• Goals
– Memory Mode [%]
Select this option to define the percentage of DCPMM capacity that is invested in system memory, and
hence decide the DCPMM mode:
– 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. Make sure the capacity of installed DCPMMs and DRAM DIMMs meets system requirements for
the new mode (see "DCPMM installation order" on page 71).
2. Back up all the data and delete all the created namespaces. Go to Namespaces ➙ View/
Modify/Delete Namespaces to delete the created namespaces.
3. Perform secure erase on all the installed DCPMMs. Go to Security ➙ Press to Secure Erase to
perform secure erase.
– After the system is rebooted and the input goal value is applied, the displayed value in System
Configuration and Boot Management ➙ Intel Optane DCPMMs ➙ 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 DCPMM settings, and do not represent the current DCPMM
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 DCPMM Goals with the following commands in OneCLI:
1. Set create goal status.
onecli.exe config set IntelOptaneDCPMM.CreateGoal Yes
--imm USERID:PASSW0RD@10.104.195.86
2. Define the DCPMM capacity that is invested in system volatile memory.
onecli.exe config set IntelOptaneDCPMM.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 DCPMM mode.
onecli.exe config set IntelOptaneDCPMM.PersistentMemoryType "App Direct"
--imm USERID:PASSW0RD@10.104.195.86
Where App Direct stands for the DCPMM mode.
– Persistent Memory Type
In App Direct Mode and Mixed Memory Mode, the DCPMMs 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 DCPMMs ➙ Goals ➙ Persistent
Memory Type [(DCPMM mode)], select App Direct Not Interleaved and reboot the system.
