两个基本问题:
1) cvm集群和ESXI数据是否可以使用相同的10g交换机而不影响性能?
(我只有一对10g开关，NX1065有一个双端口卡。我们知道cvm集群必须使用10g的网络，但是ESXI数据网络我也想使用10g的网络。)
2)一般ESXI mgmt(通常是用于NFS访问的vmkernel端口)和cvm集群在同一个10g链路上(也可以是cvm prism mgmt)，如果用户想要为ESXI mgmt有一个单独的上行链路或子网，是否可以?我担心性能问题。
提前感谢!

\n\nThe only time, that I know, of that we have ran into any sort of network performance problem was when those ports were connected to really low end, terrible switches, like Cisco's FEX's (which are NOT a switch, just a density increasing line card).

\nThink about it, even in a three node cluster, you have 2x10x3 gbps of bandwidth, so 60gbps of bandwidth. Thats a TON, and you'd likely be limited by the uplinks FROM the 10G switch to the rest of the world (router, firewall, load balancer, all probably less than 60gbps of bandwidth)
\n
\nNow, expand that example out. In a 20 node cluster, thats 2x10x20 gbps of bandwidth, 400 gbps of bandwidth in total.
\n
\nCombined with the practice of data locality, where we are keeping almost all reads, and half of the writes OFF the network, that turns into us being VERY efficient on the bandwidth that is available.
\n
\nBandwidth is rarely, if ever, a problem in our architecture.","className":"post__content__best_answer"}">
