一种基于Windows操作系统的存储虚拟化在线扩展技术

摘要

Cloud computing, large data and other traditional applications in the storage system is often the form of virtualization to run on the open source Linux platform, as storage virtualization technology continues to mature and diversify, users also need Windows-based storage virtualization services.Aiming at these requirements, this paper presents a software based on Windows operating system platform to provide storage virtualized service, which can be used to create virtual local disk in Windows operating system.The data in the disk is evenly distributed across the underlying physical disks in striped form.The software is based on the mass storage network system TH-MSNS, in the storage area network SAN environment to provide users with virtual disk services and support online capacity expansion Mter testing,it proves that the striped volume can guarantee uninterrupted foreground application and carry out large-scale data migration quickly and accurately.When users need to expand the capacity of the virtual disk, the use of this technology can guarantee the reliability of the virtual disk can also improve the read and write performance after expansion.%云计算、大数据等传统应用系统中的存储系统往往以虚拟化的形式运行在开源的Linux平台上,随着存储虚拟化技术不断成熟并向多元化发展,用户同样需要基于Windows平台的存储虚拟化服务.针对这些需求,提出一种基于Windows操作系统平台提供存储虚拟化服务的软件,可实现在Windows操作系统中创建虚拟的本地磁盘供用户使用,磁盘中的数据以条带化的形式平均分布在底层各个物理磁盘上.该软件基于海量存储网络系统TH-MSNS,在存储区域网SAN环境中为用户提供虚拟磁盘服务并支持在线容量扩展.通过测试后证明,条带卷在进行在线扩展时可以保证前台应用不中断,并且能够快速准确地完成大规模的数据迁移.当用户需要扩充虚拟磁盘的容量时,使用此项技术既可保证虚拟磁盘的可靠性又可提高扩容之后的读写性能.
