Persistent Memory Module Sanitization - HP Enterprise ProLiant DL380 Gen10 Maintenance And Service Manual

Persistent memory module sanitization

Persistent memory module
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 over-provisioned 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).
Intel Optane persistent memory for HPE supports the purge level using a cryptographic erase technique and an overwrite technique.
HPE ProLiant and HPE Synergy Gen10 server products support sanitizing persistent memory modules during POST. Use the HPE
RESTful Interface Tool or UEFI System Utilities to schedule sanitization on the next boot.
