Abstract: Techniques are described for providing an automatic transfer switch (ATS), such as in a data center, to switch between a primary power system and a reserve power system based on a priority of the computing systems to which the ATS is supplying power. The ATS obtains the priority from a centralized database and obtains an existing load on the reserve power system. If the existing load is too high and the priority of the computing systems coupled to the ATS is too low, then the ATS may not switch to utilizing the reserve power system upon a failure in the primary power system.
