Alternatively, change the selectable percentage with the following command in OneCLI:
onecli.exe config set IntelOptaneDCPMM.PercentageRemainingThresholds 20
--imm USERID:PASSW0RD@10.104.195.86
Where 20 is the selectable percentage.
RAID configuration
Using a Redundant Array of Independent Disks (RAID) to store data remains one of the most common and
cost-efficient methods to increase server's storage performance, availability, and capacity.
RAID increases performance by allowing multiple drives to process I/O requests simultaneously. RAID can
also prevent data loss in case of a drive failure by reconstructing (or rebuilding) the missing data from the
failed drive using the data from the remaining drives.
RAID array (also known as RAID drive group) is a group of multiple physical drives that uses a certain
common method to distribute data across the drives. A virtual drive (also known as virtual disk or logical
drive) is a partition in the drive group that is made up of contiguous data segments on the drives. Virtual drive
is presented up to the host operating system as a physical disk that can be partitioned to create OS logical
drives or volumes.
An introduction to RAID is available at the following Lenovo Press website:

Install the operating system
Several options are available to install an operating system on the server.
• Lenovo XClarity Administrator
If you are managing your server using Lenovo XClarity Administrator, you can use it to deploy operating-
system images to up to 28 managed servers concurrently. For more information about using Lenovo
XClarity Administrator to deploy operating system images, see:
http://sysmgt.lenovofiles.com/help/topic/com.lenovo.lxca.doc/compute_node_image_deployment.html
• Lenovo XClarity Provisioning Manager
Lenovo XClarity Provisioning Manager is used to install operating system of single server. You can
complete operating system installation by following the instructions in Lenovo XClarity Provisioning
Manager OS Installation function.
• Install the operating system manually
If you cannot install the operating system through Lenovo XClarity Administrator or Lenovo XClarity
Provisioning Manager, you can install the operating system manually. For more information about
