Method and device used for transmitting data processing request

Abstract

The embodiment of the invention provides a method and a device used for transmitting a data processing request. The method is applied to a storage system and is characterized in that the storage system comprises a first storage node and a second storage node, a storage device in the first storage node is connected with a host through a processor and a first network card of the first storage node,and the storage device in the first storage node is connected with a storage device of the second storage node through a second network card; the first storage node receives a data processing requestof accessing the storage device of the second storage node; the data processing request carries a target storage address of to-be-processed data; the first storage node determines the second storage node based on the target storage address of the to-be-processed data; the first storage node sends the data processing request to the second storage node through the second network card; and the data processing request indicates the second storage node to process the to-be-processed data. The method and the device used for transmitting the data processing request are conducive to increasing the success rate of accessing the target storage address in the second storage node.

Description

technical field [0001] The present application relates to the field of communications, and more particularly, to methods and apparatus for transmitting data processing requests. Background technique [0002] With the gradual increase of data scale, people's demand for storage devices is increasing. In order to meet people's needs for storage devices, network storage has become a common data storage method in current storage systems. A special dedicated data storage system is defined in the network storage technology, in which the cross-platform file sharing function can be realized. Specifically, network storage forms include direct attached storage (Direct Attached Storage, DAS), network attached storage (Network Attached Storage, NAS), and storage area network (Storage Area Network, SAN). [0003] The above-mentioned storage system based on network storage technology may include multiple storage nodes, and the multiple storage nodes may be connected to the host through t...

Problems solved by technology

[0004] However, if the storage device of the second storage node can only be accessed through the access path formed by the CPU of the second storage node and the first network card in the second storage node, when the CPU of the second storage node cannot process the data access request in time , the host cannot access the second storage node in time, or when the above-mentioned access channel of the second storage node fails, the host cannot access the storage device of the second storage node
