You don't necessarily need a switch to support it.  One can use alb mode
in Linux on any old switch and it works reasonably well other than for
some excessive ARP traffic.  However, as we found out the hard way when
building our Nexenta SAN, bonding works very well with many-to-many
traffic but does very little to boost one-to-one network flows.  They
will all collapse to the same pair of NICs in most scenarios and, in the
one mode where they do not, packet sequencing issues will reduce the
bandwidth to much less than the sum of the connections.  Take care -
