The nodes are connected via a common switch, which supports large jumbo frames (10k) and jumbo frames are enabled. Each node's NIC is set to the same MTU=x number. No routers involved, and the NICs themselves also support 9kb JFs. -- Digimer E-Mail: digi...@alteeve.com AN!Whitepapers: http://alteeve.com Node Assassin: http://nodeassassin.org -- Linux-cluster mailing list Linux-cluster@redhat.com https://www.redhat.com/mailman/listinfo/linux-cluster
