如何提高VIF带宽利用率?

存储型号为FAS2240-4,用4个板载千兆以太口绑定VIF,LACP模式。

现用户前端主机配有万兆网卡,使用iscsi方式挂载存储空间。

由于IP Based Load balance算法,一台主机的读写数据只能走在VIF中的一条链路上,实际测试速度为70M/s,没法用足4个网口的带宽。

 

在此想问问各位有什么高招能够让一台主机跑满整个VIF的带宽呢?

 

不胜感激~

    It actually depends on the OS, some OSes will use a single TCP/IP socket to connect to the filer, which makes only one link usable.

    Some other OSes will use multiple connections, in that case you give a chance to LACP to balance the traffic across multiple links.

     

    For example, when creating the vif "-b port" lets you balance when the port used is different, even if source and dest IP are the same.

     

    You would have to consult the documentation of your OS to see how to use multiple connections for a single mount.
