You can quickly provision and pre-provision all of your servers using a consistent configuration.
Configuration settings (such as local storage, I/O adapters, boot settings, firmware, ports, and Lenovo
XClarity Controller and UEFI settings) are saved as a server pattern that can be applied to one or more
managed servers. When the server patterns are updated, the changes are automatically deployed to the
applied servers.
Specific details about updating firmware using Lenovo XClarity Administrator are available at:
http://sysmgt.lenovofiles.com/help/topic/com.lenovo.lxca.doc/server_configuring.html
• Lenovo XClarity Controller
You can configure the management processor for the server through the Lenovo XClarity Controller Web
interface, the command-line interface, or Redfish API.
For information about configuring the server using Lenovo XClarity Controller, see:
"Configuring the Server" section in the XCC documentation compatible with your server at

Memory module configuration
Memory performance depends on several variables, such as memory mode, memory speed, memory ranks,
memory population and processor.
Information about optimizing memory performance and configuring memory is available at the Lenovo Press
website:

In addition, you can take advantage of a memory configurator, which is available at the following site:

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:
