摘要： Methods and structure for directly coupling SATA hosts (SATA initiators) with SATA target devices through a SAS fabric and an enhanced SAS expander supporting such direct couplings. The enhanced SAS expander comprises SATA/STP connection logic to open a SAS (STP) connection between a directly attached SATA host and a SATA target device in response to receipt of an FIS from the host or target while no connection is presently open. The opened connection is closed after expiration of a predetermined timeout period of inactivity between the connected host and target. Thus, simpler, less costly SATA hosts and SATA target devices may be utilized while gaining the advantage of SAS architecture flexibility in configuration and scalability. SATA hosts may be coupled through the SAS fabric with a larger number of SATA target devices and multiple SATA hosts may be coupled with the SAS fabric.

摘要： Systems and methods provide zone management for devices in a Serial Attached Small Computer System Interface (SAS) topology. In one embodiment, a zone management device stores a zone map that identifies an initial zone of a device in the topology. The management device detects changes in the topology, and identifies a current zone of the device subsequent to the change in the topology. The management device compares the zone map for the device to the current zone to identify a change in the zone of the device, and generates a message for an expander in the topology based on the change in the zone. The management device then transmits the message to the expander to restore the zone of the device to the initial zone.
