Does anyone know any technical details behind this paragraph? Specifically, are they talking about a new kind of interconnect technology with low power over ~1m distance?

(Searching for "rackspace virtual I/O" was not so useful.)

"Rackspace is leading an effort to build a “virtual I/O” protocol, which would allow companies to physically separate various parts of today’s servers. You could have your CPUs in one enclosure, for instance, your memory in another, and your network cards in a third. This would let you, say, upgrade your CPUs without touching other parts of the traditional system. “DRAM doesn’t [change] as fast as CPUs,” Frankovsky says. “Wouldn’t it be cool if you could actually disaggregate the CPUs from the DRAM complex?”"
