Abstract: A method and apparatus for determining a port rate determines a channel transmission rate of an SAS port including N physical channels. The method includes: determining M different negotiated rates of the N physical channels; separately determining M total port bandwidths corresponding to the M different negotiated rates; and determining a negotiated rate corresponding to a largest total port bandwidth in the M total port bandwidths as a channel transmission rate of the port. A lowest negotiated rate is no longer used as the channel transmission rate of the port, but the negotiated rate corresponding to the largest total port bandwidth is determined as the channel transmission rate of the port.
