(from my post on the Gartner blog...)
For a Gartner analyst to take these results and simply put them in a table as "comparable" is borderline irresponsible.
As Rob stated, this wasn't apples-apples, or even apples-pears. In SolidFire's case, the capacity used for this workload was 0.2% of the storage system, and even PEAK performance was only 10% of guaranteed IOPS.
You could easily put 7500 users on the same configuration for the same price, or, more likely, put dozens of other workloads on the same system with Guaranteed QoS, rather than add "yet another island" of storage for VDI.
The test situation may not have been ideal, but I don't fault Citrix. They aren't the one putting all the results in a table that implies they are comparable - because they aren't. They simply post the whitepapers so that you get the full context of each test.
Also, fwiw, in addition to the questionable pricing on the "lowest priced" result, it also isn't an HA configuration. Anyone recommending a non-HA storage system for a 750 user VDI workload needs to get their head examined.
