300U to 8U

Sun has released an interesting Blue Prints document, detailing how they replaced 3x Sun Enterprise 10k boxes(approximately 80U) and a Sun Fire E6500, with 4x T2000(2U) boxes, that is pretty impressive.

I guess this means there are going to be lots of large Sun boxes coming onto the used market.
