Abstract
A link negotiation method for enabling communication between first and second Serial Attached Small Computer Interface (SAS) storage devices operably coupled by an optical cable. The method includes continuously transmitting a non-SAS data pattern between the first and second SAS storage devices. In response to successful exchange of the non-SAS data between the first and second SAS storage devices, a SAS data pattern is continuously transmitted between the first and second SAS storage devices. In response to successful exchange of the SAS data pattern between the first and second SAS storage devices, an initial frame is continuously transmitted between the first and second SAS storage devices. Communication between the first and second SAS storage devices is enabled in response successful communication of the initial frame between the first and second SAS storage devices.
