I was under the impression that if both devices are set up the same, and
both given the same metric values in ifconfig and route, that the
networking code would use both devices equally. However, I can't quickly
find where I read this...
OTOH, I've been thinking of doing this for a pair of machines that we have.
One is a web/ftp server, the other is the user machine. They share the same
disks for the web pages, via NFS. I've been thinking of just getting 2
100-BT cards and connecting them through a crossover cable. That provides
more than enough bandwidth than the striped (via MD) drives can fill.
