Method for pre-chassis power multi-slot blade identification and inventory
First Claim
1. A method of operating an information handling system which comprises a plurality of blade components and a chassis controller, comprising:
- obtaining pre-set information handling system limitations;
providing low power auxiliary power to the plurality of blade components within the information handling system;
selectively powering only a portion of at least one of the plurality of blade components in a low power state, the portion of the at least one of the plurality of blade components being sufficient to communicate information regarding a first blade component of the plurality of blade components to a chassis controller;
communicating the first blade component information to the chassis controller while the low power auxiliary power is provided to the first blade;
scanning a multiple of the plurality of blades components while low power auxiliary power is provided to the multiple of the plurality of blade components to identify blade information, the scanning occurring before a power on request to fully power on is provided to a scanned blade;
selectively bypassing the scanning of at least one of the blade components of the information handling system based upon the blade information regarding the information handling system limitations; and
terminating the providing of low power auxiliary power to the scanned blade before the request to fully power on the scanned blade is made.

Abstract
Systems and methods for a blade server to obtain the blade type and configuration of the chassis without requiring the blades to be fully powered. Using this method the user has the ability to acquire correct inventory and slot status of the chassis through the use of a low power auxiliary power state. The user is then able to apply the proper power budgeting and thermal algorithm requirements utilizing this information while minimizing the power consumption necessary to acquire such information. In addition, an intelligent search algorithm may be utilized to scan the blades for blade information thus further minimizing power consumption and decreasing the time needed to inventory the blades.
