Are Blade Server all Hype?
There has been heas of articles on blade servers in the tech press.
I think it is all about size. Blade servers are nifty because you can mount say ten vertically in the space of a 6u rack mount. This seemed to be a hot topic back when there were drastic dot-com needs. Maybe it is still a need for crowded data centers and the occasional super computer builder.
One nice thing about modern blade servers is that they can share power supplies and network adapters between multiple nodes. If you've wired up a rack of machines that are dual homed to a standard switch, you know what a mess that can become.

Blades are not a "be all and end all" general replacement for servers at all, but rather are something to consider when your best method for expanding a system is to scale outwards (e.g. over many low to moderate power systems) rather than to scale upwards (e.g. one hyper-powerful system).
I agree that it's all about size. Rack space at a hosting facility can be expensive, and staying with a more modest half or whole rack instead of expanding out into a second rack can very well make up for the cost of using blades.

Blade servers are useful for:
Companies who make them probably love blade servers. You have a high initial cost (which is OK because they are hyped) and then a vendor lock-in once you've purchased the first cage.
yes they are.
