ABSTRACT:
A method to set a communication speed in a Serial-Attached Small Computer System Interface (“SAS”)/Serial-ATA (“SATA”) distance extender apparatus comprising a plurality of supported communication speeds and a local communication speed, a fibre channel interface, a memory, a processor, and a communication bus interconnecting the SAS/SATA Interface, the Fibre Channel interface, the memory, and the processor. The method detects traffic received by the Fibre Channel interface, and determines if the traffic comprises a SAS/SATA Open Address frame. If the traffic comprises a SAS/SATA Open Address frame, the method then determines if the local communication speed matches a communication speed utilized by an interconnected remote SAS/SATA Interface. If the local communication speed matches a communication speed utilized by an interconnected remote SAS/SATA Interface, the method transmits the traffic using the local SAS/SATA Interface.
