1. A method for managing a plurality of SAS domains each including at least one network device, wherein the at least one network device includes device data for identifying the network device, the method comprising the steps of: comparing device data within at least one data set that defines an existing domain overlay with device data that identifies the network devices in at least one SAS domain; binding the existing domain overlay to an SAS domain if the existing domain overlay and the SAS domain are uniquely associated with one another; and creating, for any SAS domain that is not bound to an existing domain overlay, a new domain overlay that is uniquely associated with the SAS domain that is not bound to an existing domain overlay.
