Comment on Available on Google Cloud: Intel Optane DC Persistent Memoryparent

Comments

The persistent part is that it's persistent across reboots.

So does that mean it can be considered persistent like a regular SSD/HDD?

Yes. It's durable storage with a RAM interface. Byte-addressable through conventional CPU load/store instructions. It follows the usual cache coherence protocols for memory, but once it gets flushed, it's stable—just like conventional storage devices.
