huh?
Is this so that a server can loose power and once its back on things start up right where things left off?
What about data stuck in the CPU or in-between the CPU and IO bus, or one of the many other places that data can get temporarily cached as it moves thru a system board?
At 8GB per DIMM and 128GB max per server, its certainly not a storage technology.
Not bashing it, just not understanding its use case.
