1. A method for managing the respective operating voltages of a plurality of respective blades within a bladed architecture system, said method comprising the steps of:
operating a first blade within said bladed architecture system at a first voltage level, said first blade hosting applications that require a first power allocation, wherein said first blade consumes a first portion of the thermal and power budget in said bladed architecture system based upon said first power allocation;
operating a second blade within said bladed architecture system at a second voltage level, said second blade hosting applications that require a second power allocation, wherein said second blade consumes a second portion of the thermal and power budget in said bladed architecture system based upon said second power allocation; and
maintaining the overall thermal and power budget in said bladed architecture system by modulating at least one of said first voltage level and said second voltage level, wherein said first voltage level and said second voltage level are unequal fractions of a total voltage allowance of said bladed architecture system and wherein said total voltage allowance is determined by the thermal and power budget allocation of said bladed architecture system.
