Although the system can support a wide array of configurations of
NVMe and SATA drives, care should be given when selecting drives
based on the types of RAID arrays that are desired.
o A given array should not mix drive types or sizes. Mixing drive
brands does not pose any issues so long as the brands share the
same Lenovo part numbers.
o Each RAID level requires a certain minimum and or maximum
number of drives. If altering the system storage devices after
purchase, it will be necessary to verify there are the proper types
and number of devices for a desired RAID configuration.
o In the proper configuration, the system can hold up to eleven
NVMe M.2 drives and the system supports the Gen 4 PCIe
standard for the latest generation of M.2 drives. The two
designated slots on the motherboard can support up to Gen 4
speeds. However, the currently supported optional Quad M.2
PCIe card and the single M.2 Add In Card are only capable of
Gen 3 speeds, even if Gen 4 drives are used.
There are Lenovo limitations on the number of supported RAID arrays.
o There is a maximum of two RAID arrays per RAID controller. This
will limit the NVMe RAID controller to two arrays and limit the
SATA RAID controller to two arrays for a total of 4 RAID arrays
per system.
o RAID arrays on the NVMe RAID controller are limited to a single
interface. An array could be created with both M.2 drives in the
on-board M.2 slots. An array could also be created on a single
Quad M.2 PCIe adapter using up to 4 M.2 drives but an array
cannot span interfaces or adapters.
