Lenovo 4X67A97322 Thinksystem NVIDIA 4-WAY Bridge for H200 NVL - 4X67A97322

Lenovo 4X67A97322 ThinkSystem NVIDIA 4-Way NVLink Bridge for H200 NVL

Overview

The Lenovo 4X67A97322 is the NVIDIA 4-Way NVLink Bridge designed for ThinkSystem servers paired with NVIDIA H200 NVL GPUs. When you are building a multi-GPU compute node for AI training, high-performance inference, or large-scale simulation workloads, the NVLink bridge is not optional — it is the physical interconnect that allows up to four H200 NVL accelerators to operate as a unified memory pool rather than discrete, bandwidth-limited devices. Without this component, GPU-to-GPU communication is routed over PCIe, which becomes the bottleneck in any collective communication-heavy workload. The 4X67A97322 is the Lenovo-qualified part for this configuration, sourced to match the mechanical and electrical requirements of the H200 NVL form factor.

Key Features

• 4-Way GPU Interconnect: Bridges up to four NVIDIA H200 NVL accelerators in a single ThinkSystem node, enabling GPU-to-GPU memory access and data transfers at NVLink bandwidth — critical for distributed training jobs where PCIe bottlenecks would otherwise stall gradient synchronization.
• H200 NVL Compatibility: Engineered specifically for the H200 NVL mechanical footprint. Using a mismatched bridge from a prior GPU generation risks physical incompatibility or degraded link negotiation — this part eliminates that variable.
• Factory-New Genuine Component: Sourced as a factory-new Lenovo part (MPN 4X67A97322), ensuring it meets the fit and finish specifications of the ThinkSystem platform without grey-market risk.
• Manufactured in Mexico: Country of origin MX, consistent with Lenovo ThinkSystem accessory production for the North American market.

Integration & Compatibility

The 4X67A97322 is designed for deployment in Lenovo ThinkSystem servers that support NVIDIA H200 NVL GPU configurations. Before ordering, confirm your specific server model's GPU cage and bridge slot geometry against Lenovo's ThinkSystem compatibility matrix — H200 NVL bridge geometry differs from prior H100 SXM or PCIe form factors. This bridge is a platform-specific component; verify the target system's service guide lists 4X67A97322 as the supported bridge option. For broader Lenovo ThinkSystem compute options or GPU accelerator configurations, review the full server accessory catalog. If you are planning a multi-node AI compute cluster, also evaluate your high-speed networking requirements alongside GPU interconnect — NVLink handles intra-node; InfiniBand or Ethernet handles inter-node.

Frequently Asked Questions

Q: What GPU does the 4X67A97322 bridge support?

A: The 4X67A97322 is the Lenovo ThinkSystem NVIDIA 4-Way Bridge designed for H200 NVL GPU configurations. It is not a universal NVLink bridge — confirm your server and GPU combination against Lenovo's compatibility documentation before ordering.

Q: How many GPUs does this bridge connect?

A: This is a 4-way bridge, enabling up to four NVIDIA H200 NVL accelerators to be interconnected via NVLink within a single ThinkSystem server node.

Q: Is the 4X67A97322 compatible with H100 GPUs?

A: The 4X67A97322 is specified for H200 NVL. H100 SXM and H100 NVL variants use different bridge geometries — do not assume cross-generation compatibility without consulting Lenovo's service guide for your specific system.

Q: What does this bridge weigh?

A: The 4X67A97322 ships at 10 lb (packaged weight per distribution data).

Q: Where is the 4X67A97322 manufactured?

A: Country of origin is Mexico (MX), consistent with Lenovo ThinkSystem accessory production.

Marty Allison

The Lenovo 4X67A97322 is a platform-specific NVLink bridge — not a generic GPU accessory you can swap across generations. If you are commissioning a 4-way H200 NVL node in a ThinkSystem chassis, this is the part that determines whether your GPUs operate as a unified accelerator pool or as bandwidth-constrained islands talking over PCIe.

Technical Highlights:

• 4-Way NVLink Configuration: Connects four H200 NVL GPUs into a single high-bandwidth fabric — the difference between collective operations running at NVLink speeds versus being throttled by PCIe gen5 x16 limits per GPU slot.
• H200 NVL-Specific Geometry: The H200 NVL bridge slot is not backward-compatible with H100 bridge hardware. Ordering 4X67A97322 specifically avoids the fit and link-negotiation failures that come from substituting a prior-generation part.
• Packaged Weight 10 lb: At 10 lb packaged, factor handling logistics if installing in a rack that is already partially populated — the bridge itself is not heavy, but combined GPU and bridge installation in a dense ThinkSystem chassis benefits from a second technician.

Deployment Considerations:

• Verify 4X67A97322 is listed in your specific ThinkSystem server's service guide before procurement — Lenovo's H200 NVL platform spans multiple chassis variants, and bridge compatibility is chassis-dependent, not just GPU-dependent.
• Detailed NVLink bandwidth specifications and thermal requirements for this bridge are not published in standard distribution data — pull Lenovo's ThinkSystem service guide for your server model to confirm power envelope and installation torque specs before commissioning.

Best fit for enterprise AI infrastructure teams standing up 4-way H200 NVL nodes in Lenovo ThinkSystem servers, where platform-matched components are required to maintain system warranty and performance guarantees.
