This will really lower competition in the SAN space. Only a few viable vendors left. Nimble was one of the few major players.
I disagree. What about Tintri, Kaminario, or Tegile? There are still plenty of vendors out there in Nimble's competitive tier. I mean they don't compare to HDS or IBM but again, Nimble is a completely different use case.
Honestly I think it would have made more sense for HPE to acquire Tintri for their portfolio at a reasonable price. Nimble is awesome for its own use case, but the acquisition seemed to be just one of appeasement to shareholders.
Unless they are shifting gears and trying to get more competitive in small-medium markets as an all around vendor (aside from adding Nimble, thinking of them purchasing Aruba a couple years ago as well).
