Shorty, the smaller brother of HP c7000 Blade enclosure is now available. The new c3000 is targetted towards SMB. It is a very compact enclosure, with only eight half-height slots compared to the C7000 16 slots. To achieve this size, some power options are not available.
All the server blades, interconnect options are currently reuseable on the c3000. For more info see here and a excellent video site
