Brian,
In reagards to the Solaris NFS issue, I've heard it is the other way around. UDP with Solaris and the filers is a loser but TCP works well. I have actually experienced that myself and my SE said it was a known issue with Solaris, Netapp, and <insert switch vendor here>. It's only a problem with the Solaris NetApp combo though, NFS over UDP that is Solaris to Solaris worked fine for me.
As far as I'm concerned, this is an urban legend :-) I use UDP v3 on Solaris with NetApp, and I've always had a good performance, no worse than Linux or HPUX. When you say you experienced it yourself, what exactly did you see? Was it reproducible with iozone? What were the numbers?
Thanks
