Since combining ZFS storage backend, via nfs or iscsi, with ESXi

1G Ether is so cheap, but not as fast as desired. 10G ether is fast
enough, but it’s overkill and why is it so bloody expensive?
10G switches are expensive because the fabric and physical layer chips
are expensive. You have to use dedicated switch fabric chips for 10GE
(and there's only a couple of vendors for those) and even with those,
the number of ports is limited. These cost factors have limited 10GE
ports to the more up market layer 3 and above switches.
Low cost layer 2 mainly software options aren't there (yet!).
