Section 6 – RAID Levels
General:
• Before creating or altering a RAID config, always backup important data
to an external location to prevent accidental data loss.
• A given array should not mix drive types or logical sizes. It is
recommended to only use drives officially supported by Lenovo for the
given platform.
• Each RAID level requires a certain minimum and or maximum number of
drives. If altering the system storage devices after purchase or a
previous configuration, it will be necessary to verify the proper types and
number of devices for a desired RAID configuration have been installed.
Altering or creating an array may require any existing OS to be
reinstalled.
• P3 Tower, P3 Ultra, and P3 Tiny utilize Intel Rapid Storage Technology
(RST) for configuring RAID.
P3 Tower:
• At the time of writing there are no add-in RAID controllers certified on
this platform.
• Only drives in the two onboard Gen 4 M.2 slots can be utilized together
in a RAID configuration. RAID configurations utilizing both onboard and
AIC M.2 drives are not supported.
The table below shows various RAID levels supported on each P3 platform.

in the two onboard M.2 slots, reducing max number of supported M.2 NVMe
drives to one (installed in an add-in card). See reference picture in Section 4.
