Abstract
Methods and associated structure to assure correct order in delivery of SATA frames over a SAS wide port. In one aspect hereof, new connection requests from a SATA device are rejected until prior frames residing in receive buffers of the SAS/SATA controller are properly processed. In another aspect, when a device is already connected to the controller, the SAS/SATA controller may prevent return of a receiver ready primitive in response to a transmitter ready primitive until previously received frames are removed from the receive buffers.
