  • Methods and structure for a SAS/SATA converter
    Patent number: 7689744
    Abstract: Methods and structure for enabling transparent coordination between multiple host systems sharing access to a common SATA storage device to improve bandwidth utilization therebetween in a manner transparent to each of the multiple host systems. The SAS protocol may be utilized by each of the host systems coupled to an SAS/SATA Converter. The storage device coupled to an output path of the SAS/SATA Converter is selectively coupled to one of the multiple host systems each coupled to an input signal path of the SAS/SATA Converter to the shared SATA storage device. Protocol conversion within the SAS/SATA Converter may convert between host SAS protocol exchanges and SATA protocol exchanges of the storage device. Other features within the SAS/SATA Converter may provide queuing or buffering of SAS protocol exchanges from a host system presently non-selected for coupling to the shared SATA storage device.
