How to Build a Non-Volatile Memory DBMS

"Non Volatile Memory" really means Intel's "3D X-point" memory-- estimated availability of this product for system memory is 2018-ish.

There is also MRAM [0] which ships from a company called Everspin [1][2] and is produced by Globalfoundries. Unlike Intels/Microns solution it seems to be as fast as normal RAM, but at much smaller densities.

HP has NVDIMMs that you can order for the DL series of servers. I'm waiting on a POC machine with 16GB of NVDIMM right now.

Optane is on sale now.

Optane's performance is hardly on par with SSDs, let alone DRAM.

XPoint is expected to have performance much higher than Optane.

Optane is the "marketing name" the technology behind Optane is 3D-XPoint.

The Optane available currently isn't in DIMM-format which is expected to give a further boost though.

This is true. Bypassing the page cache and VFS will be a net win. But all my storage needs can't be done in MMAPs
