Abstract: A memory access method includes: receiving, by the switch, a data packet; matching a flow table on the data packet, where the flow table includes at least one flow entry, where the flow entry includes a matching field and an action field, and the at least one flow entry includes a first flow entry, where a matching field of the first flow entry is used to match source node information, destination node information, and a protocol type in the data packet, and an action field of the first flow entry is used to indicate an operation command for a storage device embedded in the switch; and when the data packet successfully matches the first flow entry, performing an operation on the storage device according to the operation command in the action field of the successfully matched first flow entry.

Abstract: Embodiments of the present invention provide a method, an apparatus, and a system for reading and writing data, which relate to the computer field, can resolve a problem in the prior art that different algorithms need to be configured for write operations on storage devices of different optimization granularities. The method includes: acquiring first data to be written into a storage device and an address for the first data; acquiring, second data from the address of the storage device; acquiring configuration information; generating, according to the configuration information, a candidate data set; comparing data in the candidate data set with the second data, so as to acquire third data that is in the candidate data set and meets a preset rule; and writing the third data into the storage device according to the address.
