Estimating power and cooling

Power consumed by a c-Class BladeSystem solution is converted to heat, which is expressed in British thermal units per hour (BTU/h). You can calculate the heat load for a system by using the following equation: Heat Load = Power (Watts) x 3.413 BTU/h.

In the preceding equation, 1 W equals 3.413 BTU/h. A c7000 enclosure fully loaded with dual-socket server blades, with dual-core processors might use 5 kW of power, thereby generating almost 17,000 BTU/h. The installation of a c-Class BladeSystem solution into a computer room containing existing systems might have a significant impact on cooling requirements. HP Data Center Services provides consultation to assist you in developing an efficient high-density cooling strategy by using dynamic modeling.

For more information, contact your HP sales representative.

A complete discussion of cooling requirements is beyond the scope of this guide. For more information, see the following sources:

•Technology Brief TC050901TB Optimizing data centers for high-density computing, 2nd edition available on the HP website (http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00064724/c00064724.pdf).

•Best practices for HP 10000 Series and HP 10000 G2 Series Racks, available on the HP website

(http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00883424/c00883424.pdf).

Modern blade systems should budget at least 4 kW of actual power use per enclosure at maximum configuration. Using modern day kW/cabinet to W/sf conversion ratios this equates to ~ 90 W/sf for each single blade server chassis.

Placing just three server blade chassis systems into a rack equates to a power density of at least 250 W/sf. When planning upgrades to older data centers to add server blades, plan to upgrade the electrical and mechanical infrastructure to properly support the added electrical and cooling requirements. New datacenter planning for bladesystems must specify a minimum of 250 W/sf or 12 kW/cabinet power densities.

To estimate computer-room cooling requirements, first calculate the amount of energy used by the solution. HP provides online power-consumption calculators that enable you to configure a virtual rack and determine its power consumption. See the HP website (http://www.hp.com/go/bladesystem/powercalculator).

For other models, obtain the power consumption data from a component's specifications.

The QuickSpecs contains the specifications for all HP products. Photocopy the following worksheet and use it to calculate power consumption and heat load.
