vsphere 处理NUMA

vsphere 4.1 之前: cpu调度会将一个VM的分配给一个home node,整个vm被看做一个NUMA client. 如果VM的vCPU数量超过一个NUMA node的可用数量,则不被看做一个NUMA client,vCPU平均分配到每个Node上. NUMA优化就没有了,因为无法整合到一个Node里头.而且会有远程访问内存的性能问题. 4.1引入了wide VM. 会划分更小的NUMA client. 内存访问性能提升25%到50% 工作负载的再平衡. 使用"relaxed co-…

Summarizing NUMA Scheduling两篇文章，解释得不错

http://vxpertise.net/2012/06/summarizing-numa-scheduling/ Sitting on my sofa this morning watching Scrubs, I was thinking about the NUMA related considerations in vSphere – yes, I am a nerd. I read about this for the first time back in the days of vS…

NUMA总结。

vsphere 5.1性能最佳实践http://www.vmware.com/pdf/Perf_Best_Practices_vSphere5.1.pdf vNUMA 要求:硬件版本8以上. 1.整个cluster中的所有主机具备匹配的NUMA构架的话,启用vNUMA会得到最大的性能提升. 当vm启动的时候它的vNUMA结构会根据底层的NUMA结构设定.而且初始化后不会变化,除非更改了vCPU的数量. 如果vm从一个主机vMotion到另外一个主机上,而该目的主机的NUMA结构和源主机不一致,则…
