Intel recently released the first commercial server-grade persistent memory (PM), Optane DC Persistent Memory. PM bridges the long-standing gap between volatile and non-volatile storage devices, as its byte-addressability and non-volatility allow it to be used partly as storage and memory simultaneously. One downside of conventional memory management design is that such distinction needs to be made at boot time or explicitly set through a user-level program. This limits the flexibility offered by the device, as data persistence requirements vary over time.
