Implementing Intel Optane DC Persistent Memory on Windows Server 2019

Intel Optane DC Persistent Memory is based on Intel 3D XPoint non-volatile memory technology and is implemented in Lenovo® ThinkSystem™ servers. The use of DC Persistent Memory Modules (DCPMMs) enables software applications to take advantage of the larger memory capacities, data persistence and the resulting improved performance of the server.

This document shows how Microsoft Windows implements persistent memory, how to configure and manage DCPMM on Windows Server 2019, and how to utilize it in Hyper-V.

The intended audience of this document is IT professionals, technical architects and software engineers. It is expected that readers have some knowledge of persistent memory and the using Windows Server tools such as PowerShell and Task Manager.
