System, method and apparatus for the frequency management of blades in a bladed architecture based on performance requirements
View Patent ↗In a system, method and apparatus for managing the operating frequency of blades in a blade-based computer system based upon performance requirements, a first blade that requires a specific power allocation is operated at a specific frequency and consumes a portion of the thermal and power budget for the blade-based computer system. A second blade that requires a specific power allocation is operated at a specific frequency and consumes a portion of the thermal and power budget for the blade-based computer system. Additionally, the overall power and thermal budget of the blade-based computer system is maintained.
1. A method for managing the operating frequency of blades in a blade-based computer system, said method comprising the steps of:
operating a first blade at a first frequency, said first blade hosting applications that require a first power allocation, wherein said first blade consumes a first portion of an overall thermal and power budget of said blade-based computer system based upon said first power allocation;
