Problems solved by technology

There are two main solutions for traditional virtualization technology. The first is to implement agent software on each host. The common one includes LVM in Linux system. This method is not suitable for multi-machine environment, nor is it suitable for different operating system; the second solution is implemented on the storage device side. Array devices of many manufacturers also provide virtualization functions, but this method is generally oriented to specific devices and cannot manage multiple types of devices
Both of these solutions cannot meet the needs of massive heterogeneous storage network environments

Embodiment Construction

[0090] 1. Configuration and organization of hardware devices

[0091] We named this self-developed virtualization system for mass storage networks AXUM, and the processors running the AXUM system in the network are called VIC nodes. The organizational structure of the storage network as the AXUM operating environment is as follows: image 3 shown. All hardware devices, including front-end hosts, VIC nodes, common I / O processing nodes and fiber optic disk devices, are connected to one or more fiber optic switches through fiber optic cables. There are one or more front-end hosts installed with fiber channel cards (FC-HBA) in initiator mode, which are used to query and access storage devices available in the fiber optic network; one of the front-end hosts is used as a management host and needs to be installed with a management interface . Ordinary I / O processing nodes are equipped with fiber channel cards in target mode, and IDE or SCSI type disks or disk arrays are connected ...

Abstract

A management method of large scale storage resource includes maintaining a set of storage resouce disposal information by node machine of special processor to manage different storage device resource in storage network so as to provide virtual storage service for front end host by carrying out process of command analysis with interface middle layer of small computer interface. The node machine with information list and software target machine can convert virtual access to be access of physical device.

Description

technical field [0001] A network-based mass storage resource management method in a SAN environment belongs to the field of storage area networks, and particularly relates to the field of virtualization technology therein. Background technique [0002] With the rapid development of information technology, the amount of data that people have to deal with continues to increase, resulting in a huge demand for storage system capacity and performance, and making traditional storage methods unable to meet the needs of users. Generally, each host has its own storage device, which makes information scattered on each host, forming an information island, which is not conducive to information integration. And network storage can provide shared information access service, and has super large capacity and excellent performance, so it becomes the development trend of storage system. A storage area network (Storage Area Network, SAN) is a specialized storage network, which can connect var...
