Abstract

The invention provides a distributed storage method and device, electronic equipment and a storage medium, which are used for solving the problem that a single point of failure greatly influences the stability of a distributed storage service. The method comprises the following steps: receiving an iSCSI data packet sent by a virtual machine; analyzing the iSCSI data packet into an SCSI command through an iSCSI target process of the visitor object, storing the SCSI command in an annular queue of the visitor object, and the SCSI command being a command for operating logic block equipment of a logic unit number corresponding to the virtual machine; reading and processing the SCSI command from the annular queue through a scheduler process of the visitor object to obtain an SCSI processing command; and sending the SCSI processing command to the distributed storage system, so that the distributed storage system returns an operation result corresponding to the SCSI processing command.

Description

technical field [0001] The present application relates to the technical fields of big data, cloud computing and distributed storage, and in particular, to a distributed storage method, device, electronic equipment and storage medium. Background technique [0002] Small Computer System Interface (SmallComputer System Interface, SCSI) is an independent processor standard for system-level interfaces between computers and peripheral devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). The SCSI standard defines commands, communication protocols, and electrical characteristics of entities. The largest part of the application is on storage devices (such as hard disks and tape drives). Except for SCSI, devices that can be connected include scanners and optical devices (such as CDs and DVDs). , printers, etc. [0003] Internet Small Computer System Interface (iSCSI), also known as Internet Protocol-Storage Area Network (Internet Protocol-Storage Area Networ...
