AI Clusters Cabling Guide

09-04-2026 - AI Clusters Cabling Guide Introduction 1.1 Overview As AI clusters like NVIDIA H100 require over 10 times more fiber than traditional data centers, cluster cabling provides a well-planned, standardized infrastructure that enables scalable and reliable connectivity for high-performance GPU computing. This approach ensures long-term investment protection by supporting seamless upgrades to 800G and beyond while reducing installation time and minimizing human errors. 1.2 Benefits High Performance & Low Latency Delivers ultra-low latency and high-throughput communication by enabling direct GPU-to-GPU memory access. This bypasses the CPU and kernel, reducing overhead to accelerate distributed training and inference. Advanced implementations achieve over 98% of single-cluster computing efficiency even across distributed data centers. Fast Deployment Accelerates time-to-production by simplifying cluster bring-up. Solutions offer unified namespaces and intelligent data streaming, allowing workloads to run against existing datasets without complex migrations. Pre-validated architectures and integrated stacks enable deployment in minutes rather than months. Simple Architecture, Lower Risk Reduces architectural complexity and vendor lock-in by leveraging open standards like RoCE and UALink. This allows integration into existing Ethernet environments and supports multi-vendor hardware, mitigating the risk of dependency on a single proprietary ecosystem. Proven Delivery & Scalability Ensures robust scalability and reliable delivery for large-scale AI factories. Solutions support clusters scaling from thousands to tens of thousands of GPUs using non-blocking, fat-tree topologies. Technologies like packet spraying and advanced congestion control guarantee predictable performance and efficient resource pooling across the entire infrastructure. 1.3 AI Network Fabrics Here is a comprehensive overview of the four types of AI networks. Network Type Compute Fabric Storage Fabric In-Band Management Network Out-of-Band Management Network Primary Role GPU-to-GPU communication (Training/RDMA) Dataset access & Checkpointing Server hardware control (BMC/IPMI) Network gear configuration (Console) Typical Connection Boundary GPU Server ↔ Leaf ↔ Spine (Within Pod) GPU Server ↔ Storage Gateway/Arrays Server Mgmt Port ↔ Mgmt Switch (In-Rack) Console Ports ↔ Terminal Server ↔ Mgmt LAN Preferred Media Fiber (400G/800G - MMF/SMF) Fiber (100G/400G - MMF/SMF) Copper (Cat6A/8 - 1G/10G) Copper (Serial) + Fiber (Uplinks) 1.3.1 Compute Fabric The compute fabric (also called GPU fabric or backend network) provides ultra-high bandwidth, low-latency connectivity exclusively for GPU-to-GPU communication during AI training and inference. It handles parallel data transfers like AllReduce operations with stringent requirements for lossless, RDMA-capable networks (RoCEv2 or InfiniBand). In typical architectures, each GPU server connects with 8x400G links to leaf switches in a rail-optimized Clos topology, prioritizing minimal latency above all other network functions.

Compute InfiniBand Fabric for Full 127-node DGX SuperPOD Note: Available in OM4 and OS2 Connectivity. 1.3.2 Storage Fabric The storage fabric connects GPU servers to shared external storage infrastructure for dataset access and model checkpointing. It operates at 100G to 200G speeds, with each server typically using a single dedicated storage adapter rather than the multiple connections used in the compute fabric. This fabric significantly impacts AI workflow efficiency by enabling fast data ingest and checkpoint operations, often leveraging parallel file systems like WEKA that offload TCP processing for higher throughput. AI集群直连架构图_存储网络.jpg Figure 2. InfiniBand Storage Fabric Logical Design Note: Available in OM4 and OS2 Connectivity. 1.3.3 In-Band Management Network The in-band management fabric distributes AI/ML jobs onto the data center backend network, prioritizing and allocating GPU, storage, and network resources for applications. Operating at 100GbE to 200GbE speeds, it handles the large data transfers required to feed each GPU with processing tasks. This network shares the data plane but is logically separated for job scheduling and resource orchestration purposes. AI集群直连架构图_带内管理.jpg Figure 3. In-band Ethernet Network Note: Cat6 28AWG Snagless (U/UTP) PVC CM for 1 Gbps Connectivity. (Blue Line) 1.3.4 Out-of-Band Management Network The OOB management fabric provides a dedicated, isolated control plane for infrastructure administration, separate from all data traffic. Using 1GbE copper connections (RJ45/Cat6) to access server iDRAC/BMC ports, console ports, and management interfaces on switches and storage devices, it enables secure remote access even when the primary network fails. This failsafe path allows engineers to recover systems, override automation, and maintain human oversight of the AI infrastructure. 20260330-150421.jpg Figure 4. Logical OOB Management Network Layout 1.4 DGX SuperPOD Architecture In this design, every GPU in the cluster is assigned a unique "rail" number. The Host Channel Adapter (HCA) corresponding to that specific rail number on every GPU server is connected to the same dedicated Leaf switch. For example, all HCA ports 1 from all 32 servers connect to Leaf switch 1, all port 2 HCA ports connect to Leaf switch 2, and so on. This ensures that traffic for a given rail is evenly distributed and never crosses to another Leaf switch within the SU, guaranteeing a non-blocking, predictable communication path for every GPU. 1.4.1 Scalable Unit (SU) The fundamental building block of the NVIDIA DGX SuperPOD is the Scalable Unit (SU). An SU is designed as a modular, repeatable unit that enables rapid, predictable scaling of the AI cluster. For architectures based on systems like the DGX H100 or H200, a single SU comprises 32 DGX GPU servers. To achieve a rail-optimized topology for maximum performance, this configuration pairs 8 InfiniBand Leaf switches, one per network rail. 画板 10.jpg 1.4.2 Cabling Hierarchy Levels The physical cabling within a DGX SuperPOD follows a three-level cluster hierarchy to create a non-blocking fat-tree network topology. This ensures predictable latency and high bisection bandwidth essential for AI workloads. Level A: Server ↔ Leaf Switch (Intra-Rack / Adjacent Rack) This level represents the first hop in the network. Each GPU server connects to all Leaf switches within the SU. These connections are typically short, high-speed links residing within the same or an adjacent rack, forming the foundation of the rail-optimized design. Level B: Leaf Switch ↔ Spine Switch (Cross-Aisle / Cross-Row) This level interconnects the Leaf switches within an SU to the Spine switches. It provides the path for communication between GPU servers within the same SU but connected to different Leaf switches. These cables often run longer distances, connecting racks across an aisle or row. Level C: Spine Switch ↔ Core Switch (Cross-Data Hall / Cross-Row) In larger SuperPOD configurations that scale beyond a single SU, this level connects the Spine switches from multiple SUs to a central Core switch layer. This enables high-speed, low-latency communication between GPUs across different SUs, allowing the entire cluster to function as a single massive compute resource. 1.4.3 Rail-Optimized Cabling A defining characteristic of the DGX SuperPOD network architecture is its "rail-optimized" design. This topology is critical for maximizing the performance of collective communication operations (e.g., All Reduce) during distributed training.

In some cases, this cabling type may also be used to connect switches—for example, Leaf-to-Spine or Spine-to-Core. However, it is not recommended for point-to-point connections between switches if they are physically located in different areas of the data center. 2.2.1 Duplex Direct Single Port to Single Port 1.jpg Data Rate Fiber Mode 1 2 3 400G to 400G OS2 QSFP112-FR4-400G SMLCDX or HD-SMFULCDX QSFP112-FR4-400G Twin-port to Twin-port 1 副本.jpg Data Rate Fiber Mode 1 2 3 1.6T to 1.6T OS2 OSFP-2FR4-1.6T SMLCDX or HD-SMFULCDX OSFP-2FR4-1.6T 800G to 800G OS2 OSFP-2FR4-800G SMLCDX or HD-SMFULCDX OSFP-2FR4-800G Twin-port to Single Port 1 副本 2.jpg Data Rate Fiber Mode 1 2 3 800G to 2x400G OS2 OSFP-2FR4-800G SMLCDX or HD-SMFULCDX QSFP112-FR4-400G 2.2.2 Parallel Direct Single Port to Single Port 1 副本 3.jpg Data Rate Fiber Mode 1 2 3 400G to 400G OS2 OSFP-DR4-400G-FL 12FMTPSMF OSFP-DR4-400G-FL OM4 OSFP-SR4-400G-FL 12FMTPOM4 OSFP-SR4-400G-FL 200G to 200G OM4 QSFP-SR4-200G 12FMTPOM4 QSFP-SR4-200G Twin-port to Twin-port 1 副本 4.jpg Data Rate Fiber Mode 1 2 3 1.6T to 1.6T OS2 OSFP-DR8-1.6T 12FMTPSMF OSFP-DR8-1.6T 800G to 800G OS2 OSFP-DR8-800G 12FMTPSMF OSFP-DR8-800G OM4 OSFP-SR8-800G 12FMTPOM4 OSFP-SR8-800G Twin-port to Single Port 1 副本 5.jpg Data Rate Fiber Mode 1 2 3 1.6T to 2x800G OS2 OSFP-DR8-1.6T 12FMTPSMF OSFP224-DR4-800G-FL 800G to 2x400G OS2 OSFP-DR8-800G 12FMTPSMF OSFP-DR4-400G-FL OM4 OSFP-SR8-800G 12FMTPOM4 OSFP-SR4-400G-FL Twin-port to Single Port with Breakout 1 副本 6.jpg Data Rate Fiber Mode 1 2 3 800G to 4x200G OS2 OSFP-DR8-800G 8FMTPSMF OSFP-DR4-400G-FL OM4 OSFP-SR8-800G 8FMTPOM4 OSFP-SR4-400G-FL Scenario Applications 3.1 Cabling Scenarios In the NVIDIA DGX SuperPOD architecture, the network fabric is organized into three distinct link types based on the hierarchical position within the fat-tree topology. These links form the backbone of the high-bandwidth, low-latency communication required for distributed AI training workloads. The Server↔Leaf connections (Level A) handle GPU-to-network access, Leaf↔Spine connections (Level B) provide intra-cluster aggregation, and Spine↔Core connections (Level C) enable scalability across multiple Scalable Units (SUs) or facilitate data center north-south traffic. Each level has unique requirements regarding data rates, optical module form factors, and cabling infrastructure. 3.2 Server ↔ Leaf (Level A) The Server-to-Leaf link represents the initial access layer of the compute fabric, connecting each DGX system's network interface cards (NICs) to the Leaf switches within the same Scalable Unit. For DGX H100-based SuperPODs, each server typically utilizes OSFP transceivers on the ConnectX-7 NIC side, operating at 400G rates per port. These connect to the Leaf switches (e.g., the NVIDIA Quantum QM9700), which typically use QSFP-DD transceivers at the switch ports. The physical medium for these connections is generally multi-mode fiber (MMF) jumpers, often using MTP®/MPO connectors to support the parallel fiber count required for 400G SR4 optics. In some short-reach, intra-cabinet scenarios, Direct Attach Copper (DAC) or Active Optical Cables (AOC) may also be utilized for their simplicity and low power consumption. This layer typically uses point-to-point cabling due to the short distances involved, which minimizes insertion loss and supports high-density server front ends. In the picture, we visualize a Server Rack with 4 servers, each with its own Rails. On the right, we find the Leaf Switch Rack with 8 Leaf Switches, one for each Rail. As we know, these Quantum-2 switches allow for 32 Twin MTP®/MPO-8/12 APC ports, meaning each switch can support up to 64 individual connections. 画板 1.jpg 3.3 Leaf ↔ Spine (Level B) The Leaf-to-Spine links form the aggregation layer of the fat-tree topology, carrying traffic between different rail groups and ensuring non-blocking communication across the entire GPU cluster. These switch-to-switch connections demand higher data rates to handle aggregated traffic. In 400G NDR InfiniBand fabrics, Leaf-Spine links often operate at 800G by leveraging dual 400G ports. The transceiver modules used at this level are typically OSFP- or QSFP-DD-form-factor on both ends, as they support 800G transmission. The cabling infrastructure for Level B is predominantly multi-mode fiber with MTP®/MPO connectors (e.g., 2xMTP®/MPO-12 APC) designed for parallel optics. 画板 1 拷贝.jpg 3.4 Spine ↔ Core (Level C) The Spine-to-Core links represent the highest aggregation level within the DGX SuperPOD fabric, connecting multiple SUs or interfacing with the broader data center network, including storage and management infrastructures. This layer is critical for scaling the cluster beyond a single SU and for handling north-south traffic such as checkpointing and dataset ingestion. Like Level B, these links typically operate at 800G rates using OSFP or QSFP-DD transceivers. The physical infrastructure relies heavily on cluster cabling, with main trunk cables running long distances across different areas of the data center, using advanced connector types such as MPO-8/12 APC to support high-speed parallel transmission. This cluster approach ensures manageable, scalable, and upgradeable connectivity for the core network layer. 画板 1 拷贝 2.jpg Connectivity Components 4.1 MTP®/MPO Fiber Cables NVIDIA Protocol Compatibility: Seamlessly supports InfiniBand, Ethernet, and NVLink protocols, enabling flexible deployment across NVIDIA-based AI clusters without infrastructure replacement.
