HPE ProLiant DL560 Gen10 - NVDIMM Relocation Guidelines; Recovering Restored Data from an NVDIMM-N DRAM

The NVDIMM-N Sanitize options are intended to meet the Purge level.
For more information on sanitization for NVDIMMs, see the following sections in the HPE 16GB NVDIMM User Guide on the
Hewlett Packard Enterprise website (http://www.hpe.com/info/nvdimm-docs):
• NVDIMM sanitization policies
• NVDIMM sanitization guidelines
• Setting the NVDIMM-N Sanitize/Erase on the Next Reboot Policy
NIST SP800-88 Guidelines for Media Sanitization (Rev 1, Dec 2014) is available for download from the NIST website (

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.
• 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 server 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.
