Abstract

The invention discloses a storage path selection method and device. The method comprises: determining multiple storage paths between a sending end and a receiving end; sending a heartbeat data packet to the receiving end through each storage path; receiving a heartbeat acknowledgement data packet, which is returned to the sending end by the receiving end based on the heartbeat data packet; determining all reachable alternative storage paths of the storage paths according to the state of the heartbeat acknowledge data packet; calculating a path evaluation value of each alternative storage path; and determining selectable paths of the alternative storage paths according to the path evaluation values. According to the storage path selection method and device, a technical problem that the alternative storage paths cannot be accurately selected is solved.

Description

technical field [0001] The present invention relates to the field of data communication, in particular to a storage link selection method and device. Background technique [0002] In the prior art, in the process of connecting the server to the storage device, multiple storage links need to be established between the server and the storage device to provide network support for carrying stored data transmission. Based on the consideration of reliability redundancy and bandwidth improvement, the server Generally, multiple optical fiber cards are used to connect multiple optical fibers, and then multiple storage link connections are established. Furthermore, when a single storage link is used to transmit data, one of the storage links is selected as the main storage link for data transmission, and other candidate storage links are used as backup redundancy; when multiple storage links are used to transmit data at the same time, the data It can be transmitted on multiple storag...
