Abstract: An embodiment of the present invention includes a communication system configured to conform to SATA or SAS standards and causing communication between one or more hosts and a SATA device. The communication system includes a communication device adapted to generate debug information incorporated through one or more links using an analyzer to identify problems associated with the communication system.

Abstract: An embodiment of the present invention includes a communication system configured to conform to SATA and/or SAS standards and causing communication between one or more hosts and a SATA device. A multi-port bridge device is in communication with the one or more hosts through at least one link, the bridge device includes a power control block operative to control power to a SATA device through a power connection, wherein the power control block causes power to be provided to the SATA device even when the at least one link is operational.

Abstract: An embodiment of the present invention includes a communication system configured to conform to SAS standard and causing communication between one or more hosts and a SATA/SAS device. The communication system includes a multi-port bridge device including two or more SAS ports through which the bridge device communicates to hosts. The multi-port bridge device further includes a SATA port through which the bridge device communicates to a SATA device, each said SAS ports having associated therewith addresses for identifying the ports, the bridge device operative to generate addresses unique to each SAS port and operative to communicate the port addresses, through a SAS frame, wherein identification of SAS ports is achievable even when the SATA device is inoperational.
