The Research And Implementation Of Virtual Management Software In SAN Storage Management System

Storage Area Network is a new network storage structure. It is different from the traditional network for communication; it optimalizes the data transition from server to disk array or tape; it increases the highly reliability and security reading volume data by SCSI protocol; and it provides the share of big load storage device data. So it makes the method of connecting with host and storage device changing essentially.Virtual storage technology can make user conveniently duplicate and backup data, manage and store SAN storage resources, and utilize the storage space more fully and more high-efficiently. In this paper, we will analyze about the virtual storage technology, and introduce several realization method of SAN virtual storage technology, according to the virtual realization position in SAN. system structure. At last we will introduce the feature and the realization of the virtual storage technology based on the special-purpose Server in detail.This paper introduces a basic structure of SAN storage based on the discussion of the development of network storage, virtual storage technology, and the related technology. According to the design and realization of a virtual storage management system the writer involved in, the writer provities a basic structure realizing the software and describes the module of backup and recovery which he had studied mainly and discusses the kernel design of the detailed technology. The achievements are as follows:(1) The structure design and realization of a process communication model(2) The design and realization of a wait queue schedule model(3) The design and realization of a volume access restriction (4) The analysis and modification of volume searching method(5) The realization of Remote functionAt the last, the writer gives out some analysis of the SAN management software, not only lists the merits and demerits, but also puts forward some improvement images.
