Any options for FDR Infiniband or 40 GbE on the Mac Pro 2012?

    What options are available for high performance interconnects for the Mac Pro 2012? Is any of Mellanox's gear supported on Mac? Ideally I'm looking for RDMA or RoCE support.

    Chelsio's T580 is a 40GbE QSFP+ PCIe adapter with driver support for macOS.
    I haven't personally used the T580, but I've run some T520 and S320 in a MacPro5,1 under macOS and they've worked very well.

    The T580-CR supports RDMA and RoCE, but I'm not sure about the current state of the macOS driver's support for that. They also have a beta version of the driver that supports their newer T6 ASIC (up to 100GbE).

    A new T580-LP-CR is available for $400 directly from Chelsio or half of that on eBay, which blows my mind.

    ATTO's FastFrame NIC also provides 40GbE QSFP+ support under macOS. Historically, their drivers have been solid.

    10 G will nearly saturate PCIe 2.0 x4.
    40 G will nearly saturate PCIe 2.0 x16.

    The QPI link between northbridge and CPU(which hosts the memory controllers) is 6.4GB/s, or 51.6 gigabit.

    Just FYI.
