6. The method of claim 4 , further comprising:

determining, for each placement configuration of the one or more of the plurality of placement configurations, that the determined airflow for each of the plurality of sleds is greater than or equal to the airflow threshold for each respective sled of the plurality of sleds.

7. The method of claim 1 , wherein the method is performed by an embedded controller of the information handling system.
