Figure is based on a fully loaded 42U rack with maximum configurations, typical power consumptions, and a heat load based
on square footage of the equipment footprint.

Using sizing tools to understand server and facility requirements

Data center sizing tools are available to address both small-to-medium size business requirements and
enterprise business requirements. These tools can provide power and computational workload
estimates for both rack-mounted servers and server blades. Available sizing tools also address data
center storage requirements and remote management implementations. These tools are typically
produced by each hardware vendor. HP tools include the HP Power Calculator utility, the HP
BladeSystem Power Sizer, the HP StorageWorks Sizing Tool, and the HP Systems Insight Manager
(SIM) sizing tool.
The HP Power Calculator utility enables IT planners to more accurately estimate the power needs of
HP ProLiant systems. The calculator provides meaningful estimates of power requirements for sizing an
infrastructure. It is important to note, however, that actual power consumption of an installed system
running certain applications may vary. The calculator is available as a Microsoft® Excel®
downloadable, interactive catalog at http://h30099.www3.hp.com/configurator/calc/Power
Calculator Catalog.xls.
The HP BladeSystem Power Sizer enables the facilities team to effectively plan for the power
consumption and heat load of an HP BladeSystem. The tool is based on actual, component-level
power measurements of a system stressed to maximum capability.
The HP StorageWorks Sizing Tool provides information for designing a storage infrastructure. This
downloadable sizing tool applies storage design rules, licensing, and services rules to design the
system.
