They work fine! Best performance is to be had if you run an OS / network card that supports jumbo ( 9kB ) packets.

If you're running *nix, then mount options are important... for Solaris...

rw,bg,hard,intr,rsize=32768,wsize=32768,proto=tcp,forcedirectio,noac,vers=3

The important options being:
forcedirectio: Bypasses the file system cache for all reads and writes
noac: Disables attribute caching on client side tcp: Mount the file system using the proto=tcp option

The first two options stop the server trying to fight with the Netapp server over who's best at IO... the server just gives up.
