• 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

2. Define the DCPMM capacity that is invested in system volatile memory.

onecli.exe config set IntelOptaneDCPMM.MemoryModePercentage 20

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"

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.

Note: Setting DCPMM App Direct capacity to not interleaved will turn the displayed App Direct regions

from one region per processor to one region per DCPMM.

• 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.

• Namespaces

App Direct capacity of DCPMMs 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.

Each App Direct region can be allocated into one namespace. Create namespaces in the following

operating systems:

– Windows: Use Pmem command.

– Linux: Use ndctl command.

– VMware: Reboot the system, and VMware will create namespaces automatically.

After creating namespaces for App Direct capacity allocation, make sure to create and format filesystem

in the operating system so that the App Direct capacity is accessible for applications.
