NetApp Asis dedupe

It is impressive that you can deduplicate on live storage (most systems dedup on backup, or VTL)...

Here are the two caveats I've found:

1) Size of volume limitations.  It depends on CPU/RAM on the Filer, so different models do different things.

2) You really, really, want to be on 7.3.1 and any filers that replicate from it probably want to be on 7.3.1.  7.3.1 right now is new, so that scares some people.

here are the sizes:

Storage system model, Maximum size of volume without deduplication (TB), Maximum size of volume with deduplication (TB), Total data size of volume with deduplication (TB)
