| 摘 要： | 企业级用户在部署存储系统时往往需要能够支持多操作系统平台的存储虚拟化系统.给出了一种能够应用在Win-dow s操作系统的存储虚拟化客户端软件.该软件作为SAN环境下的存储虚拟化系统的一部分,在系统内核态提供虚拟存储的基本服务.此外,该软件运用按需分配技术提高了存储资源利用率;通过虚拟卷在线扩展技术可以在不中断服务的情况下完成大规模的数据迁移.实验结果表明,与传统虚拟卷相比,使用按需分配技术可以在不损失性能的前提下有效节约存储资源;通过在线扩展技术不仅在容量上和性能上得到有效扩展,还能够在数据迁移的同时始终保持虚拟存储服务的持续性.

| Abstract: | The enterprise-level customers demand certain virtualization storage products support multi-platform OS on the storage system deploying.This article proposes a storage virtualization client software running on Windows OS.As a part of the system of storage virtualization base on the SAN environment,the basic virtual storage can be served in the kernel mode of the Windows system.Moreover,this software utilizes Thin-Provision function to improve the storage resources utilization;Online-Extension function can complete large-scale date migration under the condition of online-service.The results show that,these functions can economize storage resources effectively without performance losses,and keep virtual storage service persistently during the data migration. |
