NIST SP800-88 Guidelines for Media Sanitization (Rev 1, Dec 2014) is available for download from the NIST website (http://

NVDIMM relocation guidelines
Requirements for relocating NVDIMMs or a set of NVDIMMs when the data must be preserved
• The destination graphics expansion module hardware must match the original graphics expansion module hardware
configuration.
• All System Utilities settings in the destination graphics expansion module must match the original System Utilities settings
in the original graphics expansion module.
• If NVDIMM-Ns are used with NVDIMM Interleaving ON mode in the original graphics expansion module, do the following:
◦ Install the NVDIMMs in the same DIMM slots in the destination graphics expansion module.
◦ Install the entire NVDIMM set (all the NVDIMM-Ns on the processor) on the destination graphics expansion module.
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 graphics expansion module.
◦ Relocate the NVDIMM-Ns to another graphics expansion module.
◦ Sanitize all NVDIMM-Ns on the new graphics expansion module 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.
• Observe all DIMM and NVDIMM population guidelines. For more information, see
DIMM and NVDIMM population
information.
• 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 graphics expansion
module for NVDIMMs .
Recovering restored data from an NVDIMM-N DRAM
CAUTION: Do not remove an NVDIMM when any LEDs on any NVDIMM in the system are illuminated. Removing an
NVDIMM when an LED is illuminated might cause a loss of data.
CAUTION: Electrostatic discharge can damage electronic components. Be sure you are properly grounded before
beginning this procedure.
