whitepaper Experts Speak on UPS Output Watt, VA, and Power Factor Ratings2005-02-04 American Power Conversion (APC)
  Over the past several years, electrical requirements of computer systems have changed - dramatically. Unfortunately for consulting engineers, computer users and facility engineers, many UPS system designs have not kept pace with these changes. In this paper, experts speak on the subject of UPS output ratings, and how the use of UPS with an output power factor rating of 1 reduces uncertainty of overloading the power system.

whitepaper Use of 208 Volt Verses 120 Volt Inputs for Servers2005-02-04 American Power Conversion (APC)
  208 Volts offers various technical advantages and is the only choice for higher power servers to be pluggable into standard NEMA outlets. Technically, 208V is a superior choice for powering computing equipment when compared with 120V due to lower current draw. However the ubiquitous nature of 120V wiring in North America and 100V in Japan make these lower voltages preferred by users. This white paper explains why and when 208V is used instead of 120V for servers in North America.

whitepaper Calculating Total Cooling Requirements for Data Centers2004-10-28 American Power Conversion (APC)
  All electrical equipment produces heat, which must be removed to prevent the equipment temperature from rising to an unacceptable level. Most Information Technology equipment and other equipment found in a data center or network room is air-cooled. Sizing a cooling system requires an understanding of the amount of heat produced by the equipment contained in the enclosed space, along with the heat produced by the other heat sources typically encountered. This document describes how to estimate heat output from Information Technology equipment and other devices in a data center such as UPS, for purposes of sizing air conditioning systems. A number of common conversion factors and design guideline values are also included.

whitepaper Monitoring Redundant Uninterruptible Power Supplies Using IBM Director2004-01-22 IBM
  Most UPS monitoring software assumes the server is communicating directly with, and getting power from, only one UPS. Larger UPSes have multiple communication ports or network ports to allow multiple servers to monitor the state of the UPS. This paper will discuss and demonstrate using IBM Director to monitor UPSes in this environment. It also covers the ability of IBM Director to shut down the appropriate systems, when necessary.
