Abstract: The application provides a route synchronization method and an apparatus. The method includes: receiving, by a first FEF, an entire network address request message sent by a second FEF, where the entire network address request message includes an MAC address and an FC network segment of the second FEF; parsing, by the first FEF, the entire network address request message, acquiring the MAC address and the FC network segment of the second FEF, and storing the MAC address and the FC network segment of the second FEF in a routing table of the first FEF; and sending, by the first FEF, a response message to the second FEF, where the response message includes a MAC address and an FC network segment of the first FEF. Thus, distributed routing of an FCoE network is implemented, and scalability of the FCoE network is improved.

Abstract: A garbage data scrubbing method includes obtaining an input/output (IO) busy/idle status of a terminal at a current moment, where the IO busy/idle status includes a busy state and an idle state. When the IO busy/idle status of the terminal at the current moment is the idle state, a discard message is delivered to a storage device, where the discard message includes an initial address and a size of to-be-scrubbed physical space in the storage device, and where the discard message is used to unbind a mapping relationship between a physical address of the to-be-scrubbed physical space and a corresponding logical address.

Abstract: A method for executing a hard disk operation command, a hard disk, and a storage medium. After an operation command is received, a target LUN in an idle state is determined; a target physical block that is to be accessed when the operation command is executed is determined from the target LUN; the operation command is stored in a processing waiting queue corresponding to a flash memory chip to which the target physical block belongs; and a working state of the target LUN is changed to a non-idle state when a quantity of operation commands that wait to be processed in a processing waiting queue respectively corresponding to each flash memory chip in the target LUN is greater than a preset threshold.
