Embodiments of the present invention provide for creating and using persistent connections in SAS networks. A persistent connection may be a connection that persists for longer than the usual SAS connection. More specifically, it is a connection that is not subject to periodic tear downs by SAS devices according to existing SAS protocols (such as, by using CLOSE or BREAK primitives). Instead, persistent connections may be removable bra link reset Persistent connections may be used in situations in which the overhead associated with the usual tear down and re-establishment of connections in a SAS network may be considered too high in comparison with its intended benefits. Persistent connections way also be used to provide virtual direct attachment between two different SAS connected devices or between a SAS connected device and an expander. |
