10-GigE for servers

As long as it's not a single connection that you're looking to get over 
1Gb, etherchannel should actually work.  It uses a hash based on (I 
believe) source and destination IP and port, so it should roughly 
balance connections between the servers.  The other option, if you're 
using Linux, is to use balance-rr mode on the bonding driver.  This 
should deliver per-packet balancing and the switch doesn't have to know 
anything about the bonding.  Documentation for the bonding driver is here:
