Good Technology, An Unfortunate Ending
Disclaimer = Pure Storage Employee
This is truly an unfortunate outcome. At one point in time Tintri understood the challenges of disk-based SANs and envisioned the opportunity to radically change storage operations in support of a VMware (and latter Hyper-V & OpenStack) private cloud.
In some regards they took what NetApp established and advanced the innovation. For a brief period in time, there was no simpler storage to operate with VMware, yet Tintri never seemed to cross the chasm or establish escape velocity.
Personally, I believe Tintri suffered due to a lack of a direct competitor - one who would validate the market they were trying to establish. Tintri was unique and ultimately undefined.
I sincerely wish nothing but the best for all who participated in the Tintri journey. Many friends and colleagues invested their blood sweat and tears to bring their technology to market.
