Configuring RoCE for SR-IOV VF Devices (VF RDMA)
The following sections describe how to configure RoCE for SR-IOV VF devices
(also referred to as VF RDMA). Associated information and limitations are also
provided.
Configuration Instructions
To configure VF RDMA:
1. Install the VF RDMA capable components (drivers, firmware, multiboot
image (MBI)).
2. Configure QoS for VF RDMA.
QoS configuration is needed to configure priority flow control (PFC) for
RDMA. Configure QoS in the host as documented in “Configuring QoS for
RoCE” on page 259. (QoS configuration must be done in the host, not in the
VM).
3. Configure Windows Hyper-V for VF RDMA:
a. Enable SR-IOV in HII and on the Advanced tab in Windows Device
Manager.
b. Open the Windows Hyper-V Manager on the host.
