Examples disclosed herein relate to power management in a blade enclosure. An intrusion detection mode is initiated by a baseboard management controller. Responsive to determining a power shortage in the blade enclosure, a stop clock pin is operated to control power consumption of a server in the blade enclosure. After a predefined time of determining the power shortage, a model specific register (MSR) associated with power settings of a Central processing unit (CPU) of the server is reconfigured. Reconfiguring the MSR comprises, identifying a power profile based on available power in the blade enclosure and modifying register states in the MSR based on the power profile via a baseboard management manager (BMC) of the server. Subsequently, operation of the stop clock pin is stopped.

Power management in a blade enclosure

In at least some embodiments, a system comprises a processor and a memory coupled to the processor. The memory stores processor performance utility instructions and performance adjustment instructions. When executed, the processor performance utility instructions are configured to cause activities of the processor to be counted and to cause a processor utilization value to be determined based on the counts. When executed, the performance adjustment instructions are configured to adjust the processor utilization value based on a comparison of the processor's current operating frequency and maximum operating frequency.
