摘要

服务器整合通过在具有虚拟化的单个平台上运行多个虚拟机,为现代多核处理器系统的并行性和利用率提供了有效的解决方案。然而,在现代大型高级服务器上,服务器整合解决方案的性能和可扩展性并没有得到很好的解决。在本文中,我们对运行SPECvirt_sc2010的Xen性能和可伸缩性特性进行了全面的研究,并确定由于不必要的频繁上下文切换,大量内存和缓存占用给系统性能和可伸缩性带来了额外的挑战。我们提出了两种优化方法(动态可分配微线程和上下文切换速率控制器)来提高性能。结果表明,通过降低总体CPI,提高了内存和缓存效率,从而使SPECvirt_sc2010中的服务器整合能力提高了15%。同时,我们的优化实现了高达50%的服务响应加速,极大地提高了Xen虚拟化解决方案的QoS。

Virtualization challenges: a view from server consolidation perspective
Server consolidation, by running multiple virtual machines on top of a single platform with virtualization, provides an efficient solu-tion to parallelism and utilization of modern multi-core processors system. However, the performance and scalability of server con-solidation solution on modern massive advanced server is not well addressed. In this paper, we conduct a comprehensive study of Xen per-formance and scalability characterization running SPECvirt_sc2010, and identify that large memory and cache footprint, due to the unnecessary high frequent context switch, introduce additional challenges to the system performance and scalability. We propose two optimizations (dynamically-allocable tasklets and context-switch rate controller) to improve the performance. The results show the improved memory and cache efficiency with a reduction of the overall CPI, resulting in an improvement of server consolidation capability by 15% in SPECvirt_sc2010. In the meantime, our optimization achieves an up to 50% acceleration of service response, which greatly improves the QoS of Xen virtualization solution.
