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.
