Thanks for sharing your experiences. So i must configure both nics as a team. I 
tried to avoid this, because of my bad experiences with teaming under windows 
and linux. All teaming configurations with different hardware at different 
customers 
show no throughput gain on the receive side. The load balancing(also 802.3ad) 
works only for send packets. This is useless for backup servers and storage 
nodes... Maybe the HP-UX IP stack can surprise me this time.

greetings
