I'm not sure that I see Tintri as a competitor to Tegile. They're both hybrid storage, true, but Tintri is purpose-built for virtual machine storage, and Tegile is presumably for general-purpose block storage. Tintri would arguably not be suited for high-volume, high transaction workloads. Conversely, the other vendors are right in Tegile's sights, although Nimble is arguably lower-end as an iSCSI-only array. EMC and NetApp, on the other hand, are ripe for the picking, since they have both failed to deliver a really compelling hybrid storage product so far, and most pure-play flash storage is still too expensive for people who need high capacity. I think Tegile's approach is pretty compelling, although, as always, one has to discover how the product performs in the real world.
