Blade Power Calculators
March 3rd, 2008 | 
Author: Aaron Delp’s BladeVault.info site reports about calculators from HP and IBM that can help you plan for power when considering physical server consolidation by implementing blades. IBM’s calculator is a downloadable .msi while HP’s is an online calculator. HP also offers a downloadable offline version which has limited functionality compared to the online tool. IBM’s calculator is not just limited to blades as it computes power figures for all x series servers.
IBM System x and BladeCenter Power Configurator
From http://www-03.ibm.com/systems/bladecenter/resources/powerconfig/index.html:
“Energy costs are top of mind in IT today. In fact, it is estimated that each year companies pay a significant part of the purchase price of a system on powering, cooling, and housing that system.
That’s why IBM is delivering new technologies that allow our blades to use less power, generate less heat, and use less energy to cool the system than the competition. Simply put, the IBM System x and BladeCenter ‘runs cooler’ to deliver greater reliability and uses as much as 37% less energy than competitive Blades1
Take the Power Challenge using the IBM System x and BladeCenter Power Configurator, and discover the energy savings a BladeCenter can bring to your business.”
HP BladeSystem Power Sizer
From http://h71019.www7.hp.com/ActiveAnswers/cache/347628-0-0-0-121.html:
“The HP BladeSystem Power Sizer assists facilities teams and IT staff in sizing their power infrastructure to meet the needs of an HP BladeSystem solution. Based on actual component level power measurements of a system stressed to maximum capability the BladeSystem Power Sizer enables the facilities team to effectively plan for the power consumption and heat load of an HP BladeSystem.
The sizer allows a customer to select the type and number of components within each Blade Server and Blade Enclosure and see the effect of the changes on the power consumption and heat loading.
Values obtained from the BladeSystem Sizer tool are measured with all components stressed to 100% load and is intended for facilities planning purposes only. Actual power consumption will vary with application type, application utilization and ambient temperature.
c-Class BladeSystem solutions are now supported in the BladeSystem Power Sizer.
