BlueField-2 IPU The BlueField-2 IPU integrates eight 64-bit Armv8 A72 cores interconnected by a coherent mesh network, one DRAM controller, an RDMA intelligent network adapter
supporting up to 200Gb/s, an embedded PCIe switch with endpoint and root complex functionality, and up to 16 lanes of PCIe Gen 3.0/4.0.
Overlay In order to better scale their networks, data center operators often create overlay networks that carry traffic from individual virtual machines over logical tunnels in
Networks encapsulated formats such as NVGRE and VXLAN. While this solves network scalability issues, it hides the TCP packet from the hardware offloading engines, placing higher
loads on the host CPU. BlueField BF2500 DPU Controller effectively addresses this by providing advanced NVGRE and VXLAN hardware offloading engines that encapsulate
and de-capsulate the overlay protocol.
RDMA and RDMA BF2500 card, utilizing RDMA (Remote Data Memory Access) and RoCE (RDMA over Converged Ethernet) technology, delivers low-latency and high-performance over Ethernet
over Converged networks. Leveraging data center bridging (DCB) capabilities as well as advanced congestion control hardware mechanisms, RoCE provides efficient low-latency RDMA
Ethernet (RoCE) services over Layer 2 and Layer 3 networks.
PeerDirect® 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. BlueField BF2500 DPU Controller advanced acceleration technology enables higher cluster efficiency
and scalability to tens of thousands of nodes.
Quality of Support for port-based Quality of Service enabling various application requirements for latency and SLA.
