Abstract

The invention provides a distributed block storage data access method and system based on an iSCSI (Internet Small Computer System Interface) protocol. The method comprises the steps of constructing a multi-resource management system based on a virtual IP (Internet Protocol) mechanism, wherein the multi-resource management system comprises an initiator layer, an iSCSI protocol layer and a storage layer; and allocating virtual IP resources to each cluster node based on dynamic feedback, so that each cluster node balances the load. The distributed block storage data access method and system based on an iSCSI protocol can meet iSCSI multi-path access of distributed cluster block storage, provide a high available and high concurrent access gateway, reduce authority conflicts of concurrent access of the distributed block storage, avoid the performance bottleneck of resource balance, and provide a guarantee for security and reliability of data access.

Description

technical field [0001] The invention relates to the technical field of cloud storage, in particular to an iSCSI protocol-based distributed block storage data access method and system. Background technique [0002] Traditional network storage systems use centralized storage servers to store all data. The storage server has become the bottleneck of system performance and the focus of reliability and security, which cannot meet the needs of large-scale storage applications. [0003] Distributed storage is to disperse and store data on multiple independent devices. It adopts a scalable system structure, uses multiple storage servers to share storage load, and uses location servers to locate and store information, which not only improves system reliability, availability and Access efficiency, but also easy to expand. [0004] In the prior art, a kernel state LIO access method is adopted for distributed block storage. However, the secondary development of this access method is ...
