IMO, it would be possible to make a system that uses both, but it is a much more challenging proposition. You need to have a chipset, BIOS, mobo and OEM willing to work with you, and time to market would be in years.


Maybe not so challenging. Current multi socket Opteron systems are already NUMA systems, and the operating systems are already NUMA aware. You could put DRAM in the DIMMS connecting to one of the CPU sockets, and EcoRAM in all the others. The only thing that isn't yet in place is telling the OS not to use the EcoRAM for normal operations. And your applications would have to be adapted to read their data from the EcoRAM NUMA memory pool, but since search is all custom software, this is probably not much of a problem.
