No I don't - Gigabyte Technology made the first one (they called it the 
i-RAM) and I recall seeing another manufacturer's version a few weeks 
back.  Hopefully Google can help there.

The Gigabyte one is actually a PCI card which has a SATA connector on 
it, so you plug that from the PCI card onto the motherboard's SATA 
connector.  Not quite sure how that would work with hotswap SATA drives 
etc.  They have a CD-ROM size version too, but that probably won't fit 
in many servers.  Wikipedia has a bit on it.

Cheers,
Adam.
