Abstract:
1. A method operable in a Fast Context Switch (FCS) enhanced Serial Attached SCSI (SAS) expander, the method comprising: establishing a first connection between an initiator device and a first Serial Advanced Technology Attachment (SATA) target device directly coupled with the expander; receiving a DONE primitive from the initiator device before the first connection is closed; transmitting a DONE primitive to the initiator device in response to receipt of the DONE primitive; receiving a Switch Address Frame (SAF) from the initiator device over the first connection; and establishing a second connection between the initiator device and a second target device directly coupled with the expander without receiving a CLOSE primitive from the initiator device for the first connection, wherein establishing the second connection is performed in response to receiving the SAF and without closing the first connection.
