– 0%: App Direct Mode
– 1-99%: Mixed Memory Mode
– 100%: Memory Mode
Go to Goals ➙ Memory Mode [%], input the memory percentage, and reboot the system.
Notes:
– Before changing from one mode to another:
1. Back up all the data and delete all the created namespaces. Go to Namespaces ➙ View/
Modify/Delete Namespaces to delete the created namespaces.
2. Perform secure erase on all the installed PMems. Go to Security ➙ Press to Secure Erase to
perform secure erase.
– Make sure the capacity of installed PMems and DRAM DIMMs meets system requirements for the
new mode (see “PMem and DRAM DIMM installation order” in Memory Population Reference).
– After the system is rebooted and the input goal value is applied, the displayed value in System
Configuration and Boot Management ➙ Intel Optane PMems ➙ Goals will go back to the
following default selectable options:
• Scope: [Platform]
• Memory Mode [%]: 0
• Persistent Memory Type: [App Direct]
These values are selectable options for PMem settings, and do not represent the current PMem
status.
In addition, you can take advantage of a memory configurator, which is available at the following site:
http://1config.lenovo.com/#/memory_configuration
Alternatively, set PMem Goals with the following commands in OneCLI:
1. Set create goal status.
onecli.exe config set IntelOptanePMEM.CreateGoal Yes
--imm USERID:PASSW0RD@10.104.195.86
2. Define the PMem capacity that is invested in system volatile memory.
onecli.exe config set IntelOptanePMEM.MemoryModePercentage 20
--imm USERID:PASSW0RD@10.104.195.86
Where 20 stands for the percentage of capacity that is invested in system volatile memory.
3. Set the PMem mode.
onecli.exe config set IntelOptanePMEM.PersistentMemoryType "App Direct"
--imm USERID:PASSW0RD@10.104.195.86
Where App Direct stands for the PMem mode.
– Persistent Memory Type
In App Direct Mode and Mixed Memory Mode, the PMems that are connected to the same processor
are by default interleaved (displayed as App Direct), while memory banks are used in turns. To set
them as not interleaved in the Setup Utility, go to Intel Optane PMems ➙ Goals ➙ Persistent
Memory Type [(PMem mode)], select App Direct Not Interleaved and reboot the system.
Note: Setting PMem App Direct capacity to not interleaved will turn the displayed App Direct regions
from one region per processor to one region per PMem.
