How about pricing a 10/100 Ethernet switch with one Gigabit port for your main network switch, then put a gigabit card in your server? Many server motherboards these days come with gigabit NICs built in - but of course you might not have that luxury. I would seriously price this up before channel bonding. Also, you say you are using NFS. Have you looked at the network traffic in detail, using tools like Ethereal and ntop? Are you SURE the 100Mbps link is the bottleneck? NFS, especially with that number of clients, is probably your major problem. Have you tried some NFS tuning, using utilities like nfsstat? I've done work in the past with performance on big NFS servers - you might find that the problem is made better by increasing RAM so you get much bigger buffer spaces. How much RAM is in your server, may I ask?
