As the packet rate is one limiting factor, this has been discussed before. With UD, the IB limit is 4K (-4 for CRC) but the device limit is 2K (-4), which is the default MTU for IPoIB. hence 2044 for normal IPoIB. This is one of the main reasons for IPoIB connected mode, which is not currently supported by OpenIB IPoIB. Given that there are now 2 ULPs which use the CM, this wouldn't be hard to support. (It's more a matter of someone having some time to do this). Note that IPoIB connected mode is currently an internet draft. -- Hal _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
