Systems and methods for in-situ fabric link optimization in a modular information handling system chassis

A method comprising, during boot of a modular information handling system disposed in a chassis configured to receive a plurality of modular information handling systems and a plurality of modular information handling resources:

• pausing execution of a basic input/output system;
• communicating a first indicator, wherein the first indicator causes a chassis management controller of the chassis to perform link optimization operations of a communication link between the modular information handling system and a modular information handling resource;
• and
• in response to communication by the chassis management controller of a second indicator, the second indicator indicating completion of link optimization operations by the chassis management controller, unpausing execution of the basic input/output system.

An article of manufacture comprising:

• a non-transitory computer readable medium;
• and
• computer-executable instructions carried on the computer readable medium, the instructions readable by a processor, the instructions, when read and executed, for causing the processor to perform link optimization operations in a modular information handling system disposed in a chassis configured to receive a plurality of modular information handling systems and a plurality of modular information handling resources, the link optimization operations comprising:
• determining if a modular information handling resource disposed in the chassis and communicatively coupled to a modular information handling system disposed in the chassis is identified in a whitelist;
• if the modular information handling resource is identified in the whitelist, retrieving typical operating parameters associated with the information handling resource;
• if the modular information handling resource is identified in the whitelist, retrieving target operating parameters associated with the information handling resource;
• determining if actual operating parameters of a communication link between the modular information handling resource and the modular information handling system satisfy the typical operating parameters or the target operating parameters;
• and
• performing a remedial action if actual operating parameters of a communication link between the modular information handling resource and the modular information handling system do not satisfy the typical operating parameters or the target operating parameters.
