Embodiments of the invention include a method, apparatus and system for providing a Serial Attached SCSI (SAS) domain management application using a domain overlay architecture. The method includes comparing user constructs or data sets defining an existing domain overlay with device data that identifies various network devices in at least one SAS domain, and binding the existing domain overlay to an SAS domain if the existing domain overlay and the SAS domain are uniquely associated with one another. The method also includes creating a new domain overlay that is uniquely associated with an SAS domain for any SAS domain that is not bound to an existing domain overlay. A domain overlay and an SAS domain are not uniquely associated with one another unless the domain overlay references only network devices within the SAS domain and the network devices within the SAS domain are referenced only by the domain overlay.
