Supporting AI, HPC and GPU Cluster Deployments

AI infrastructure places extreme pressure on the network. GPU clusters need high-speed, low-latency connectivity between servers, switches, storage and external networks. If the interconnect layer is not correctly specified, expensive compute resources can be left underutilised.

Gbics can support AI and HPC projects by helping customers source compatible connectivity for:

  • GPU server clusters

  • AI training environments

  • AI inference infrastructure

  • High-performance storage fabrics

  • RoCE Ethernet networks

  • InfiniBand fabrics

  • Leaf-spine data centre networks

  • Switch uplinks and scale-out connections

  • 400G and 800G migration projects

400G and 800G NVIDIA-Compatible Connectivity

As AI and HPC environments grow, many organisations are moving beyond 100G and 200G into 400G and 800G network infrastructure. These speeds are increasingly important for GPU-dense clusters, modern data centres and high-performance fabrics.
