I'm curious if anyone has any positive or negative experiences with the various 10Gbe NICs available, in an SL5 system? I've heard of instability when using the Intel NICs (this on a CentOS 5 system, but I assume similar behaviour to SL), good reports on the Myricom NICs, and another positive report on Chelsio from our supercomputing guys (though I believe they are running Suse).
