Supercapacitor-based power supply protection for multi-node systems

A system comprising:

• a plurality of compute nodes to couple in a chassis, the plurality of compute nodes comprising a plurality of servers;
• a first shared power supply to provide power to the plurality of compute nodes via a power bus, the first shared power supply to provide a baseline power level to the plurality of compute nodes;
• and
• an auxiliary power source to provide power to one or more of the plurality of compute nodes via the power bus when the one or more of the plurality of compute nodes are to operate at a higher power level than the baseline power level;
• wherein the auxiliary power source is to store at least an energy corresponding to a difference between a maximum peak power level of the plurality of compute nodes and the baseline power level of the plurality of compute nodes multiplied by a duration of the maximum peak power level.

A system comprising:

• a plurality of compute nodes comprising a plurality of servers;
• a first shared power supply to provide power to the plurality of compute nodes, the first shared power supply to provide a baseline power level to the plurality of compute nodes that is insufficient to accommodate a maximum peak power of the plurality of compute nodes;
• an auxiliary power source to provide power to one or more of the plurality of compute nodes when the one or more of the plurality of compute nodes are to operate at a higher power level than the baseline power level, the auxiliary power source adapted to store energy to supply a difference between the maximum peak power and the baseline power level;
• a platform controller coupled to the plurality of compute nodes via a management interconnect, the platform controller to output a thermal event assertion comprising an over temperature signal to the plurality of compute nodes in response to a discharge event of the auxiliary power source, without detection of a thermal event;
• wherein at least one of the plurality of compute nodes includes a power controller to receive the thermal event assertion from the platform controller and cause a reduction in a power consumption of the at least one of the plurality of compute nodes in response to the thermal event assertion;
• and
• wherein the auxiliary power source is to store at least the energy corresponding to the difference between the maximum peak power and the baseline power level multiplied by a duration of the maximum peak power.
