Abstract: Example methods and apparatus for data access are described. In one example, a memory expansion card receives a first data access request generated by a computing device based on an internal bus protocol. Then, the memory expansion card performs protocol conversion on the first data access request to obtain a second data access request in an external bus protocol format, where the external bus protocol includes a bus protocol for accessing external memory space of the computing device. Further, the memory expansion card accesses the external memory space based on the second data access request. The memory expansion card shields a difference between the bus protocols, and provides internal memory space for the computing device.

Abstract: A client device sends a first packet to a first storage device, to request that target data can be written into the first storage device, where the first packet includes a logical address into which the target data needs to be written. A front-end network adapter of the first storage device has a capability of parsing the first packet, and can process the first packet; writes the target data into the first storage device based on an indication of the first packet; and generates metadata, and records a correspondence between the logical address of the target data and the metadata, where the metadata can indicate a physical address at which the target data is stored in the first storage device.

Abstract: Example methods and network devices for order-preserving execution of a write request are disclosed. One example method is performed by a network device of a storage node. The example method includes receiving an order-preserving confirmation request, where the order-preserving confirmation request carries a first write address assigned for a first write request. It is confirmed that execution of a second write request for which a second write address has been assigned is not completed, where the second write address precedes the first write address. Sending feedback information for the order-preserving confirmation request is delayed.
