Are they Gigabit ethernet cards, or are they 2 gigabit ethernet cards, which can only talk to other Myrinet cards, like ARCNet is not the same thing as ethernet? Are the FDX through a Cisco or Extreme Networks Gigabit switch, getting 2Gbit, and you are just defining 2G as total over the wire transfer rate in *both* directions, requiring that data go both ways (i.e. 2G is an aggregate number, but it's still standards compliant Gigabit)??? -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
