Thought you might be interested in hearing that my company this month has just released a new blade for it's BX600 chassis...

This blade can now have up to the following;

8 x AMD Opteron 885 (DC 2.6GHz 2MB)
128GB RAM (16GB dedicated for each processor)
8 x Gig E NICs
4 x HBAs
2 x SATA HDDs (SAS soon)
Optional module which allows 4 more GigE NICs

...and you can have two of these in the 7u chassis and still have room for either a further 4 socket blade or two 2 socket blades!

The clever stuff is that if you have four 2 socket or two 4 socket AMD 800 series blades you can now join them together with an optional HT connection kit to make this 8 socket blade with no latency penalties compared with the new dedicated 8 socket blade.

...it's bit of a monster to say the least!
