NIST SP800-88 Guidelines for Media Sanitization (Rev 1, Dec 2014) is available for download from the NIST
website (http://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-88r1.pdf).
NVDIMM relocation guidelines
Requirements for relocating NVDIMMs or a set of NVDIMMs when the data must be preserved
• The destination server hardware must match the original server hardware configuration.
• All System Utilities settings in the destination server must match the original System Utilities settings in the
original server.
• If NVDIMM-Ns are used with NVDIMM Interleaving ON mode in the original server, do the following:
◦ Install the NVDIMMs in the same DIMM slots in the destination server.
◦ Install the entire NVDIMM set (all the NVDIMM-Ns on the processor) on the destination server.
This guideline would apply when replacing a system board due to system failure.
If any of the requirements cannot be met during NVDIMM relocation, do the following:
◦ Manually back up the NVDIMM-N data before relocating NVDIMM-Ns to another server.
◦ Relocate the NVDIMM-Ns to another server.
◦ Sanitize all NVDIMM-Ns on the new server before using them.
Requirements for relocating NVDIMMs or a set of NVDIMMs when the data does not have to be
preserved
If data on the NVDIMM-N or set of NVDIMM-Ns does not have to be preserved, then
• Move the NVDIMM-Ns to the new location and sanitize all NVDIMM-Ns after installing them to the new
location. For more information, see NVDIMM sanitization on page 136.
• Observe all DIMM and NVDIMM population guidelines. For more information, see DIMM and NVDIMM
population information on page 131.
• Observe the process for removing an NVDIMM.
• Observe the process for installing an NVDIMM.
• Review and configure the system settings for NVDIMMs. For more information, see Configuring the
server for NVDIMMs on page 136.
HPE Persistent Memory option
HPE Persistent Memory, which offers the flexibility to deploy as dense memory or fast storage and features
Intel Optane DC Persistent Memory, enables per-socket memory capacity of up to 3.0 TB. HPE Persistent
Memory, together with traditional volatile DRAM DIMMs, provide fast, high-capacity, cost-effective memory
and storage to transform big data workloads and analytics by enabling data to be stored, moved, and
processed quickly.
