Method for realizing block protocol interface based on cluster storage system

Abstract

The invention discloses a method for realizing a block protocol interface based on a cluster storage system, belonging to the field of computer and network information technology. A virtual block interface module is respectively arranged at every data node of the cluster storage system, so that the functions of virtual address mapping, writing distribution and the like can be realized, and a block device interface can be provided for upper layer SCSI Target program; the virtual block interface module comprises a block device export module, a virtual address mapping module, a writing distribution module and SCSI Target program; the block device export module is connected with a cluster storage volume of the cluster storage system, the virtual address mapping module and the writing distribution module are respectively connected with the block device export module, and the SCSI Target program is connected with the virtual address mapping module and the writing distribution module. Based on the high performance, expandability, availability and cost performance of the cluster storage system, the method realizes the block interface storage service, and meets the rapidly development demand of the current information processing and storage.

Description

technical field [0001] The invention relates to the field of computer and network information technology, in particular to a method for realizing a block protocol interface based on a cluster storage system. Background technique [0002] With the development of computer and network technology and the improvement of social informatization, many large-scale applications facing massive data have emerged one after another. The performance requirements of these applications for storage devices have gradually increased to the GB level, while traditional disk arrays generally only have one or With two controllers, the number of data interfaces is only 2-4. A single array has reached the limit of physical hardware and is expensive when meeting GB-level bandwidth requirements. However, the bandwidth requirements of some video and high-performance computing applications have already reached tens of GB. The use of ordinary single-controller and dual-controller arrays is no longer suita...

AI Technical Summary

Problems solved by technology

However, the currently applied storage cluster system only provides file interface services and cannot provide block interface services, which limits the expansion of such storage systems in the application fields of block interfaces such as databases.
