The Intel NICs that I mentioned, 82576 and 82571EB, are both in use in
DRBD replication links with an MTU of 9000. We usually configure each such
link as a point-to-point bonding pair (balance-rr), and get 1.95 Gb/s
throughput with iperf, and about 165 MB/sec with drbd (but of course the
latter is disk dependent). CentOS 5.5, x86_64, Dell PE2900 servers. Solid.
