Just been ''researching'' on the net for some datacenter calculators, and come across this from APC's Data Center Science Center.

The seven tools are currently available on the tools.apc.com
section of the APC Web site. They include:

Carbon Calculator

Illustrates how changes to a data center's location, efficiency, and power
load can impact carbon dioxide emissions and the electric bill. This
provides management with a general indication of how "green" their data
center is today and how "green" it could be.

Energy Efficiency Calculator

Profiles a data center and calculates the resulting efficiency and
electrical cost based on data center characteristics. Users can then
understand the impact each key data center decision has on the data
center's efficiency.

Capital Cost Calculator

Identifies key data center physical infrastructure parameters and
calculates capital costs based on those parameters. This allows data
center users to judge how changes to data center location, IT load, and
cooling and power infrastructure can impact overall capital costs.

Virtualization Energy Cost Calculator

Comprehends IT and physical infrastructure characteristics and calculates
energy savings resulting from the virtualization of servers. This allows
the user to test the impact of virtualization and various physical
infrastructure improvements on their data center floor space and on their
energy consumption.

Power Sizing Calculator

Defines basic characteristics of the IT load and calculates how much
utility input power would be required to support such a load. This
provides users with a general idea of how much power in kilowatts they
will need to run their data center.

InRow(TM) Containment Selector

Generates a prototype rack and row cooling configuration based on the
user's preferences and the physical constraints of the room. This provides
the user with their optimal InRow cooling containment configuration.

AC vs. DC Calculator

Compares four different AC and DC power distribution architectures and
calculates their respective efficiencies. This allows the user to make an
educated decision on the optimal architecture for their data center.


APC's Data Center Science Center (DCSC) designed the APC TradeOff Tools.
The DCSC team of engineers and analysts researches data center issues and
helps develop design and learning tools that assist data center
professionals in managing their data centers. For more information about
APC and the TradeOff Tools, please call 800-877-4080 or visit APC's Web
