Abstract

The invention discloses a communication method, device and equipment for a multi-control storage cluster and a computer readable storage medium, which are applied to any storage node in the multi-control storage cluster. Each storage node simultaneously has the functions of a sending end and a target end in an SCSI protocol. The method comprises: receiving an SCSI command, and acquiring an LUN IDcarried by the SCSI command; if the LUN ID is a preset specified ID, determining that the SCSI command is sent by a storage node in the multi-control storage cluster, and returning data required by the storage node corresponding to the SCSI command to the storage node sending the SCSI command; and if the LUN ID is the LUN ID of the client host side, determining that the SCSI command is sent by theclient host side, and returning data required by the client host side corresponding to the SCSI command to the client host side. Due to the fact that only data corresponding to the SCSI command needed by the sending end needs to be returned to the sending end, the communication efficiency is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of multi-control storage clusters, and more specifically, to a communication method, device, equipment and computer-readable storage medium for multi-control storage clusters. Background technique [0002] Before using SCSI (small computer system interface, small computer system interface) to communicate, it is necessary to establish an ITN (Initiator Target Nexus), which is the connection from SCSI Initiator to SCSI Target. Based on this connection, SCSI Initiator and SCSI Target have a one-way Specifically, the SCSI Initiator is used to send SCSI commands, and the SCSI Target is used to receive and process SCSI commands and return the execution status. However, SCSI needs a carrier for transmission, which leads to the emergence of SCSI-based transmission protocols such as FCP-SCSI and iSCSI. Among them, FCP-SCSI establishes an ITN through the FCP fiber channel protocol, and transmits the SCSI prot...
