Selecting between high availability redundant power supply modes for powering a computer system

摘要

Methods, apparatus, and products for selecting a redundant power supply mode for powering a computer system are disclosed that include detecting, by a voltage monitoring module, an input voltage level of a power supply; determining, by the voltage monitoring module, whether the input voltage level of the power supply is greater than a predetermined threshold value; if the input voltage level of the power supply is greater than the predetermined threshold value, configuring, by the voltage monitoring module, the power supply for an N+N redundant power supply mode having N primary power supplies and N redundant power supplies; and if the input voltage level of the power supply is not greater than the predetermined threshold value, configuring, by the voltage monitoring module, the power supply for an N+M redundant power supply mode having N primary power supplies and M redundant power supplies, where N is greater than M.
