Switch configuration recommendations for iWARP-based deployments (converged and non-converged)

  • Switch configuration recommendations for network switches in iWARP-based deployments

    This document consists of switch configurations for all Internet Wide-area RDMA Protocol (iWARP) based deployments. The Azure Stack HCI Engineering team recommends that you use Pause Flow for all iWARP-based deployments on switch ports that are used for RDMA & Management/VM traffic.

    Note: For a high I/O environment, such as an all-NVMe configuration where you might require a DCB (PFC) configuration, see Microsoft HCI Solutions from Dell Technologies: Switch Configurations - RoCE Only (Mellanox Cards).
