Abstract

The invention discloses a method, a device, a system and a storage medium for storing data by an elastic block. The method comprises the following steps: a distributed file system Ceph is set as a system for storing data, and the communication protocol of the Ceph is an rbd protocol; a request for elastic block storage data with Ceph based on iSCSI protocol is received; upon request, the rbd protocol and the iSCSI protocol are converted; the elastic block stores data according to the converted same protocol. On the one hand, the embodiment of the invention can avoid the risk of logic error dueto the local hard disk mapped by ceph, effectively reduce the failure rate and improve the stability of the system; on the other hand, the embodiment of the invention can reduce the system performance consumption and the service response time delay by reducing one mapping.

Description

technical field [0001] The present invention relates to the field of storage technology, in particular to a method, device, system and storage medium for elastic block storage. Background technique [0002] With the rapid development of enterprise cloud computing platforms, there is an increasing demand for block storage to store various types of virtual machines and application data. Currently, the elastic block storage technology solution is an open source solution, which can provide users with high-speed block high-speed data storage services. Users can use block storage devices to write data or read data in the form of volumes on virtual machines or physical machines. In the current open source solution, the Ceph (distributed file system) volume is first mapped to a local hard disk, and then the local hard disk (mapped from Ceph) is mapped to a small computer system interface (Internet Small Computer System Interface, iSCSI) service A logical unit number (Logical Unit ...
