NVIDIA H200 NVL 4-Way NVLink Bridge

Overview

The 4-way NVLink bridge is what turns four discrete H200 NVL PCIe cards into a single NVLink domain — up to 1.8 TB/s across the group and 564 GB of combined HBM3e, addressable as one pool. It is a passive board: no power, no firmware, no management, which is the point. Bridging four cards directly avoids the NVLink switches a comparable topology would otherwise need, taking cost and power out of the node. This is an accessory rather than a standalone product, and it is only useful with H200 NVL cards in a chassis whose slot spacing and riser layout accept it — a server that physically fits four dual-wide cards will not necessarily bridge them. Confirm slot pitch against your chassis before ordering; the exact bridge configuration your node requires is confirmed at quote.
