Windows refers “Storage Class Memory (SCM) “as persistent storage that is directly installed on the memory bus. NVDIMM-N is a form of Storage class memory.
DellEMC PowerEdge platforms implement NVDIMM-N root device using PNP ID “ACPI0012”, this root device contains individual NVDIMM-N devices. During boot process windows loads “Storage Class memory bus driver (Scmbus.sys) for this root device. Scmbus.sys driver enumerates each NVDIMM-N device in the system and loads scmdisk0101.sys as functional driver for each NVDIMM-N device.
DellEMC NVDIMM-N in Windows Server 2016 and 2019 environment can support both block mode and direct access mode (DAX) mode. The following two videos describe the difference between these two modes and how use each mode.
