“Our Storage Array Is Compatible with VMware…” Says Who?

I talk to dozens of companies every week, and every one says the same thing: “Our product is compatible with VMware!” But not everyone’s definition of “compatible” is the same, and some are not compatible (I couldn’t resist) with the requirements of production data centers.
