Abstract: A method and an information handling system (IHS) determine optimum ambient temperature conditions for targeting desired system cooling constraints. According to one aspect, a target parameter recommendation module (TPRM) receives a target cooling parameter value for a number of servers having an identified configuration. The TPRM identifies an acceptable range of ambient conditions, corresponding to the received target parameter value(s). The TPRM determines via a series of iterations whether the target parameter value is attainable using the acceptable range of ambient conditions. If the target parameter value is attainable, the TPRM provides a first notification identifying ambient conditions by which the target parameter value can be attained. However, if the target parameter value is not attainable using the acceptable range of ambient conditions, the TPRM provides a second notification recommending an adjustment to server cooling constraints and/or the identified system configuration.

The airflow delivery target is scaled based on the installed location of the new component. The airflow cooling system is operated to equalize the estimated airflow delivery to the new component with the airflow delivery target for new component.

Abstract: A computer-implemented method enables Basic Input/Output System (BIOS) progress code based thermal control during start-up of an information handling system (IHS). A start-up thermal control sub-system (i) determines an initial cooling level for use during a pre-BIOS progress code operation state of the IHS, (ii) detects each BIOS progress code provided during a boot loading operation of the IHS, and (iii) determines whether a detected BIOS progress code has an associated cooling level requirement that is different from a current cooling level provided by one or more cooling devices of the IHS. In response to the detected BIOS progress code having an associated cooling level requirement that is different from the current cooling level provided by the one or more cooling devices, the one or more cooling devices are triggered to adjust the current cooling level to a next pre-established cooling level associated with the detected BIOS progress code.
