RDMA over Converged Ethernet (RoCE)
ConnectX-2 EN with RoCE utilizes advances in Data Center Bridging (DCB) to enable efficient
and low cost implementations of RDMA over Ethernet, supporting the entire breadth of RDMA
and low latency features. This includes reliable connected service, datagram service, RDMA and
send/receive semantics, atomic operations, user level multicast, user level I/O access, kernel
bypass, and zero copy.
ConnectX-2 EN with RoCE based network management is the same as that for any Ethernet and
DCB-based network management, eliminating the need for IT managers to learn new technolo-
gies.
