    Connect-IB MTT

    zack0908

      I have a fat node which has 2TB memory. With the new Connect-IB card, I want to increase the MTT, so I could register a large memory region. I found this post for HowTo Increase Memory Size used by Mellanox Adapters , but it didn't mention how to increase that for Connect-IB. Could anyone give me any suggestion?

          Hello,

          Have you tried seeing that you cannot actually allocate DMA of the requires size with the default settings ? The parameters in mlx4 (ConnectX-3Pro and below) were configurable as the default values on some occasions were too low for some users. The mlx5 driver should have a much larger default pool.
