ABSTRACT:
A mechanism for controlling the hardware resources on a blade server, and thereby limiting the power consumption of the blade server is disclosed. The enforceable hardware resources that are controlled include the base frequency of the central processing unit (CPU) as well as power to individual banks of physical memory, for example dual-inline memory modules (DIMMs). The hardware resources are tuned in dependence on actual server utilization such that applications running on the blade only have the allocated hardware resources available to them. Deactivated hardware resources are powered off and are so ‘hidden’ from the operating system when they are not required. In this manner, power consumption in the entire chassis can be managed such that all server blades can be powered on and operate at higher steady-state utilization. The utilization of the powered on resources in a blade center is also improved.
