• 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:
– For Memory Mode:
1. Set create goal status.
OneCli.exe config set IntelOptanePMEM.CreateGoal Yes
--bmc USERID:PASSW0RD@10.104.195.86
2. Define the PMEM capacity that is invested in system volatile memory.
OneCli.exe config set IntelOptanePMEM.MemoryModePercentage 100
--bmc USERID:PASSW0RD@10.104.195.86
Where 100 stands for the percentage of capacity that is invested in system volatile memory.
– For App Direct Mode:
1. Set create goal status.
OneCli.exe config set IntelOptanePMEM.CreateGoal Yes
--bmc USERID:PASSW0RD@10.104.195.86
2. Define the PMEM capacity that is invested in system volatile memory.
OneCli.exe config set IntelOptanePMEM.MemoryModePercentage 0
--bmc USERID:PASSW0RD@10.104.195.86
Where 0 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"
--bmc USERID:PASSW0RD@10.104.195.86
Where App Direct stands for the PMEM mode. You can input App Direct for App Direct
interleaved or App Direct Not Interleaved for App Direct not interleaved.
– Persistent Memory Type
In App Direct 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.
• Regions
After the memory percentage is set and the system is rebooted, regions for the App Direct capacity will be
generated automatically. Select this option to view the App Direct regions per processor.
• Namespaces
App Direct capacity of PMEMs requires the following steps before it is truly available for applications.
1. Namespaces must be created for region capacity allocation.
2. Filesystem must be created and formatted for the namespaces in the operating system.
