 kg (1,260 lb)
21 ×Cable management system 76 kg (168 lb)
3 ×High-voltage PDUs with brackets 17 kg (38 lb)
22 ×High-voltage Y-cables 9 kg (21 lb)
21 ×Keyboard/Video/Mouse cables 27 kg (59 lb)
Total configured rack weight 810 kg (1,800 lb)
IMPORTANT: Compaq recommends populating a rack with ProLiant DL380 Generation 2
servers and other rack option products only after the rack is in or very near its final position.
Compaq does not recommend transporting a fully populated rack.

Special Considerations for 7000-Series Racks
Compaq recommends deploying servers in either a 7000- or 9000-series Compaq rack. 4000-
series racks (36U) are not recommended for 2U high-volume deployments with ProLiant
DL380 Generation 2 servers because they are not sturdy enough to support the weight of 18
servers. The 7000- and the 9000-series Compaq racks mentioned in this section are the 7142,
9142, and 9136, racks. This document does not discuss deploying servers in any rack not
manufactured by Compaq.
