I don’t buy that rational. How often do you think you are going
to turn over an appliance? It is more likely you will add to the pool of
appliances. I know we have never turned over a VTL and only now we are
replacing them with DD’s.

One of the selling advantages of the PureDisk appliances is
that you only buy the de-dupe licenses once. All hardware eventually gets
old. When that happens, you can buy another PureDisk appliance and re-use
your existing de-dupe licenses. You could build your own appliance with
off-the-shelf hardware and re-use the licenses. With a DD, when you
upgrade the hardware, you're re-buying the software again since the prices are
not separate.
When you're doing the cost comparisons, factor in not only
the initial purchase but also subsequent purchases.
I despise per-TB licenses too (as somebody else pointed
out), If I had a choice, I wouldn't buy them and would tend to avoid the
PureDisk licensing model specifically for this reason.
