Abstract: Multiple servers such as a main server as well as one or more corresponding sub-servers manage configuration information associated with a storage area network. A sub-server operates differently depending on whether the sub-server has been “integrated” with a main server in the storage area network. For example, in response to detecting a presence of a main server in the storage area network and that the corresponding sub-server has been integrated with the main server, a respective sub-server initiates execution of at least a portion of function calls associated with a respective service at the main server in lieu of executing the function calls locally at the respective sub-server. In the absence of the main server and/or integration, the sub-server operates independently and executes function calls locally rather than forward function calls associated with a respective service to the main server.
