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:
