Persistent-Memory

• Storage-Class Memory: Intel Optane, 3D XPoint, and the Lessons of a Bold Failure · 2025-08-15

  The technology, the programming model, and the performance characteristics of Intel Optane — and why the most promising memory technology in a generation failed commercially despite delivering exactly what it promised.

• Persistent Memory Programming: DAX Mappings, PMDK Libraries, Crash Consistency Without Write-Ahead Logging, and the Optane Legacy · 2021-06-14

  A deep exploration of persistent memory — how DAX enables direct byte-addressable access to non-volatile memory, how the PMDK libraries solve the crash consistency problem at the instruction level, and the lessons of Intel Optane.
