Embodiments include in response to monitoring a processor during operation, detecting a first number of throttling amounts in the processor, determining that the first number of throttling amounts fulfills a first condition regarding a throttling amounts threshold, and modifying a voltage level of the processor by a first amount. Embodiments include in response to modifying the voltage level of the processor by the first amount, detecting a second number of throttling amounts in the processor, determining that the second number of throttling amounts fulfills a second condition regarding the throttling amounts threshold, and modifying the voltage level of the processor by a second amount.

Embodiments include in response to monitoring a processor during operation, detecting a first number of core recovery events in the processor, determining that the first number of core recovery events fulfills a first condition for the first core recovery events threshold, and modifying a value of at least one droop sensor parameter of the processor by a first amount. The at least one droop sensor parameters affects a sensitivity to a voltage droop. In response to modifying the value of the droop sensor parameter by the first amount, a second number of core recovery events is detected in the processor. It is determined that the second number of core recovery events fulfills a second condition for a second core recovery events threshold, and the value of the at least one droop sensor parameter is modified by a second amount.

A cooling method is provided to remove heat generated by one or more electronic systems. The method includes providing a coolant-based cooling apparatus, redundant pumping units, redundant backup blowers, and multiple separate controllers. The cooling apparatus includes one or more heat exchange assemblies discharging heat from coolant of the cooling apparatus, and the redundant pumping units, which are coupled in parallel fluid communication, separately facilitate pumping of the coolant. The redundant backup blowers are disposed to provide, when activated, backup airflow across the electronic system(s). The multiple controllers control operation of the redundant pumping units and redundant backup blowers based, at least in part, on one or more sensed parameters. The redundant backup blowers are activated responsive to the sensed parameter(s) exceeding a set threshold to provide backup cooling to the electronic system(s) in the event of degraded performance of the cooling apparatus or the redundant pumping units.

Multi-level redundant cooling system for continuous cooling of an electronic system(s)

A method and system of cooling hardware, sensing hardware, and supporting code streams that enables a non-redundant liquid cooling system to be used seemlessly in conjunction with an air cooling backup solution. The result offers system speed and reliability benefits of liquid cooling except for the brief occasions when the primary cooling system has failed and air cooling takes over. Until the liquid cooling is repaired, system clocks are automatically slowed to be compatible with the circuit speeds possible at the higher temperatures associated with air cooling. When the liquid cooling is repaired, the system clocks are automatically returned to their normal fast state. Depending on the circuit technology used, a supplied voltage may be varied while being air cooled.
