Exadata comes to mind... in fact I guess exadata really is just "a bunch of JBOD arrays with resiliency in software". Honestly, IMHO, "enterprise storage" is overpriced these days. Oracle exadata is just proving the point that you can build the same thing yourself for a fraction of the cost on commodity hardware. Of course they overprice exadata too, and probably make a killing on it...
