Well, for one thing since iSCSI is designed for SAN use, the filesystem
can safely assume that nothing else is accessing it concurrently and do
a lot more aggressive caching. NFS has to play it safe and check with
the server every time a file is accessed to make sure it hasn't changed.
It sounds to me like the OP is thinking about servers in a large data
center booting off an iSCSI SAN. Makes migrating off of dead hardware
to a new machine (or even a VM) a snap.
also, the TOE cards are not that cheep either :-) my 2c, danny
They're usually cheaper than fibre channel HBAs though ;-)
