Oracle^® Dual Port 25 Gb Ethernet Adapter User's Guide

Install RoCE in Windows Kernel Mode

RoCE functionality is available in user mode and kernel mode application. Starting with the Windows Server 2012 release, the RDMA capability in the NIC for SMB file traffic is enabled if both ends are enabled for RDMA. Broadcom NDIS miniport bnxtnd.sys starting with version 20.6.2 supports RoCEv1 and RoCEv2 with the NDKPI interface. The default setting is RoCEv1.

1. Upgrade the NIC NVRAM using the appropriate board packages. In CCM or in UEFI HII, enable support for RDMA.
2. Enable each miniport.

   You can go to the adapter's Advanced Properties page and set Network Direct Functionality to Enabled for each BCM5741X miniport.

   You can also run this command in the PowerShell window:

   Set-NetAdapterAdvancedProperty -RegistryKeyword *NetworkDirect -RegistryValue 1

3. Verify that RDMA is enabled.

   These PowerShell commands return true if Network Direct is enabled.
