    Huh, interesting that it doesn't have those end connectors on the MB. I didn't pay attention.
    Well I've got some testing to do with it and see if it works for what I need it to do.
    Right now I have my current node running with E5-2680 but its eating up a bit too much power for what I want to use it for, so I have E5-2670 coming to see if I can lower the power usage a bit before I build out a cluster without the blade chassis.

    This is a fun board to play with as long as you have all of the proper parts like the PSU, cabling, CPU's, heat sinks, etc...

    Sounds like a fun project you did there.

    I am looking to build a cluster of these servers to do some home lab testing.
    I actually figured out how to boot this board into a WinPE environment through the PXE -> iPXE process.
    Eventually I will get this hooked up to my FreeNas iSCSI storage through iPXE boot so I don't have to have any drives in them and with being able to add a 10GB NICs, you can build a pretty powerful compute node that can be hooked up to some external storage system over RDMA which I've already figured out how to setup.

    Good afternoon. I also decided to assemble a computer based on the C8220X board, the one that has 2 SATA connectors near the front connector SAS. Who can check these connectors at work? Whoever connected GPGU Tesla to this board? Who-Nibut figured out what the other contacts of the control connector do except the two-pin contact board and the PC_ON? Controlling the fans? Indicators HDD/Power?
    Sorry for the bad language, I'm writing through an interpreter.

    That board that I bought 083N0 and I do not want to use the SAS mezzanine, I need built-in HDD controllers, the board's length is critical. The version of the motherboard of its BIOS, I can verify only after receiving the parcel and connecting it. Now I ask what other owners of C8220 083N0 could use to take advantage of the ports on the board and the connectors.

    Though thanks for the tip to the SAS board. It does not increase the length, the main thing is that it does not interfere with the installation of GPGU-modules on the PCI-e slots.

    Which HDD can be connected to mini-SAS and SAS-mezzanization of this board? Of those that can be bought as SATA. Usual for NAS-systems of household or server SSD Intel? And what cables are needed for this?

    Good day.
    The postal delivery from Taiwan exceeded itself and led me a cable with a riser to connect it to the C8220 board.
    Here are the photos.

    In which connector does it connect to the board?

    Where to buy a wire with a connector for this power supply to the riser? It is the same +12 volts closer to the motherboard and the outer case?

    The fee came surprisingly fast.

    I correctly connected the GPGU riser to it?

    Do these two SATA connectors work as usual, without a special SAS board?

    Here is the result of researching the connector of the board's additional power supply with a tester and reviewing your photos.

    [​IMG]

    The black wires of the small connector on the photo are in the connector on the board connected directly. Probably it is a "minus supply". But with the black wires of the main power connector they are connected through some kind of resistance.
    The yellow wire of the small connector is connected directly to the yellow wires +12 volts of the large connector, but not connected to +12 vsb.
    Red wire is most likely +5 volts supply.
    For complete certainty, you need to look where the second red wire leads to the photo.
    And if not difficult, tell me where to buy molex milli-grid 51110-1251 female through which the board is turned on and a control signal is sent to the power supply.
    I can just solder the wires to the pins of the connector but it's wrong.

    but this is a circuit trap ... this small connector on the side.
    The contact that I counted +5 volts is connected to the black wires of the large connector and the minus supply of the connector of the usb
    In general, it is incomprehensible and it is better not to use it.
    Perhaps this is a connector to power the control devices outside the board, from its converter, because the power supply of the server Dell has only +12 volts.
    I need a measurement on the running board, but I do not have any processors, power adapter and memory yet.
    The connector on your photo is small - it's a connector of 2 hard drives

    Спасибо, все понятно и доходчиво про питание.
    Где бы еще разъем 51110-1251 купить мамы...
    И я слегка не понял, разъемы SATA те что что синие кабели идут на плату SAS на меззонине - получают питание от маленького разъема того? Они без нее как простые SATA работать могут?

    I bought 2 processors E5-2603 for tests as the cheapest, they are installed correctly?

    Good afternoon.
    I still did not understand on version 1.0 without an additional fee could podkjuchit hdd? via ports on the motherboard or through an external pci-e controller?
    sorry for my English, it's all Google's fault.

    Good day to all. Today I bought two coolers under LGA2011 which can be adapted for C6220 and C8220 so that they do not interfere with installing the RAM.
    To do this, remove the fan from the cooler, and gently cut off the excess part of the aluminum projections with the mounting holes, leaving enough to allow the use of the clamp. Better yet, make notes by putting the cooler on top of the inserted memory slots, then you can see exactly how much you need to saw off.
    The second necessary refinement - the fixing screws of the radiators have a long thread for the sockets on our boards, you need to remove the restrictive washers from the scoop that prevent the screws from popping out, and thread two M4 nuts onto the thread. The remaining part of the thread is sufficient for fixing in the socket mounts and there is no risk of damaging the board with the ends of the screws.
    (I did experiments with another radiator and almost damaged it because of the long screws, I hope I did not hurt, I can only check when the power adapter is delivered).
    After that, simply install the radiator holding and tighten the screws all tightly, put on the fan and rejoice in the computer cooling without interfering with the installation of all the slats of the main memory.
