I am confused as to your reason for equating "enterprise" and "windows" as
if there are no enterprise supported NAS's that run non-windows operating
systems.

As one example there is the Snap Server http://www.snapserver.com/ which
runs GuardianOS (Linux)

I have gotten real knee deep with the OS and (owner at the time) Adaptec
support to resolve some partitioning/RAID problems. They were able to assist
and bring about complete data recovery thanks to their non-windows
enterprise support. The support is optional.
