Introduction
DellEMC’s NVDIMM-N Persistent Memory is a disruptive Storage Class Memory technology that enables unprecedented
performance improvement over legacy storage technologies. Each NVDIMM-N provides 16GB of nonvolatile memory and has
the same form factor as a standard 288-Pin DDR4 DIMM. The NVDIMM-N resides in a standard CPU memory slot, placing
data close the processor. With its ability to operate at 2666MT/s DDR4 data rates, the NVDIMM-N takes full advantage of the
high bandwidth and extremely low latency that is characteristic of the memory bus. For comparison, the table below provides
approximate data access times for DDR4 relative to other server storage media.
Table 1. Storage Technology
Storage Technology Data Access Time
15K SAS Disk ~ 6,000,000 ns
SATA SSD ~ 120,000 ns
NVMe SSD ~ 60,000 ns
DDR4 NVDIMM-N ~ 150 ns
This document provides an overview of the DellEMC NVDIMM-N Persistent Memory solution. It is intended to help the user
with initial set-up and configuration, providing information on system behavior when NVDIMM-Ns are installed. This document
will also help the user to become familiar with NVDIMM-N manageability and error handling. And lastly, it introduces the user to
NVDIMM-N basic setup and configuration in a variety of supported operating systems.
