Mainstream players
I question whether Tintri, Kaminario, and Infinidat count as "mainstream." AFAIK, they're still wobbling along in the second tier, in the sense that they are not really household names in the storage world. I'm on the fence about Pure: they certainly have name recognition, but it's not clear whether they can actually make a profit. As for HPE . . . they have name recognition, but does anyone actually run physical HPE arrays?
