Abstract
This white paper is intended for use as a planning guide to expedite the concentrated
deployment of several HP ProLiant DL380 Generation 3 servers. Use this white paper in
conjunction with other documents for the server and 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. HP meets this
need with the density-optimized line of ProLiant servers, such as the ProLiant DL380
Generation 3 server. At a height of 2U each, up to 21 servers can fit in a single 42U
rack. While this server has clear space-saving benefits, its compressed size presents new
challenges for rapid server deployment, as well as cable management and
environmental considerations.
HP engineers have developed innovations in rapid high-volume deployment and
improved cable management for large installations of ProLiant DL380 Generation 3
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 rack configurations, such as keyboard,
video, and mouse infrastructure.
IMPORTANT: This document principally discusses the ProLiant DL380 Generation 3 server,
the HP branded or Compaq branded 7000-, 9000-, and 10000-series racks, and related rack
options. This document does not discuss other HP servers or products or racks not manufactured
by HP.

Server Warnings Adhere to the following guidelines when servicing or installing an HP server:
WARNING: To reduce the risk of electric 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 in) 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 mi
g
ht become unstable and cause serious personal in
j
ur
y
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 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.
Note: Sliderails, power distribution units (PDUs), power cords, and cables can be preinstalled
into the rack in a build room or on the data center floor before moving the rack to its final
ocation.l

Introduction HP designed the dense ProLiant DL380 Generation 3 server to meet the challenges associated with
deploying a high concentration of servers in a single rack. HP suggests that customers evaluate their
environments, power distribution, console, cable, and thermal management choices well in advance
to ensure efficient deployments.
All discussions of power requirements for this server are based on the input power of the server. This
document uses the maximum rated power supply input of 200 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.
IMPORTANT: In this document, de-rating the input power budget means using less than the maximum
rated input power values for the power supply. HP strongly recommends using the installation planner to
ensure that the derated power budget will satisfy all the installation requirements, including future
upgrade plans.

Power and
Thermal Budgeting
This section provides the information and worksheets necessary to calculate power and thermal
budgeting for system. However, for the most accurate, updated power and thermal budgeting
calculations for your particular configuration, HP recommends using the online power calculator.
To use the calculator, visit the Active Answers website:
http://activeanswers.compaq.com/ActiveAnswers/Render/1,1027,1-6-100-225-1,00.htm
Note: In this document, derating the input power budget means not using the maximum rated input power
values for the power supply. HP strongly recommends using the installation planner to ensure that the
derated power budget will satisfy all the installation requirements, including future upgrade plans.
All 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. One of
the following methods can be used to account for input power in the facility power distribution
planning:
• Use the maximum power supply rated input AC power.
• Use the derated input power, which can be calculated by subtracting the power budgets of
uninstalled optional components from the rated input power.
• 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 the maximum system
configuration power 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. These configurations
measured range from a basic low-end configuration to a fully populated high-end configuration.
Since the input power values used 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 400 W. Assuming the power supply
efficiency of 71% (including the Power Factor Correction), the power supply input power is rated
at 565 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.
The input power requirement might be lowered in the following instances:
• 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 cooling requirements with the existing facility environment.

Table 4 demonstrates how calculating the derated input power of the system can significantly reduce
input current and thermal dissipation.
Table 4. Derated Current and Thermal Dissipation for Reduced input Power Assumptions
Input Power Derated Full Rating
Minimum Configuration Maximum Configuration
Input Power at 115 VAC 1.9 A 4.1 A 4.9 A
Input Current at 240 VAC 0.9 A 1.8 A 2.3 A
Thermal Dissipation 747 BTUs/hour 1560 BTUs/hour 1927 BTUs/hour
The derated input power values of the maximum and minimum configuration wattages can be
correlated with the measured input power values for the minimum and maximum configurations of the
server. However, the derated input power value must be high enough to account for any future
upgrades.
As stated earlier, the power supply is designed to support future processor and hard drive upgrades.
When installing 21 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 the deployment
needs and reduce the numbers of PDUs per rack. Reducing the number of PDUs has a direct impact
on the deployment time and maintenance of an installation.
The remainder of this section explains the input power relationships to input current and thermal
dissipation to aid customers in derating the input power.

Input Current and
Thermal
Dissipation
Calculations
Input power is the key in deriving 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 spin ups of the hard drives. It should be
noted that in the server, 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 II option, NICs, and so on.
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, then multiply the total input
power by 3.41. The total thermal dissipation helps determine cooling and environmental
requirements for the populated rack.
The “Measured Input Power” section explains more on how adding or removing of an optional
subsystem component affects the input power and thermal calculations.

Power
Table 5 lists the measured input power of the server with varying subsystem components, to illustrate
the effects of adding or removing optional components. The “typical” input power values were

Input Power
Budget Derating
If a deployment plan limits the future expansion beyond certain configuration options, 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 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 7 to calculate the derated power
budget using the typical power from Table 5.
Processors: 2 x 2.4 GHz
Memory: 4 x 512 MB
Storage: 2 x 18.2 GB
Table 7. Example of Derating Worksheet
1. Start with the maximum rated input power for the base configuration
(1 processor, 2 DIMMs, 0 hard drives)
207 W
2. Add the typical power for the second processor +40 W
3. Add the typical power for the additional memory +4.8 W (2.4 W per DIMM)
4. Add the typical power for the additional storage
Typical power for the desired configuration
+ 38 W (19 per hard drive)
= 290 W
5. Calculate the thermal dissipation
Thermal dissipation for the desired configuration (in BTUs)
×3.41
989 BTUs/hour
Therefore, the new power budget for this configuration is 290 W (compared to the rated 565 W),
and the thermal dissipation is approximately 989 BTUs/hour (compared to the rated 1927
BTUs/hour).
The rated input power for the server power supply is 565 W. Therefore, the power budget for a
maximum configuration is 565 W, and the thermal dissipation will be approximately (565*3.41=)
1927 BTUs/hour.
This derated input power budget significantly reduces the power and thermal requirements for highly
populated racks, which reduces the number of PDUs for certain configurations. Fewer PDUs decrease
deployment time and lower costs. Costs for the facility electrical plumbing, data center floor
ventilation, and facility air conditioning installation can also be reduced.
IMPORTANT: HP strongly recommends verifying that the derated power budget satisfies all the
installation requirements, including future upgrade plans.

HP ProLiant DL380 Generation 3 Server High-Density Deployment
15
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 supports 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 by 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 12 servers. Each server can be allocated
2.0 A. If the line voltage is assumed to be at 240 V, then the allocated input power budget for each
server will be (2.0*240) = 480 W.
Since the input power budget of 480 W satisfies the fully configured system measured input power
of 458 W (as shown in Table 5), 12 servers may be supported by a 24 A high-voltage PDU.
Power Distribution
Units
HP offers a wide range of 1U/0U PDUs, supporting both low-voltage and high-voltage applications.
Designed for high-volume rack deployments, HP PDUs help with 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 16A to 40A and provide up to 32 outlets, easy accessibility,
and improved cable management. These mPDUs have a unique modular architecture, allowing
increased flexibility and customization. All mounting hardware, including both the 0U and 1U
mounting brackets, is included in the Modular PDU kit.
Additionally, HP offers the Dual Input PDU, a fault-tolerant solution that automatically switches 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).

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 hard-wired to the power source by a certified electrician.
Note 3: This PDU is using the maximum rated power supply input and not the derated values.
Figuring Type and
Number of PDUs
The type and number of PDUs required to power a full rack of servers depends on the power
requirement for each server, 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 DL380 Generation 3 server is either 2.3 A at 240 volts or 4.9 A at 115 volts. To determine
the number of servers supported by a PDU, divide the current rating of the PDU by the total input
current rating of the server.
IMPORTANT: The examples shown in the following sections use the maximum rating of the power supply.
They are for reference only.

HP ProLiant DL380 Generation 3 Server High-Density Deployment
17
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 has a current rating of 24 A. The server has a total input current
rating of 2.3 A at 200 volts.
24 A (PDU current rating)/2.3 A (server total input current rating) = 10.4
This PDU can support a maximum of 10 servers at full server input current ratings.
Example
One low-voltage PDU has a current rating of 24 A. The server has a total input current rating
of 4.9 A at 100 volts.
24 A (PDU current rating)/4.9 A (server total input current rating) = 4.9
This PDU can support a maximum of 4 servers at full server input current ratings.
Redundant Power
The server supports a redundant power supply. The power supply for this server automatically senses
input voltage level. Under normal operation, the two power supplies load share with each power
supply supporting 50% of the load of the server. When one power supply or power source fails, the
remaining power is capable of supporting the entire load of the server.
Likewise, when configuring a rack of servers for redundant power feeds, the PDUs should only be
loaded to 50% of its rated capacity while supporting no more than 50% of the load of the rack
under normal operation. If one of the power feeds fails, the PDU would still have sufficient capacity
to support the entire load of the rack.
CAUTION: When loading a PDU in a redundant configuration, never exceed 50% of the rated
capacity of the PDU under normal operation. If the PDUs are loaded beyond 50% and one power
feed or PDU fails, the remaining PDU will trip due to overload and the entire rack will lose power.
When planning a configuration with redundant power supplies for redundant feed, the calculations
should be performed as if only one feed was being supplied. Then, the resulting PDUs and power
infrastructure components for the rack should be doubled.
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 1.83 m (6 ft)
in length. This length provides enough slack for the power cord to route through the cable
management solution.

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. Refer to 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 the Vertical-Mount PDU Bracket kit may be still be used if needed.
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 servers in the standard configuration or one 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.

The IEC-to-IEC cables can be used either as individual
power cords to connect PDUs or to extend the length of
the high-voltage Y-cables. The server ships with one
3.0-m (10-ft) IEC-to-IEC cable, part number
142263-003.
Power Cords The server ships with an IEC-to-IEC power cord (PN 142263-003) used for rack mounting with high-
voltage PDUs. For low-voltage, stand-alone deployments or installation without a rack, country-
specific power cord options are available.
U.S. and Japanese models ship with two power cords—IEC-to-IEC and a country-specific cord:
• Power cord, US, IEC320-C13 to IEC320-C14, 10 A 250 V, Straight (3 m/10 ft)
(PN 142257-002)
• Power cord, US, IEC320-C13 to NEMA 5–15P, 15 A 125 V, Straight (3 m/10 ft)
(PN 103541-001)
The power cord included with the North American model of the server can be used for low-voltage
applications. Use a 1.8-m (6-ft) to 2.4-m (8-ft) long power cord with the standard rack rails and cable
management arm.

Console
Management
Systems
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
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 TFT5600RKM 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 before
deployment to determine the appropriate server density per console switch.

Each server deployed in a fully populated rack with an in-rack IP console management system
requires the following accessories for successful deployment and operation:
• Interface adapter
• UTP CAT5 cable [1.8 m (6 ft) cables for sliding rail solutions]
• Rack Rail kit (standard rack rails and cable management arm, telco rack solution, or roundhole
rack rails and cable management arm)
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 round-hole
rack rails and cable management arm)
• KVM server to console cables
• One or two RJ-45 cables for NIC 1 and NIC 2
Remote Console
Management
Integrated Lights-Out (iLO) is a standard component of selected ProLiant servers that provides server
health and remote server manageability. The iLO subsystem includes an intelligent microprocessor,
secure memory, and a dedicated network interface. This design makes iLO independent of the host
server and its operating system. Integrated Lights-Out provides remote access to any authorized
network client, sends alerts, and provides other server management functions. For information about
iLO features, refer to the Integrated Lights-Out User Guide on the Documentation CD or at
www.hp.com/servers/lights-out.
