• If the existing configuration is fully or partly in App-Direct mode and new PMEM is also in App-Direct mode, then
ensure that all PMEMs are at the latest matching firmware level and also re-provision the PMEMs by creating a new
goal.
• If the existing configuration and the new PMEM are in different modes, then ensure that all PMEMs are at the latest
matching firmware level and also re-provision the PMEMs by creating a new goal.
To use the compute node's BIOS Setup Utility, see
BIOS Setup Utility Menu for PMEM, on page 54

Potential data loss: If you change the mode of a currently installed PMEM from App Direct or Mixed Mode
to Memory Mode, any data in persistent memory is deleted.
Caution
PMEMs can be configured by using the compute node's BIOS Setup Utility or OS-related utilities. To use the
BIOS Setup Utility, see the section below.
The compute node BIOS Setup Utility includes menus for PMEMs. They can be used to view or configure
PMEM regions, goals, and namespaces, and to update PMEM firmware.
To open the BIOS Setup Utility, press
F2
when prompted during a system boot.
The PMEM menu is on the Advanced tab of the utility:
Advanced > Intel Optane DC Persistent Memory Configuration
From this tab, you can access other menu items:
•
DIMMs
: Displays the installed PMEMs. From this page, you can update PMEM firmware and configure
other PMEM parameters.
•
Monitor health
•
Update firmware
•
Configure security
You can enable security mode and set a password so that the PMEM configuration is locked. When
you set a password, it applies to all installed PMEMs. Security mode is disabled by default.
•
Configure data policy
•
Regions
: Displays regions and their persistent memory types. When using App Direct mode with
interleaving, the number of regions is equal to the number of CPU sockets in the compute node. When
using App Direct mode without interleaving, the number of regions is equal to the number of PMEMs
in the compute node.
From the Regions page, you can configure memory goals that tell the PMEM how to allocate resources.
