abstract
This white paper is a planning guide to expedite concentrated deployments of several HP
ProLiant DL360 Generation 3 servers in a single rack. Use this white paper in conjunction with
documents for the ProLiant DL360 Generation 3 server and Compaq branded 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 fit a large number of density-optimized
servers into existing server rooms and data centers. HP meets this need with the
density-optimized line of HP ProLiant servers, such as the ProLiant DL360 Generation 3 server.
At a height of 1U each, up to 42 of these servers can fit in a single Compaq branded 42U rack.
This server has clear space saving benefits; its compressed size presents new challenges for rapid
server deployment, cable management, and environmental considerations.
HP engineers have developed innovations in rapid high-volume deployment and improved cable
management for large installations of these 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 branded rack
configurations, such as keyboard, video, and mouse infrastructure.
IMPORTANT: This document discusses the ProLiant DL360 Generation 3 server primarily
and the Compaq branded 7000-, 9000- and 10000-series racks and related rack options
secondarily. This document does not discuss other servers, products or racks not manufactured by
HP, although the ideas presented here may be applied to third party racks.
general guidelines
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.
The dense ProLiant DL360 Generation 3 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 Generation 3 servers are based on the
input power of the server. This document uses the maximum rated power supply input of 396 W
for calculation purposes. However, derating 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.

hp ProLiant DL360 generation 3 server high-density deployment technical white paper 3
IMPORTANT: In this document, derating the input power budget means using less than the
maximum rated input power values for the power supply. Be sure the derated power budget
satisfies all the installation requirements, including future upgrade plans.
Refer to the HP ProLiant DL360 Generation 3 Server QuickSpecs for detailed specifications and
options for the ProLiant DL360 Generation 3 server.
Note: In this document, derating the input power budget means not using the maximum rated
input power values for the power supply. It is strongly recommended that the installation
planner ensures the derated power budget satisfies all the installation requirements,
including future upgrade plans.
power & thermal budgeting
accounting for server input power
All ProLiant DL360 Generation 3 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 server input power.
1. Use the maximum rated input power of the power supply: 445 W.
2. Use the Power Calculator Utility (provided in ActiveAnswers) 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
activeanswers.compaq.com/aaconfigurator/PowerCalc/DL360Generation 3.xls
3. Use the derated 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 365 W to support all
the optional components initially released with the server.
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 Generation 3 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 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 325 W. Considering the power
supply efficiency of 73 percent (including the Power Factor Correction), the power supply input
power is rated at 445 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 server might be desired to be lower than 445 W. For example:
• To minimize the number of PDUs, that is, the number of facility power feed lines, required
for each rack

hp ProLiant DL360 generation 3 server high-density deployment technical white paper 4
• 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 1 demonstrates how significant reductions in input current and thermal dissipation can be
realized, if a deployment plan can limit each server configuration over the useful lifetime of a
rack configuration.
Table 1. Derated Current and Thermal Dissipation for Reduced Input Power Assumptions
Derated Fully Rated
Input Power 220 W 370 W 445 W
Input Current @110 VAC 2.00 A 3.36 A 4.05 A
Input Current @208 VAC 1.05 A 1.77 A 2.14 A
Thermal Dissipation 750 BTUs/hour 1261 BTUs/hour 1517 BTUs/hour
The derated input power values of 220 W and 370 W can be correlated with the measured input
power values for the minimum and maximum configurations for ProLiant DL360 Generation 3
servers. However, the derated 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 derating 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.

for dimension, weight, power, and thermal requirements.
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.
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 drive spin-ups. It should
be noted that in the ProLiant DL360 Generation 3 server, the two 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, such as, the Remote Insight Lights-Out
Edition (RILOE) option, NICs, and so on.

hp ProLiant DL360 generation 3 server high-density deployment technical white paper 6
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 3 lists the measured input power of the server with varying subsystem components, to
illustrate the effects of adding or removing optional components. Table 4 lists each subsystem
component's input power derived from Table 5. A few test programs were run to exercise various
parts of the system. In addition, 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 Derating
If a deployment plan limits the future expansion beyond certain configuration 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 derate the input power, start with the minimum configuration (Configuration 1 from Table 3).
Add the typical power of the components included in the desired system configuration to
calculate the derated power budget. Typical input powers for various components are listed in
Table 5.
Example
Assuming the desired server configuration is as follows; use Table 5 to calculate the derated
power budget using the typical power from Tables 4 and 5.
Processors: 2 x 2.80 GHz
Memory: 4 x 512 MB
Storage: 2 x 18.2 GB
Smart Array Controller 5302: 1 x SA5302

4. Add the typical power for the PCI card. 9 W
5. Calculate the total power.
Typical power for the desired configuration (in watts)
292 W
6. Calculate the thermal dissipation.
Thermal dissipation for the desired configuration (in BTUs)
292 W ×3.41
996 BTUs/hour
Therefore, the new power budget for this configuration is 292 W (compared to the rated 445 W),
and the thermal dissipation is approximately 996 BTUs/hour (compared to the rated 1517
BTUs/hour).
The rated input power for the server’s power supply is 445 W. Therefore, the power budget for a
maximum configuration is 445 W and the thermal dissipation will be approximately
445*3.41 = 1517 BTUs/hour.
This derated 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 derated 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 used to support a known number of 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 14 servers. Each server can be allocated
1.71 A. If the line voltage is assumed to be at 208 V, then the allocated input power budget for
each server will be (1.71*208) = 356 W.
Since the input power budget of 356 W exceeds the fully configured system measured input
power of 292 W (as shown in Table 2), 14 ProLiant DL360 Generation 3 servers can be
supported by a 24 A high-voltage PDU. That means three of these PDUs are needed to support 42
servers in a 42U rack.

hp ProLiant DL360 generation 3 server high-density deployment technical white paper 9
power distribution units
HP offers a wide range of 1U/0U PDUs, supporting both low voltage and high voltage
applications. Designed especially for high volume rack deployments, HP PDUs help optimize
cable management and power distribution within the rack. These PDUs are equipped with circuit
breakers to provide short circuit and over current protection.
The Modular PDUs (mPDUs), range from 16 A to 40 A, and provide up to 32 outlets*, easy
accessibility, and improved cable management. These mPDUs have a unique modular
architecture that allows for increased flexibility and customization. And 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 for mounting mPDUs in the HP 9000/10000
racks).
In addition, HP also offers the Dual Input PDU, a fault-tolerant solution that automatically
switches over to a secondary input source when the first source fails. Equipped with two input
ends and a built-in AC transfer switch, this device is designed for mission critical environments
where customers depend on the reliability of redundant power systems housed in their facility.
The Dual Input PDUs ship with both 0U and 1U mounting brackets (no additional mounting
brackets need to be purchased).
*The number of outlets vary by model, please refer to the Table 8 for more specific information.

Note 1: This PDU supports power from two different sources. If one power source fails, the PDU uses the alternate source.
Note 2: This PDU must be hardwired to the power source by a certified electrician.

G3 power calculator at
activeanswers.compaq.com/aaconfigurator/PowerCalc/DL360Generation 3.xls
figuring type and number of pdu’s
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.
HP PDUs support both high-voltage and low-voltage applications. The input current rating for a
ProLiant DL360 Generation 3 server is either 1.7 A at 200 to 240 V or 3.7 A at 100 to 120 V. To
determine the number of servers supported by a PDU, divide the PDU’s current rating by the
server’s total input current rating.

hp ProLiant DL360 generation 3 server high-density deployment technical white paper 11
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 1.7 A at 208 V.
24 A (PDU current rating) / 1.70 A (server total input current rating) = 14
This PDU can support a maximum of 14 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 3.7 A at 100 V.
24 A (PDU current rating) / 3.70 A (server total input current rating) = 6
This PDU can support a maximum of 6 servers at full server input current ratings.

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 used to support a known number of 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 14 servers. Each server can be allocated
1.71 A. If the line voltage is assumed to be at 208 V, then the allocated input power budget for
each server will be (1.71*208) = 356 W.
Since the input power budget of 356 W exceeds the fully configured system measured input
power of 292 W (as shown in Table 2), 14 ProLiant DL360 Generation 3 servers can be
supported by a 24 A high-voltage PDU. That means, three of these PDUs are needed to support
42 servers in a 42U rack.
selecting server power cords
To select the appropriate server power cord, check 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.

hp ProLiant DL360 generation 3 server high-density deployment technical white paper 12
power cords
The ProLiant DL360 Generation 3 server ships with an IEC-IEC power cord (P/N 142257-003)
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. and Japanese models will ship with two power cords - IEC-IEC and country-specific cord.
high-voltage Y-cables
The Vertical-Mount PDU Bracket with a High-Voltage Cables kit includes 1 Y-cable. 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 DL360 Generation 3 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.

A KVM (keyboard, video, and mouse) console management system enables a single keyboard
and video console to control multiple servers. An in-rack console management system may be
used to manage a single rack of servers or groups of racks. The HP IP console switch products
have 16 ports that can access up to 128 servers. The HP IP Consoling Solution combines analog
and digital technology to provide flexible, centralized KVM control of data center servers. This
solution provides enterprise customers with a significant reduction in cable volume, secure
remote access, and high-performance server KVM access. Using the IP console viewer, users can
access local KVM functions from any Windows or Linux workstation by means of a 10/100
network connection. Alternatively, an off-rack console management system may also be used in
the local vicinity of the servers it manages.

In-Rack Local IP Consoles
With an in-rack local console, all equipment, servers, switchboxes, keyboards, keyboard drawers,
and video displays are installed together in the same rack. The HP switchboxes mount behind the
keyboard drawer and don’t consume extra U-space in the rack. Using the TFT5600 RKM and an
IP console switch will consume a total of 1U to accommodate up to 128 servers. One console
switchbox can support up to 16 directly attached servers with no user blocking. Up to eight
servers may be tiered or cascaded on each switch port using either a legacy Compaq KVM switch
or an Expansion Module; however, only one user can access tiered switches or servers connected
by Expansion Modules at any one time. Critical devices requiring frequent access should be
attached directly to a switch port. Server accessibility should be assessed by the IT manager prior
to deployment to determine the appropriate server density per console switch.
Table 9 outlines the number of devices that fully populate a 47U, 42U or 36U rack with an in-rack
local console.

planning rack configurations
There are several important factors to consider when planning a rack configuration:
• The number of servers deployed in the rack

hp ProLiant DL360 generation 3 server high-density deployment technical white paper 16
• 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 and upgrade
requirements, and installation requirements.
weight considerations
Table 10 lists the weight and power specifications for Compaq branded 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 servers. See the
following example:
1 ×10642 rack 114 kg/253 lb
36 ×ProLiant DL360 Generation 3 server
with hard disk drives (16 kg/37 lb each)
604 kg/1,332 lb
36 ×Cable management system 76 kg/168 lb
2 ×High-voltage PDUs with brackets 17 kg/38 lb
18 ×High-voltage Y-cables 9 kg/21 lb
36 ×Keyboard/Video/Mouse cables 27 kg/59 lb
Total configured rack weight 848 kg/1,871 lb
IMPORTANT: Populate a rack with ProLiant DL360 Generation 3 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 branded racks
Use the following considerations as guidelines for the ProLiant DL360 Generation 3 server.
WARNING: Follow these guidelines to reduce the risk of personal injury or damage to
the equipment:
• Do not install a ProLiant DL360 Generation 3 server into a rack until the rack has
been placed in its final location.
• Preinstall 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
before 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
771 kg (1,700 lbs). 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 Generation 3 server in a Compaq branded 7000-series
rack, replace the front door of the rack with the High Air Flow Rack-Door. Install the door 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 Compaq branded 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
The ProLiant DL360 Generation 3 server design supports deployment in many environments. The
server ships standard in a Universal Rack Rail that works in both round-hole and square-hole 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 in) to 787 mm (31 in) 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 optional 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 branded or third-party racks. The sliding rack rails compress and snap securely in place
in the rack without screws or nuts.

hp ProLiant DL360 generation 3 server high-density deployment technical white paper 19
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.
Refer to the HP ProLiant DL360 Generation 3 Setup and Installation Guide for complete
installation instructions.
telco rack solution
Many data centers use two post telecommunication (telco) racks. The ProLiant DL360
Generation 3 server design supports deployment in telco racks. HP offers a telco rack kit designed
to install ProLiant DL360 Generation 3 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 server. Before deploying the servers into a telco rack, remove
the standard server rails and replace them with the telco server rails included in the telco rack kit.

configuration A: maximum performance density
(42 servers, high-voltage)
This configuration (Figure 2) shows a “best practice” for a 42U rack with 42 servers in a
high-voltage facility where a deployment plan can accommodate the derating of each ProLiant
DL360 Generation 3 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 2 x 40 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. Therefore, the allocated maximum input power for each server
will be:
1.905 A * 208 V = 396 W
Since the maximum measured input power per server is 352 W, 352 W will be used to calculate
the maximum thermal dissipation per server. It will be:
352 W * 3.41 = 1200 BTUs/hour
For 42 servers, the total thermal dissipation will be 1200*42 = 50,414 BTUs/hour.
In the “Measured Input Power” section of this document, a fully configured system was measured
to consume lower than 352 W (Table 3, server configuration 4). If each derated server
configuration input power is lower than 396 W, then 42 servers can be supported via this
configuration summary (Table 12).
