@cld9731, the art of benchmarking is a combination of facts, half-truths and wild claims. Most companies are guilty of all three, and it's difficult to find clear winners. My rule of thumb is twicew as fast for half the price - that usually stops debate.
The key on Violin's new product isn't speed and price, as you suggest. It's the fact that Windows Storage Server is fully integrated, and that this ties in withWindows Server being easily interfaced to it.
For reference, look at the new SMB release and what it does when connected to Windows.
For Fusion IO, the quaestions is what it is compared with. Oracle's Ellison claims 100x performance inmprovement for in-memory databases, compsred with HDD solutions. Does that work better than Fusion's 30x? And does it cost more?
