    Bootable VROC RAID 10, VMD domains, and PCIe lanes

    Intended Hardware/RAID Setup:

    As I understand it from this picture, bootable RAID arrays have a maximum of 4 supported drives because they must reside within a single VMD domain and non-bootable arrays can span multiple VMD domains.

    I don't know how VMDs are distributed on this board so I don't know if the arrays can be configured in this way:

    Onboard:
    M.2_1 (lower M.2 slot, too short for a 905P) Data drive 7
    M.2_2 (upper M.2 slot, shares bandwidth with the U.2 port and may be PCH only) No drive

    DIMM.2:
    M.2_1 Boot drive 1
    M.2_2 Boot drive 2

    M.2 x16 Card 1:
    M.2_1 Boot drive 3
    M.2_2 Boot drive 4
    M.2_3 Data drive 1
    M.2_4 Data drive 2

    M.2 x16 Card 2:
    M.2_1 Data drive 3
    M.2_2 Data drive 4
    M.2_3 Data drive 5
    M.2_4 Data drive 6

    Will this configuration work?

    Also, the CPU supports 44 PCIe lanes and there will be an x16 graphics card, how many 970 EVOs would need to be cancelled to keep the graphics card running at a full x16?

    You'll have to drop one Hyper X16 card in order to run x16 on the other one. If you run a Hyper X16 at X8 you will only see 2 drives.

    You would be better served running all the 905P's in the Hyper X16 and put the Data drives on the Dimm.2

    The Asus X299 Sage WS or X299 Sage/10G uses the PLX 8747 Pcie switches and would allow X16 to the GPU and both Hyper X16 cards.

    imho


    I currently run the R6 Apex with 8 1&2 TB Samsungs on board without Raid.

    I run 2 HyperX16s both run at x16 with 4 divided x4 lanes. I had to put my GPU in a x8 slot to accomplish this.

    One note I use intel 900p SSDs, 8 of them. Not sure about the samsungs working maybe with a VROC key?

    BTW the controllers worked this way for me, there are 3, Controller 0 1st HyperX16, Controller 1 2nd HyperX16, Controller2 DIMM Card (I have a single Samsung 960 Pro in that card)

    I am not sure your config will work, but if it does you will be spanning contollers. And I know you cannot boot off spanned controllers, well at least it is not supported. So I don't think your configuration will work or at least you shouldn't do it even if you found a way to get the spanned controllers to boot (maybe there is a hack) your OS won't upgrade properly in the future. It will be painful to do.

    Thanks guys. I would like to keep the graphics card at x16 so it seems like my options for the non-bootable data array are to either have less drives and continue using this motherboard, or switch to the X299 Sage/10G and keep all of the drives but lose a few extras that this motherboard has.

    I prefer this motherboard so I think I'll go with that and perhaps make the non-bootable data array out of SATA drives in a non-VROC RAID.
