Doom doom doom
It's a shame that Violin really seemed to misjudge the market. They had an excellent play for super low-latency applications, but it turns out that market isn't that big, and their initial pricing was way too high for people who didn't need the bleeding-edge performance. Their prices have come down now, but Flash storage has come down generally, so Violin is maybe at parity with other players but without any special sauce to distinguish them, arguably apart from performance. On the flip side, you can get better performance now from other vendors than used to be possible, vendors who seem to be less obviously doomed.
