User Manual

The server can be configured for NVDIMMs using either of the following:
• UEFI System Utilities—Use System Utilities through the Remote Console to configure the server for
NVDIMM memory options by pressing the F9 key during POST. For more information about UEFI System
Utilities, see the Hewlett Packard Enterprise website (http://www.hpe.com/info/uefi/docs).
• iLO RESTful API for HPE iLO 5—For more information about configuring the system for NVDIMMs, see
https://hewlettpackard.github.io/ilo-rest-api-docs/ilo5/.
NVDIMM sanitization
Media sanitization is defined by NIST SP800-88 Guidelines for Media Sanitization (Rev 1, Dec 2014) as "a
general term referring to the actions taken to render data written on media unrecoverable by both ordinary
and extraordinary means."
The specification defines the following levels:
• Clear: Overwrite user-addressable storage space using standard write commands; might not sanitize data
in areas not currently user-addressable (such as bad blocks and overprovisioned areas)
• Purge: Overwrite or erase all storage space that might have been used to store data using dedicated
device sanitize commands, such that data retrieval is "infeasible using state-of-the-art laboratory
techniques"
• Destroy: Ensure that data retrieval is "infeasible using state-of-the-art laboratory techniques" and render
the media unable to store data (such as disintegrate, pulverize, melt, incinerate, or shred)
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 (

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

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:
