It's NetApp Jim .. but not as we know it.

I smiled to myself when I read the comment "Is NetApp officially saying this??? This is so not-like NetApp",
The things which NetApp have been working on in across the portfolio including ONTAP, FAS, FlashRay, StorageGrid Webscale, Workflow Automator (WFA), and the rest of the ONCOMMAND software suite, have all been converging to this point for what seems like a really long time. Until now, at best we've only been able to give hints about what's we'd be releasing and what this means. Now that waiting is done, and I think you'll see NetApp do a bunch of things you'd never expect.
As far as "All-flash FAS will offer 350,000 IOPS at less than 1.3msecs latency", while I wasn't at the press briefing, those figures sound about right. In ONTAP 8.2, All Flash FAS already outperforms most "purpose built" flash arrays at a lower price point, with 8.3 (which is a free and _Non Disruptive_ software upgrade for Clustered Data ONTAP) customers should see significant additional latency improvements, especially those running on the latest FAS8000 platforms.
If you were surprised by this, just wait, there's a lot more coming :-)
