Data center management system that controls environmental conditions to facilitate operating state changes of individual equipment
A management system controls environmental conditions to facilitate operating state changes of individual information technology (IT) equipment within a data center. A management controller accesses a specification data structure containing environmental conditions specified to enable each one of the IT components to function in operational operating state(s). The management controller determines a temperature range specified in the specification data structure for a first IT component that is scheduled to transition into a first operational state. The management controller adjusts a temperature set point of supply air provided by the data center to the first IT component to be within the temperature range. In response to determining that the interior air temperature is within the temperature range, the management controller triggers activation of the first IT component into the first operating state.
