- An OSS really can't be a router, an OSS is an endpoint. Topologically, it shouldn't work, you should re-think network layout. - routing does place a load on the system, nodes doing routing should be dedicated to routing. - Load depends on traffic, basically you would have two hardware network interfaces, and ideally would be sending max traffic through both. Impact would depend on hardware types, etc.
WIth ~400 nodes, you would want a 'pool' of routers, size of pool would depend on your usage. cliffw On Tue, Mar 13, 2012 at 11:25 AM, Hayes, Bob <bob.ha...@intel.com> wrote: > 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?**** > > ** ** > > *Bob Hayes* > > HPC Sys.
