Is an SM running in the IB subnet ? > 2) I use IPoIB with Ethernet IB bridge (gateway). But I found about it only > few phrases on openfabrics site.

I think there are a few general approaches for IP connectivity between IB and ethernet: 1. Gateways (Voltaire has one, QLogic may (I forget)) 2. VNIC approaches (QLogic, Xsigo, maybe others) 3. Use linux box as IP router with ethernet and IPoIB interfaces What's best depends on your specific requirements. -- Hal > -- > Best regards, > Titov Alexander > _______________________________________________ > general mailing list > general@lists.openfabrics.org > http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general > > To unsubscribe, please visit > http://openib.org/mailman/listinfo/openib-general > _______________________________________________ general mailing list general@lists.openfabrics.org http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
