Abstract
A method and apparatus are provided for implementing connection management in SAS expander devices. SAS expanders are commonly used within a SAS network topology to allow multiple disk drives to connect to multiple host devices. The method and apparatus provides arbitration of connection requests to be setup or removed among multiple end devices and expander devices so as to increase system performance and reduce hardware cost in a standard compliant manner.
