Abstract

The invention relates to a data access method which comprises the steps that one-to-one-corresponding mapping relation of data receiving host identifiers and route configuration information identifiers is established and stored; one-to-one-corresponding mapping relation of the route configuration information identifiers and command word configuration identifier combinations is established and stored, and the command word configuration identifier combinations comprise a plurality of command word configuration identifiers which are separated from each other; one-to-one-corresponding mapping relation of the command word configuration identifiers and command word and sending host identifier combinations is established and stored, and the sending host identifier combinations comprise a plurality of sending host identifiers which are separated from each other; and according to the mapping relation, data access operation is completed. According to the data access method, rapid expanding of occupied storage space of route table information can be avoided, and in addition, the invention provides a data access device.

Description

technical field [0001] The invention relates to data storage technology, in particular to a data access method and a storage device. Background technique [0002] In the data storage system of the prior art, the data interaction between the data sending host and the data receiving host is realized through the data interaction server, and the data interaction server includes the receiving host and the sending host, and the sending host in the data interaction server is The data from the internal receiving host is returned to the data receiving host according to the request of the data receiving host. The routing table is the basis for the correct transmission of data. [0003] The main elements in the existing routing table between the internal sending host and the data receiving host include the identifier (RecvAgentID) of the data receiving host, the command word (CMD), and the ID of the internal sending host (SendD). For a given identifier and command word of a data rece...
