The NetApp NetCache uses ONTAP OS as well; which has this blurb in their deployment guide... could probably find the same thing for their Filers as well.

That is, Nope, ONTAP is *not* Unix-based. I believe they started with a real-time kernel and wrote the rest from scratch - it may look very BSD-like on the surface, and it follows a lot of Unix conventions so that Unix admins could very quickly learn to admin the machines. But, for example, ONTAP services NFS requests right in the network interrupt handler - which is how they post SPEC SFS numbers with ORT < 1.0ms... Of course, ONTAP has grown into a far more complex OS in version 7.x than it started out as; early versions were very "lean and mean", but feeping creaturitis has set in over the years... but while it is Unix-like, it is definitely not a Unix-based OS. -- Chris
