A voltage regulation system for use with a multiple processor apparatus having a plurality of processors, comprising:
- a power converter;
- a plurality of voltage regulation modules (VRMs) coupled to said power converter and said plurality of processors, each one of said plurality of VRMs dedicated to only one of said plurality of processors wherein one of said plurality of processors is powered down in response to a failure of said respective dedicated one of said plurality of VRMs.
A method of voltage regulation for use with a multiple processor apparatus having a plurality of processors, comprising the steps of:
- providing a plurality of voltage regulation modules (VRMs) coupled to a power converter;
- dedicating each one of said plurality of VRMs to only one of said plurality of processors;
- and
- powering down one of said plurality of processors in response to a failure of said respective dedicated one of said plurality of VRMs.
