Abstract
Lenovo has engineered ThinkSystem servers incorporating second-generation Intel Xeon Scalable processors to take advantage of features provided by Intel Optane DC Persistent Memory.
This paper describes the overall implementation of DC Persistent Memory Modules (DCPMMs) on Lenovo ThinkSystem. The paper describes the supported modes, the population requirements when both DDR4 DIMMs and DCPMMs are installed, the health monitoring features and both out-of-band and in-band management of DCPMMs.
This paper assumes that the reader is familiar with standard server memory DIMMs and how DIMMs are typically used in servers. The reader will learn how to use Intel DCPMMs as storage as well as volatile memory on a Lenovo ThinkSystem server.
