Shirley> Have we ever seen silent data corruption in CHECKSUM_HW? Well, a quick web search finds stuff like http://my.adsm.org/modules.php?op=modload&name=phpBB_14&file=index&action=viewtopic&topic=2362&0
But what I was really talking about was the risk of sending IP packets without a checksum. It may be fine within the IB fabric, because the ICRC protects traffic end-to-end. But if you have a gateway/router between the IPoIB-connected-mode fabric and some other IP network, then that router would have to generate the TCP checksums, which means that router potentially becomes a source of silent corruption. There are interesting surveys such as http://portal.acm.org/citation.cfm?id=347561 about this. - R. _______________________________________________ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
