The NVIDIA® Quantum-2 InfiniBand platform is designed to offer the most advanced networking performance available, specifically for scientific researchers and AI developers working on complex challenges. This platform includes cutting-edge NVIDIA In-Network Computing acceleration engines that deliver ultra-low latency and twice the data throughput. These features make it ideal for use in supercomputers, hyperscale cloud data centers, and artificial intelligence applications that require scalability and a rich set of features.
The NVIDIA Quantum-2 platform takes In-Network Computing acceleration technology to the next level by offering preconfigured and programmable engines. These engines include NVIDIA Scalable Hierarchical Aggregation and Reduction Protocol (SHARP) ™, Message Passing Interface (MPI) tag matching, MPI_Alltoall, and programmable cores. Additionally, the platform offers full transport offload with RDMA, GPUDirect RDMA, and GPUDirect Storage. By providing these features, the NVIDIA Quantum-2 platform is able to deliver the best cost per node and return on investment (ROI).
World-Leading Performance
The NVIDIA Quantum-2 InfiniBand platform is setting new records for high-performance networking, achieving 400Gb/s per port – which is double the bandwidth of the previous generation – and boasting 3 times higher switch silicon port density. It can connect over a million nodes at 400Gb/s in a 3-hop Dragonfly+ topology.
The platform includes the third generation of NVIDIA SHARP technology which offers virtually limitless scalability for large data aggregation through the network and 32 times higher AI acceleration power compared to the previous generation. Additionally, this technology enables multiple tenants or parallel applications to share the infrastructure without any performance degradation. The platform also includes hardware engines for MPI_Alltoall acceleration and MPI tag matching, as well as advanced congestion control, adaptive routing, and self-healing networking features. These enhancements make the NVIDIA Quantum-2 InfiniBand platform ideal for use in high-performance computing (HPC) and AI clusters, enabling them to achieve even greater levels of performance.
NVIDIA Quantum-2 Portfolio
The NVIDIA Quantum-2 platform is designed to provide AI developers and scientific researchers with the fastest networking performance and advanced feature sets, enabling them to tackle the most complex challenges. The platform offers software-defined networking (SDN), In-Network Computing, performance isolation, advanced acceleration engines, remote direct memory access (RDMA), and the highest speeds and feeds available – reaching up to 400Gb/s. This makes NVIDIA Quantum-2 a powerful tool for the world’s leading supercomputing data centers.
400G InfiniBand NDR Switches
NVIDIA Quantum-2 switches are equipped with 64 ports that can support up to 400Gb/s each or split to provide up to 128 ports with 200Gb/s each. The switches come in a compact, 1U fixed configuration with both internally and externally managed options. They offer an aggregated bidirectional throughput of 51.2 terabits per second (Tb/s) and can handle more than 66.5 billion packets per second. The switches can be used in a variety of topologies, including Fat Tree, Dragonfly+, and multi-dimensional Torus.
400G InfiniBand NDR Network Adapters (NIC)
NVIDIA ConnectX®-7 InfiniBand adapters provide 400Gb/s data throughput and support 32 lanes of PCIe Gen5 or Gen4 for host connectivity. They use OSFP connectors for physical connectivity and come in a variety of form factors, including Open Compute Project (OCP) 3.0 with OSFP or QSFP112 connectors, and CEM PCIe x16 with QSFP112 connectors. The ConnectX-7 adapters also include advanced In-Network Computing features such as MPI_Alltoall and MPI tag matching hardware engines, as well as quality of service (QoS), congestion control, and more. Some adapters also have the option to connect an additional 16-lane auxiliary card using NVIDIA Socket Direct™ technology to achieve 32 lanes of PCIe Gen4.
400G InfiniBand NDR Transceivers and Cables
The 400Gb/s InfiniBand (NDR) connectivity provides flexibility in building a preferred topology using connectorized transceivers with passive fiber cables, active copper cables (ACCs), and direct attached copper cables (DACs). MPO fiber cables can be used to create complex infrastructures with easier installation, maintenance, and upgrades.
- Connector options for 400Gb/s InfiniBand include the 8-channel and 4-channel octal small form-factor plug (OSFP) and the 4-channel, quad small form-factor plug 112G (QSFP112).
- Twin-port OSFP transceivers have two separate 400Gb/s NDR transceiver engines inside with two 4-channel, MPO/APC optical connectors.
- Each 4-channel NDR port can be split into two 2-channel, 200Gb/s NDR200 ports using fiber splitter cables.
- Switch-side, twin-port, copper DACs and ACCs are also available in straight or 1:2 or 1:4 splitter cables with single-port OSFP or QSFP112 endpoints to adapters and DPUs.
- The air-cooled Quantum-2 switches only accept twin-port, finned-top, OSFP devices. DGX-H100 InfiniBand four OSFP cages only accept twin-port, flat-top, 800Gb/s transceivers and ACCs. HCAs and DPUs use flat-top OSFP or QSFP112 devices.
The large selection of device combinations creates multiple interconnect choices.
(1) Quantum-2 switches can be connected to HCAs and DPUs using switch-side twin-port, 800Gb/s DACs, ACCs, and transceivers:
- Two 400Gb/s NDR
- Four 200Gb/s NDR200
- Single-port OSFP or QSFP112
(2) Connectivity to previous InfiniBand generations is also possible using Quantum-2 switch twin-port OSFP, 2xHDR DACs and AOCs splitter cables with QSFP56 connector endpoints.
- Two 400Gb/s HDR, two 200Gb/s EDR, or four 100Gb/s HDR100 links to Quantum switches
- ConnectX-6 HCAs
- BlueField-2 DPUs
(3) Flat-top, twin-port, 800Gb/s transceivers and ACC cables can connect DGX-H100 Hopper GPU systems to Quantum-2 switches, creating 400Gb/s NDR GPU compute fabrics with minimal cabling.
