Problems solved by technology

[0003] The purpose of the present invention is to provide a data transmission method for an enterprise-level storage system, which solves the problem that in an enterprise-level storage system built with a distributed full iSCSI protocol, when multiple application servers perform highly concurrent read and write operations on their assigned logical volumes, Due to centralized access to a certain physical hard disk, the performance of the entire storage system is severely degraded

specific Embodiment approach

[0076] Finally, as another specific embodiment of the present invention, when the application server needs to modify the file;

[0077] Preferably, firstly, the application server runs according to the steps of the read operation described in the first implementation of the present invention, and then when the read file is modified by the application server and written back to the hard disk, then follow the steps in the first implementation of the present invention. The steps of the write operation are executed; at the same time, the IPSAN control server operates on the logical LBA and physical LBA mapping table: it not only records the new mapping relationship, but deletes the old mapping record.

Abstract

The invention discloses a method for avoiding the bottleneck of data read and write under high concurrency; in the enterprise-level storage system constructed by the full iSCSI protocol, the IPSAN control server divides the virtual storage space into multiple logical volumes and distributes them to multiple applications Server use; due to the existence of virtualization management, the IPSAN control server can map a logical volume address with the physical addresses of multiple single iSCSI hard disks, so that the storage resources of the same hard disk will be allocated to multiple application servers use; therefore, by formulating an operation method and process for the IPSAN control server, it can correspond to the logical volume address corresponding to the data block to be operated by the application server and the physical address of the hard disk accessed by the non-hotspot, avoiding due to When centralized access occurs on a certain hard disk, and the hard disk reaches a read-write bottleneck, it will seriously affect the performance of the entire enterprise-level storage system.

Description

technical field [0001] The invention relates to the field of data transmission and storage, in particular to a method for avoiding high concurrent data read and write bottlenecks in a multi-application server access mode of a full iSCSI protocol enterprise-level storage system built on the basis of an iSCSI hard disk. Background technique [0002] SAN (storage area network) is an architecture in computer information processing technology, which connects application servers and remote computer storage devices (such as hard disk arrays and tape libraries). Through the functions of the protocol conversion program and the network driver, the application server recognizes these network storage devices as local storage devices. IPSAN is a SAN network using IP technology. The transmission medium is an IP network (a network formed by interconnecting all computers using the IP protocol, that is, an interconnection network using the IP protocol). Its typical application is the iSCSI s...
