Sanitize erase—When you sanitize erase a drive, you remove all sensitive information from a physical drive. Information
removed includes nonvolatile media, nonvolatile cache, bad blocks, and overprovisioned areas. Sanitize erase operations
cannot be stopped after starting, and the drive will continue to sanitize after a hot-plug or server reboot. During the
sanitize erase operation, the drive is unusable until after the process is complete. If the operation fails, you are only allowed
to start another sanitize operation, or, if the drive is under warranty, you can return it to HPE.
NOTE: The sanitize erase method satisfies the requirements for the purge action set by the National Institute of Standards
and Technology. For more information about the purge action, see "Guidelines for Media Sanitization" at the U.S.

Sanitize overwrite (HDD)—Sanitize overwrite fills every physical sector of the drive with a pattern, and includes the
following benefits:
◦
Removes all sensitive information from the drive.
◦
Once started, the drive continues to sanitize regardless of resets and power cycles.
•
Sanitize block erase (SSD)—Sanitize block erase sets the blocks on the drive to a vendor-specific value, removing all user
data, and includes the following benefits:
◦
Removes all sensitive information from the drive.
◦
Once started, the drive continues to sanitize regardless of resets and power cycles.
Server profile mobility
A server profile can be moved to any compute module within the frame. The logical drive or logical JBOD associated with that
server profile will automatically move to the destination compute module.
The following table describes the differences in the controllers for managing the front drives.
Controller
Drive location
Server profile mobility
P408i-c or S100i
Internal
Yes—Requires moving internal drives manually.
P416ie-m or P542D Internal
No
P416ie-m or P542D D3940
Yes
The HPE Synergy 12Gb SAS Connection Module supports HPE Synergy D3940 Storage Modules located within the frame.
Server profile mobility is limited to a single frame.
Logical JBOD drive selection
HPE OneView creates logical drives and logical JBODs for the server profile using the following drive selection algorithm. After
the server profile is created, the drive bay is continuously assigned even when drives are removed or replaced by cycling
through the following steps.
NOTE: The maximum logical JBOD limit is 108 per Synergy frame. This number includes external logical drives.
1. Locates a candidate list of unassigned drives that match the server profile input of drive technology and drive capacity.
2. Attempts to select a contiguous group of candidate drives located within a single HPE Synergy D3940 Storage Module.
3. Attempts to select a noncontiguous group of candidate drives located within a single HPE Synergy D3940 Storage Module.
4. Attempts to select a noncontiguous group of candidate drives located across multiple HPE Synergy D3940 Storage
Modules.
