分布式I／O资源虚拟化技术的研究

提出一种可有效整合和使用分布式I/O资源的新方案.该方案实现于操作系统和系统硬件之间,主要采用最新的硬件虚拟化技术,将分布于多主机的I/O资源进行虚拟化和整合,为上层客户操作系统构建一个全局虚拟I/O空间,实现客户操作系统对分布式I/O资源的全局管理和使用.该方案实现于系统软件层,性能较高、实现成本低,并且客户操作系统无需做任何修改.

Research on Virtualization Technology of Distributed I/O Resource

In this paper, a new solution is put forward for integration and utilization of the distributed I/O resources effectively. This solution is built between the operating system layer and the system hardware layer, mainly based on the latest hardware virtualization. It may virtualize and integrate the I/O resources distributed on multiple computer nodes, present a uniform virtual I/O space for the upper guest operating system, carry out the uniform management and utilization of distributed I/O resources for the guest operating system. This solution implements in the system software level, advanced in the performance and the implement cost. Additionally, the guest operating system dispenses with any modification.
