D XPoint is a persistent memory technology from Intel, and
Optane is their brand for products using 3D XPoint memory.
Optane DC Persistent Memory is the brand for Optane products that go in DDR4 memory module slots

Performance wise at least in speed is something around DDR2 667-800. Latency is still 100x high.
supposed to have a latency in the range of hundreds of nanoseconds (0.1-0.99 microsecons),
right now it's in the range of 6-10microseconds (6000-10000 nanoseonds).

In fact a 3D Xpoint DIMM is PAIRED with a RAM DIMM.

Теперь операционные системы надо будет дорабатывать.

If your working memory never loses data, then when you power cycle
you should still be in the exact same state as you left it, with the same apps running.
No need to reinitialize everything

Это как раз сценарий под который разрабатывается Фантом ОС (Д. Завалишин)

real use scenario targeted here are very large, high availability databases.
