摘要： A data transmission system includes a first data transmission device for receiving commands from a host; a second data transmission device for transmitting commands to a memory device; and a crossbar device for receiving commands from the first data transmission device over a first link and transmitting the commands to the second data transmission device over a second link. The crossbar device includes status logic to detect a command transmission error on the first link from the first data transmission device and transmits a retry command to prompt the first data transmission device to retry the transmission of the command over the first link. The second data transmission device reports a transmission error on the second link to the status logic of the crossbar device and the status logic of the crossbar device transmits the retry command to prompt the first data transmission device to retry the transmission of the command over the first link.

摘要： A data transfer retry method includes: A. receiving a particular atomic data transfer command from a director; B. processing identification information associated with the particular atomic data transfer command; C. comparing the identification information associated with the particular atomic data transfer command to identification information of a previous atomic data transfer command received from the director; D. determining that the particular atomic data transfer command is a retry command of the previous atomic data transfer command received from the director; E. determining a status of the execution of the previous atomic data transfer command received from the director; and F. processing the particular atomic data transfer command based on the status of the execution of the previous atomic data transfer command determined in Step E.
