In a typical setup you will configure the ARX to ignore .snapshot
directories. F5 doesn't know anything about NetApp snapshots nor does it
manage any NetApp functionality like snapshots.

What the customers means from snapshot support is that once a file moves
to other storage it also clears the blocks which are being held by
previous snapshots for that specific file. Is that what Acopia does?

Appreciate your response.

Excuse me. Maybe that has changed since the last time I worked with a
ARX box.

Patently incorrect, Stefan.

ARX coordinates snapshots from multiple vendors including NTAP and
creates a virtual snapshot across different arrays - a function that no
other technology can provide.

I don't see how the Acopia can do that without having to nuke the
entire snapshot, as well as having full control over the blocks on the
Netapp.

Now maybe the Acopia can intercept and translate where files are and
make it look transparent, but I'd be hesitent to trust it.

And still, the biggest issue is backups, esp NDMP backups of your
data, and then doing restores properly.
