Managing server performance and reliability during reductions in a number of power supply units

Abstract:

Techniques are disclosed regulating an amount of power consumed by a server from a set of power supplies in which at least one power supply of the set is inactive. The power to a server, upon detecting that at least one power supply is inactive, is restricted based on a degree to which a power threshold value for the remaining power supplies is exceeded. The applied power reduction may be based on a proportion of a measurement interval during which an alert signal is received. The longer the alert signal is received by the system, the more server power consumption is reduced.
