摘 要

网络存储是近年来被广泛应用实用技术。按照存储资源的分布形式,网络存储可分为集中存储和分散存储两种模式。分散存储对网络性能、存储设备没有特殊要求,资源可广泛分布在多个位置,有利于大范围的数据共享。但是,在分散存储系统中,由于各个资源相互独立,资源和用户的管理难度大,用户对资源的访问十分不便,共享信息往往得不到充分利用。

针对以上问题,本文提出通过建立一个用户认证和管理系统UAMS,以虚拟账号方式管理用户,按照“资源分散存储、统一分配、用户集中管理”的模式整合分散存储资源。UAMS的核心是资源数据库和用户数据库,它们分别记录资源信息、用户信息以及资源分配情况。UAMS收集、记录各存储系统的资源属性信息和真实账号信息,将资源与虚拟账号关联,并把虚拟账号分配给用户。用户不必了解资源的具体情况,只需提交虚拟账号,通过身份认证后在UAMS的引导下就能访问所有资源。

在这种模式中,UAMS以中介的身份将用户和资源隔离,既能实现单点登录,又避免了各存储系统重复管理用户。统一身份认证还能提高整个存储系统的安全性。按照上述设计思路开发的UAMS存储管理系统已经应用在我校的某实验室中,该系统将分布在三个校区的多个存储资源整合,实现了分散存储系统的集中用户管理。

ABSTRACT

Network storage has been a widespread applied technology in recent years. According to the distribution form of stored resources, network storage can be classified into 2 modes: centralized storage and dispersive storage. Since dispersive storage requires no special network property and network devices, resources can be widely dispersed in any position, which is conducive to data sharing in a wide range. On the other hand, individual resource is independent of each other, which brings about difficulty of managing resources and users, inconvenience for users to access resources, and reduction of availability of shared information.

Considering the above-mentioned, the thesis proposes integrating disperse storage resources based on the mode of “disperse storage, unified allocation and centralized user management” through establishing an UAMS (User Authentication and Management System) and managing uses with virtual account. The core of UAMS is resource database and user database. They record resource information, user information and status of resource allocation. UAMS collects and records information of resource property and authentic account, associate resources with virtual accounts, and allocate virtual accounts to users. Unnecessary to understand the detailed information of resources, users can access all resources after applying for a virtual account and getting the identity authentication.

In this mode, UAMS acts as intermediate to separate users from resources. This provides convenience to users for accessing many dispersive resources and avoids repetitive management of users in each storage system. Moreover, unified identity authentication can improve the security of whole storage system. UAMS applied to a lab in Chongqing University have integrated multi-dispersive resources in three campuses and made centralized user management of dispersive storage systems.
