X6250 two or four socket two or four disk

I have been looking on sunsolve at the relatively new sunblade 6000 system and am a little confused on the X6250 page there is a picture of a blade with four processor sockets and two 2.5inch drive bays now all of the specs say that the x6250 has two CPU sockets and four drive bays. Which is it and what is the picture of?
