    Abstract: A technique for processing a lock request is provided. A first lock server is a takeover lock server of a second lock server. The first lock server enters a silent state after learning that a fault occurs in the second lock server, where a silent range is a resource for which the second lock server has assigned permission. The first lock server receives an acquire lock request that is originally sent to the second lock server, and the first lock server assigns lock permission for a corresponding resource according to the acquire lock request if the second lock server has not assigned resource for the resource. By means of this solution, an impact range of a fault occurring in a lock server can be reduced, and stability of a lock management system is improved.

    Abstract: A method for processing a fault of a lock server in a distributed system is disclosed, where the distributed system includes m lock servers, which locally store same lock server takeover relationship information. Lock servers in the distributed system that are not faulty receive a notification message, which carries information about a fault of a first lock server; after receiving the notification message, a second lock server determines that it is a takeover lock server of the first lock server according to the lock server takeover relationship information, and the takeover lock server enters a silent state; after receiving the notification message, a third lock server in the distributed system determines that it is not the takeover lock server of the first lock server according to the lock server takeover relationship information. After receiving a locking request, the third lock server allocates lock permission information according to the locking request.

    Abstract: Embodiments of this application provide a storage system. The storage system includes a first controller and a second controller, and the two controllers communicate with a memory by sharing a same interface card. The shared interface card stores data from the first controller in a cache of the shared interface card, and asynchronously persists data in the cache of the shared interface card to the memory. After the first controller is faulty, the data that is from the first controller and that is stored by the shared interface device may be read by an interface device from a cache (or a memory) of the interface device, and provided to the second controller.

    Abstract: A garbage collection technology for a storage medium that includes a plurality of blocks, where each storage unit has a collection parameter related to data in one of the blocks, and where each block includes a plurality of pages. A group of blocks is selected from the plurality of blocks based on the collection parameter. A difference between values of collection parameters of any two blocks in the group of blocks is not greater than a preset value. Data in a first valid page and a second valid page in the group of blocks is replicated to a same destination block, to facilitate garbage collection.
