We did a big upgrade of our Netapps as well about a year ago, and seriously looked at the Sun solution. What held us back up quotas and the lack of them. Or more accurately, the lack of quotas (even if they were unlimited) meant that we couldn't *quickly* generate reports showing which user(s) were taking up the most disk space. I did download and play with the Sun VMware image they offer for testing, built some volumes, etc. But the quota/reporting issues kept us from the Sun solution. If you don't have anything already, and you want a nice large Box, I think you could do alot worse than the Sun/Oracle stuff. And ZFS with snapshots is very interesting too. And it should be rock solid with NFS server as well.

On the other hand, Netapp's are rock solid, they just run and run and run. And disks are super simple to swap out when they do fail. I love the stability on the boxes, I've been using them since OnTap 4.x and the F330/F740 days. Good stuff. BlueArc is another vendor to possibly look at too. Oh, one of the killer limitations with Netapp is that the maximum Volume size is 16Tb - overhead. Can't go past that. And backups are sucky unless you do NDMP directly to tape. But then restores suck suck suck because NDMP is just an encapsulation of the native dump/restore tools, which means scanning the tapes bit by bit to find and restore the file(s) you want to restore. So in that case, snapshots make a huge difference. Except when they expire and the user comes the next day with a restore request. This is one of the biggest things that people overlook when they deploy storage like this, restore speed for single files. We used to just backup the Filers over NFS with EMC/Legator Networker, which wasn't so fast on backup, but restores for single files were quick and *easy*. And the file indexes lastest forever, which was nice because you could easily browse them looking for what you wanted. I'd be happy to write even more about how I hate all backup products if you like.
