Abstract
Methods and structures for assuring proper sequencing of processing of SAS frames received over multiple physical ports of a SAS wide port. A frame scheduler element is communicatively coupled with a SAS transport layer and with a corresponding plurality of link layers operable as a SAS wide port. The frame scheduler receives a request from the transport layer to locate or select a next received frame for further processing. The frame scheduler interacts with the plurality of link layer processing elements having received frames stored within to locate the link layer that has the requested next frame. The frame scheduler then coordinates operation of that link layer and the transport layer to effectuate the transfer of the required next frame.
