AFAIK they run a heavily modified NetBSD, but at least it's some sort of BSD. ;-) In fact I'm very satisfied with NetApp filers and their WAFL system. We have NetApp Filer clusters in production at customers, they exhibit exceptional reliability, even if a disk, a disk shelf, or an entire filer head fails, the cluster keeps running. Not to mention that it submits a support mail automatically and you get the replacement without having to do anything yourself. I'm afraid it is not possible to implement such a redundant NFS cluster with FreeBSD. Not to mention snapshots ... Years before FreeBSD intro- duced snapshots, WAFL supported them, and they work a whole lot better. Creating a snapshot takes just a few seconds, and file system access never freezes during that period. It works so well that you can create hourly snapshots for simple "undelete" usage without affecting the usability and performance of the file system at all.
