From a hardware perspective, it's interesting. The selling point of VRTX is that everything is built-in. For a small company that doesn't have a server room or the capabilities of hosting several servers, VRTX has four blades. The equivalent in regular server models would be four servers, which is a minimum of 4U, but it could easily be 8U, and then it would have storage. The storage is included inside the enclosure, and it would require a storage unit. It would also require connectivity, which would be ethernet or another protocol switch.
From a software perspective, it's a little bit more integrated. You have an integrated way of managing the whole thing, including storage and networking. It has an internal network that can also be useful. I know for a fact that Dell is almost fazing out the product, and it is not that available anymore because it will just cannibalize their sales. They want to sell the more expensive stuff.
