A method, an apparatus, and computer instructions are provided for determining data center resource availability using multiple time domain segments. A reservation class is provided that includes a start time, duration and the number of units required. A scheduled resource class is provided with an availability and an available method. The availability method creates a set of segments for a list of reservations and iterates each segment to determine whether there are enough resources for the required units. The availability method then combines all adjacent reservations and removes reservations that are too short for the duration. The available method provides a way for user to determine if resources are available at and for a given time. A composite resource class is also provided for more than one scheduled resource with an availability and available method.
