Lustre discuss - Aug 2009 - routing between infiniband and TCP networks

I have a small Lustre setup consisting of 3xOSS and 1xMDS/MGS connected via
Infiniband. How do you configure a LNET router to route between the IB and TCP
networks so a non-IB client can connect and use Lustre?

 

Our IB network is 192.168.200. and our TCP network is 192.168.10.

 

Thanks,

If your OSS/MDS nodes have an extra GigE interface that can route to  
the clients you want to attach via tcp, just set it up as a second  
interface (ie: each MDS/OSS has both o2ib0 and tcp0).  Works quite  
nicely, setup only requires some minor edits to modprobe.conf and  
doesn''t require wasting a node on routing.
