You are welcome to follow the Recommended Network Configuration Examples for RoCE Deployment for our recommendations and instructions. There are several industry standard network configuration for RoCE deployment.

ECN is an optional feature that may be used between two ECN-enabled endpoints when the underlying network infrastructure also supports it. ECN allows end-to-end notification of network congestionВ without dropping packets. Explicit Congestion Notification (ECN)Д®xplicit Congestion Notification (ECN) is an extension to the Internet ProtocolВ and to the Transmission Control ProtocolВ and is defined in RFC 3168В (2001). PFC can provide different levels of service to specific classes of Ethernet traffic (using IEEE 802.1p traffic classes). The goal of this mechanism is to ensure zero loss under congestion in data center bridging(DCB) networks, and to allow, as a sample, for prioritization of RoCE traffic over TCP traffic. Priority Flow Control (PFC) IEEE 802.1Qbb applies pause functionality to specific classes of traffic on the Ethernet link. Although the RoCE protocol benefits from the characteristics of a converged Ethernet network, the protocol can also be used on a traditional or non-converged Ethernet network.

RoCE v2 is an internet layerВ protocol which means that RoCE v2 packets can be routed.

RoCE v1 is an Ethernet link layerВ protocol and hence allows communication between any two hosts in the same Ethernet broadcast domain. There are two RoCE versions, RoCE v1 and RoCE v2. RDMA over Converged Ethernet (RoCE)В is a network protocol that allows remote direct memory access(RDMA) over an EthernetВ network.

Installer Privileges: The installation requires administrator privileges on the target machine.ДЈ.
