Ethernet
(RoCE)
ConnectX-6, utilizing IBTA RDMA (Remote Data Memory Access) and RoCE (RDMA over Converged
Ethernet) technology, delivers low-latency and high-performance over InfiniBand and Ethernet
networks. Leveraging datacenter bridging (DCB) capabilities as well as ConnectX-6 advanced
congestion control hardware mechanisms, RoCE provides efficient low-latency RDMA services
over Layer 2 and Layer 3 networks.
NVIDIA
PeerDire
ct™
PeerDirect™ communication provides high efficiency RDMA access by eliminating unnecessary
internal data copies between components on the PCIe bus (for example, from GPU to CPU), and
therefore significantly reduces application run time. ConnectX-6 advanced acceleration
technology enables higher cluster efficiency and scalability to tens of thousands of nodes.
CPU
Offload
Adapter functionality enables reduced CPU overhead leaving more CPU resources available for
computation tasks.
