Abstract:
1. A system for power management of a rack of computers, the system comprising: server side infrastructure (SSI) circuitry at each computer in the rack, the SSI circuitry including local monitoring circuitry coupled to a central processing unit (CPU) of the computer; and a centralized power management module (CPMM) with an out-of-band (OOB) management link to the SSI circuitry at each computer in the rack, wherein the CPMM is configured to monitor power being consumed by the CPUs by sending a polling message to the SSI circuitry at each computer in the rack, wherein the local monitoring circuitry within the SSI circuitry at each computer in the rack is configured to monitor power consumption and temperature at the CPU and to respond to the polling message from the CPMM by transmitting a power consumption value and a temperature consumption value to the CPMM, and wherein the CPMM is further configured to apply a set of rules to the power consumption and temperature values from the local monitoring circuitry to determine when and at which computers to enable and disable a CPU power throttling mode and when at which CPUs to apply thermoelectric cooling.
