Abstract :
Virtualization is vital important in server consolidation. Using virtualization technology, a single physical machine can provide multiple isolated virtual machine for users, which will improve the overall system resources usage. However, In virtualization environment, Non-Uniform Memory Access Architecture (NUMA) problem is also a very important parameter that affects server´s performance. To solve NUMA problem, many solutions have been proposed to reduce its performance impact on virtual machines and improve the overall system performance. Hardware Single Root I/O Virtualization (SR-IOV) is a solution for high performance network processing, but when SR-IOV technology is running on a NUMA platform, it also generates the traditional problem about NUMA.
