GB200 optical module interface

The expansion interface uses OSFP optical modules, which can support 16 differential signal lines, allowing a single OSFP to support 4 NVLINK Ports. Typically, the NVLink 5 bandwidth of a single GB200 is 1. However, on NVLink Switches or IB/Ethernet switches and network cards, Mellanox's perspective calculates it in terms of network bandwidth, usually in. The B200 has 18 sub-links, resulting in a bandwidth of 100GB/s * 18 = 1. 8TB/s, which is equivalent to 9 single-direction 400Gbps interfaces from a network perspective. For the sake of clarity, we. The NVIDIA DGX GB Rack Scale Systems User Guide is also available as a PDF. Each rack is an NVL72 rack (72-GPU NVL domain). The guide applies to. NVIDIA GB200, as the next-generation computing platform, derives its core competitiveness not only from its powerful computing units but also from the global interconnection architecture built by NVLink 5.
