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

[0077] Preferably, the application server first runs according to the steps of the read operation described in the first specific implementation of the present invention, and then when the read file is modified by the application server and then written back to the hard disk, then according to the first specific implementation of the present invention The steps of the writing operation are executed; at the same time, the IPSAN control server operates the mapping table between the logical LBA and the physical LBA: it records the new mapping relationship and deletes the old mapping record.

Abstract

The invention discloses a method for avoiding data read-write bottleneck under high concurrency. In an enterprise-level memory system constructed by a full internet small computer system interface (iSCSI) protocol, an internet protocol storage area network (IPSAN) control server divides a virtual memory space into a plurality of logical volumes and distributes the logical volumes to multiple application servers to use. Due to the fact that virtualized management exists, the IPSAN control server can enable one logical volume address to be mapped with physical addresses of multiple mono-block iSCSI hard disks and enables storage resources of the same hard disk to be distributed to the multiple application servers. Therefore, by formulating an operation method and processes for the IPSAN control server, the IPSAN control server can enable logical volume addresses corresponding to data blocks operated by the application servers to correspond to physical addresses of the hard disks, and serious impact on performance of the whole enterprise-level memory system caused by concentrated access on some hard disks when the hard disks encounter the read-write bottleneck is avoided.

Description

Technical field [0001] The invention relates to the field of data transmission and storage, in particular to a method for a full iSCSI protocol enterprise-level storage system constructed on the basis of an iSCSI hard disk to avoid a high concurrent data read and write bottleneck in a multi-application server access mode. 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, tape libraries). Through the role 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, and the transmission medium is an IP network (a network formed by connecting all computers using the IP protocol, that is, an interconnection network using the IP protocol), and its typical application is the iSCSI storage...
