服务器是构建数据中心的基础设施,与计算机历史上存储与计算分离类似,PCI Express等互连技术的出现使下一代数据中心I/O走出机箱,构建外设网络成为可能。而如何对I/O资源进行高效地管理,虚拟化技术的提出很好地解决了这个问题。通过讨论由PCI-SIG组织提出的MR-IOV(多根I/O虚拟化)技术以及MR-IOV如何应用于数据中心的互连体系和I/O设备的共享,勾画出MR-IOV在刀片服务器中的应用前景,同时分析了MR-IOV存在的问题和当前研究现状,为下一代数据中心交换结构的设计提供一定的参考。

Server is the infrastructure to construct a data center. Similar to the breakaway between storage and computing in computer his-tory,the emergence of interconnection technology such as PCI Express makes the possibility of I/O to go out of chassis to construct pe-ripheral network in a data center. Meanwhile,how to manage the I/O recourses efficiently is a big problem faced now;the proposed virtu-alization technology has the ability to solve the problem. By discussing MR-IOV ( Multi-Root I/O Virtualization) technology and how to deploy MR-IOV to a data center interconnection and I/O devices sharing,outline the application prospect in blade servers. Additional-ly,analyze existent problems and research status of MR-IOV,supplying some references for the design of switching fabric of the next generation data center.
