NVDIMM identification
NVDIMMs are supported only when first-generation Intel Xeon Scalable processors are installed on the server blade.
NVDIMM boards are blue instead of green. This change to the color makes it easier to distinguish NVDIMMs from DIMMs.
To determine NVDIMM characteristics, see the full product description as shown in the following example:
