unraid全固态下内网传输速度过低问题

Featured Replies

主板上插了4个4tb的m.2,均是pci4.0满速。内网是万兆,七类网线,交换机tplink的st1008。无校验盘。eth0和eth2绑的bro,eth1开启了sr-iov,所有网口都接了st1008万兆交换机。

 

目前PC往unraid的写入速度只能达到70-90MB/s,这速度连千兆都跑不满,试过PC万兆网卡和2.5G网卡写入unraid,速度都是70-90没有任何区别。网卡是x540-t2开启了sr-iov,然后直通给了虚拟机,用windows虚拟机写入unraid硬盘的速度倒是可以1.6GB/s。

 

unraid的网络传输速度一直很让人吐槽,但是我查了很多遍自认为把影响速度的环节都避免了,实在是不清楚是什么原因导致的。

另外我还设置了文件不拆分,以排除传输时拆分文件cpu负载造成的影响,所有文件只存到指定单独的固态中。

unRAID 万兆网卡速度达不到,参考:Unraid 万兆网络实现注意事项

非常感谢,这篇文章非常有价值,我先按照上面要求每项都做一遍。

 

另外我今天确实发现,因为我主板上的2.5G网口(eth0)和pci的10G(eth2)网口都桥接在br0上,如果我两个网口都接万兆交换机,传输速度就只有90MB/s不到,但是我把2.5G网口接交换机的网线断开,交换机只接unraid的10G网口,再测内网传输速度就几百兆/s了。请问这是什么原因?
