DDR4 SDRAM - single-channel DDR4 SDRAM memory with 8 components of 8 bit + ECC (64bit + 8bit ECC), 8/16GB @2400MT/s.
BlueField SoC The BlueField SoC integrates four, eight or sixteen 64-bit Armv8 A72 cores interconnected by a coherent mesh network, one DRAM controller, a dual port RDMA intelligent
Ethernet adapter supporting up to 100Gb/s, an embedded PCIe switch with endpoint and root complex functionality, and up to 8 lanes of PCIe Gen 3.0/4.0.
Overlay Networks 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
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. NVIDIA BF1500 Controller Card effectively addresses this by providing advanced NVGRE and VXLAN hardware offloading engines that encapsulate and
de-capsulate the overlay protocol.otocol.
RDMA and RDMA
overConverged
Ethernet (RoCE)
NVIDIA BF1500 Controller Card, utilizing IBTA RDMA (Remote Data Memory Access) and RoCE (RDMA over Converged Ethernet) technology, delivers low-latency and high-
performance over Ethernet networks. Leveraging data center bridging (DCB) capabilities as well as advanced congestion control hardware mechanisms, RoCE provides
efficient low-latency RDMA services over Layer 2 and Layer 3 networks.
NVIDIA
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. NVIDIA BF1500 Controller Cardadvanced acceleration technology enables higher cluster efficiency
and scalability to tens of thousands of nodes.
