Abstract: This application discloses a data writing method. A network controller performs erasure code encoding on original data, and writes a third quantity of target data blocks of a plurality of obtained target data blocks into a storage node. The network controller reads a first quantity of target data blocks of the third quantity of the target data blocks from the storage node, and decodes the read target data blocks. The plurality of target data blocks include a first quantity of original data blocks and a second quantity of check data blocks, two ends of a target data block include same version information, and the third quantity is greater than the first quantity.

Abstract: A write request processing method and a memory controller, where the method includes, determining a second write request set, by the memory controller, after determining that a quantity of write requests in a to-be-scheduled first write request set is less than a quantity of unoccupied storage units in a memory, where the write request in the first write request set is located before a first memory barrier, where a write request in the second write request set is a log write request, and where the write request in the second write request set is located behind the first memory barrier. The memory controller sends the write request in the first write request set and the write request in the second write request set in parallel to different unoccupied storage units in the memory.

Abstract: A read/write request processing method and server are provided. In this method, each terminal is grouped, and different service durations are assigned for all terminal groups, so that a server can process, within any service duration, only a read/write request sent by a terminal in a terminal group corresponding to the service duration. According to the application, a cache area of a network interface card of the server is enabled to store only limited quantities of queue pairs (QPs) and work queue elements (WQEs), thereby preventing uneven resource distribution in the cache area of the network interface card.
