Compaq ProLiant DL320

Ultra-Dense Server Deployment

in Compaq Racks

Abstract: This white paper is intended for use as a planning

guideline to expedite concentrated deployments of several

Compaq ProLiant DL320 servers in a Compaq rack. Use this white

paper in conjunction with documents for the ProLiant DL320 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 of the network infrastructure and web applications that

business enterprises and service providers use work best on

dedicated servers, creating the need to fit a large number of smaller

servers into existing server rooms and data centers. Compaq fulfills

this need with the density-optimized line of ProLiant servers such as

the ProLiant DL320. At a height of 1U each, up to 42

ProLiant DL320 servers can fit in a single Compaq rack. While the

space-saving benefits of this server are clear, the compressed size of

the ProLiant DL320 presents new challenges for rapid deployment of

servers into a rack, 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 DL320 servers. This white paper introduces planning

considerations, power distribution units, server and rack

requirements, and installations. It also outlines the products

associated with high-volume deployment in Compaq rack

configurations.

IMPORTANT: This document discusses only the ProLiant DL320

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.

PAGE 41
Compaq ProLiant DL320 Ultra-Dense Server Deployment in Compaq Racks 41 Appendix C – Power and Thermal Budgeting All power requirements for ProLiant DL320 servers that are discussed in this document are based on the input power of the server. Compaq recommends using the maximum rated power supply input of 200 W when planning power distribution.
PAGE 42
Compaq ProLiant DL320 Ultra-Dense Server Deployment in Compaq Racks 42 Input Current and Thermal Dissipation Calculations The input power is necessary for determining the input current and thermal dissipation. For a given input power, the input current varies 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.
PAGE 43
Compaq ProLiant DL320 Ultra-Dense Server Deployment in Compaq Racks 43 Measured Input Power Table 21 lists the measured input power of the ProLiant DL320 with varying subsystem components to illustrate the effects of adding or removing optional components. The “peak” and “typical” input power values were measured during power-up and idle/normal operations, respectively. Table 21.
PAGE 44
Compaq ProLiant DL320 Ultra-Dense Server Deployment in Compaq Racks 44 Input Power Budget Derating This section explains how to derate the input power budget. The maximum rated power supply input power is 200 W. To derate the input power, start with the base configuration 0 from Table 21. Add the peak power of the components included in the desired system configuration to calculate the derate d power budget. Typical and peak input powers for various components are listed in Table 22.
