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:

Notes:
• Before setting up RAID for NVMe drives, follow the below steps to enable VROC:
1. Restart the system. Before the operating system starts up, press the key specified in the on-screen
instructions to enter the Setup Utility. (For more information, see the "Startup" section in the LXPM
documentation compatible with your server at
lxpm_product_page.html
2. Go to System settings ➙ Devices and I/O Ports ➙ Intel VMD and enable the option.
3. Save the changes and reboot the system.
• VROC Intel-SSD-Only supports RAID levels 0, 1, 5, and 10 with Intel NVMe drives.
• VROC Premium requires an activation key and supports RAID levels 0, 1, 5, and 10 with non-Intel NVMe
drives. For more information about acquiring and installing the activation key, see

Validate the power requirements for your configuration using the latest version of the Power Configurator to
ensure that the number of power supplies selected are adequate for supporting your chassis configuration.
The Power Configurator tool can be found at
CAUTION:
Failure to validate the configuration with the Power Configurator tool could result in system errors,
failure to power on, or microprocessor throttling, and limiting system's ability to leverage all the
microprocessor performance.
