1.HQ-BOX2 supports Intel's RAID (using VROC plug) with the following HW devices that can be added to the array(s)
i.  PCIE GEN4 CPU  NVME  -> up to 4 disks
ii. PCIE GEN3 PCH  NVME  -> up to 4 disks 
iii.SATA 

2.To enable HQ-BOX2 RAID install the appropriate disks and ensure VROC plug is attached to the extension card inside and do as below:
i.Enter BIOS pressing F2->Setup Utility
ii.Enter CPU PCIE x16 Configuration->IIO Configuration-> Intel VMD technology-> Intel VMD for Volume Management Device on Socket 0
iii. Here one can find two different sections:
     - VMD config for PCH ports -> allows to configure up to 4 chipset PCH PCIE Gen3  NVME disks
     - VMD config for IOU 0     -> allows to conifgure up to 4 CPU PCIE Gen4 NVME disks

iv.To enable VMD config for PCH ports  -> change "Enable/disable VMD" to "Enable"
    Now one can push listed PCIE Root Ports (Gen3) to the RAID device space by switch to "Enable" for specific disk(s)
    The mapping is as follow:
    PCH Root Port 0 - upper left  PCIE x4 NVME disk
    PCH Root Port 3 - upper rigth PCIE x4 NVME disk
    PCH Root Port 5 -  internal M2.E PCIE x1 NVME disk
    PCH Root Port 8 -  internal M2.M PCIE x4 NVME disk
v.To enable VMD config for IOU 0  -> change "Enable/disable VMD" to "Enable"
    Now one can push listed PCIE Root Ports (Gen4) to the RAID device space by switch to "Enable" for specific disk(s)
    The mapping is as follow:
    VMD Port A - 2nd left (down row)  PCIE x4 NVME disk Port 0:0
    VMD Port B - 1st left (down row)  PCIE x4 NVME disk Port 0:1
    VMD Port C - 3rd left (down row)  PCIE x4 NVME disk Port 0:2
    VMD Port D - 4th left (down row)  PCIE x4 NVME disk Port 0:3
vi.Afer changing to "Enabled" exit to the Main Menu by pressing "Esc" then enter "Exit" menu -> "Exit Saving Changes" ->"Yes" and wait for the reboot.

3.After restart Enter BIOS again by pressing F2->Device Management->Intel(R) Virtual RAID on CPU
Now one can enter "All |Intel VMD Controllers and setup desired RAID (1 or 2) by choosing RAID Level and adding appropriate disks
