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.
