Abstract: An input output (I/O) request processing method is applied to a storage system and includes: receiving an I/O request, where the I/O request carries a size and a to-be-accessed address of the I/O request; determining a type of a to-be-accessed storage device according to the to-be-accessed address; selecting, according to the size of the I/O and the determined device type, from M (physical layers) PHYs configured for the determined device type, a PHY for transmitting the I/O, where the PHYs configured for the storage device of this type are determined according to a total quantity of PHYs in the storage system, a percentage of a quantity of devices of this type in the storage system, and a size of an I/O received by the storage device of this type within a previous access period; and sending the I/O to the storage device by using the selected PHY.

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.
