Re: NUMA, not SSD
Not really. NVMe and PCI(e) memory mapping provide a good transitional step. By memory-mapping the NVM, it can already treated like a slow memory under specific conditions (the 64-bit address space assures we shouldn't run out of mapping space anytime soon). It's just not done that way right now due to "habit". Once more devices see the NVM as less a drive and more a memory, then the OS logic will be in place and the hardware can take the next step to move it from an I/O bus to a memory bus (preferably distinct from the DRAM bus so they're not locked together). From there, it's just a matter of the OS supporting it after it's already used to the idea.
