 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.
