[Lustre-discuss] Seeking LNET router recomendations

[Hayes, Bob]

Are there any recommendations or guidelines for sizing a LNET routing facility.
~400 nodes, 8 OSS (dual socket E5 w/48GB RAM), 24 OST (10spindle RAID6 over SRP), 1 MGS/MDT
How much load does LNET routing put on a system?
If I make the 8 OSS systems do double duty as IB to IPoIB routers, will it have much impact on performance?
