• 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).
HPE Persistent Memory supports the purge level using a cryptographic erase technique and an overwrite technique.
HPE ProLiant and HPE Synergy Gen10 server products support sanitizing HPE Persistent Memory modules during POST. Use
the HPE RESTful Interface Tool or UEFI System Utilities to schedule sanitization on the next boot.
