It's my (ca. 4-year-ancient) recollection that the write requests are
written to a split NVRAM buffer; when one half hits the high-water mark
(or a timer pops, whichever happens first), the "active half" of the
buffer is switched, and the half that had been written to has its
entries committed to disk.
So basically, yes -- the NetApp shouldn't lose data. (But "files"
aren't written to the NVRAM; it's fairly raw write requests that get
written.)
Cheers,
david
