I have heard from our HPE Storage representatives that this product is going end of life. I have heard that in the past and it turned out that the version was EOL and they released a new version. I think the reps just want us quoting and selling more Nimble storage. I asked for them to send me documentation stating that it is EOL and have received nothing.
We love this software, it works really well. The adaptive optimization is a really great feature to get more IOPS.
