Abstract:
1. A method to set a communication speed in a serial attached small computer system interface (“SAS”) and serial-ATA (“SATA”) distance extender apparatus, comprising the steps of: supplying a SAS/SATA distance extender apparatus comprising a SAS/SATA interface 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 said SAS/SATA interface, said Fibre Channel interface, said memory, and said processor; detecting traffic received by said Fibre Channel interface; determining if said traffic comprises a SAS/SATA Open Address frame; operative if said traffic comprises a SAS/SATA Open Address frame, determining if said local communication speed matches a communication speed utilized by an interconnected remote SAS/SATA interface; operative if said local communication speed matches a remote communication speed utilized by an interconnected remote SAS/SATA interface, transmitting said traffic using said local SAS/SATA interface, wherein if a local Fibre Channel interface has received traffic, further comprising the steps of: removing Fibre Channel Start Of Frame delimiter and End Of Frame delimiter; removing a CRC portion of said traffic; and converting in said traffic D characters to corresponding K characters.
