Tech Seller USA supplies genuine Mellanox and NVIDIA Networking hardware - ConnectX network adapters, InfiniBand and Ethernet switches, and DAC and AOC cables for high-performance computing, AI clusters and low-latency data centre fabrics.
InfiniBand vs High-Speed Ethernet
Mellanox is the reference platform for both. InfiniBand delivers the lowest achievable latency and native RDMA, which is why it dominates HPC clusters and large-scale AI training fabrics. High-speed Ethernet with RoCE offers most of the throughput benefit while staying on standard Ethernet infrastructure, which is usually the easier path for enterprise data centres. ConnectX adapters support both, so the fabric decision can be made at the switch layer.
Adapters, Optics and Cabling
At 25G, 100G and above, the cable and transceiver choice matters as much as the adapter. Direct-attach copper is cost-effective in-rack, while active optical cables cover longer runs. Mismatched or uncoded optics are the most common cause of links that will not come up. Browse all networking hardware or contact us with your fabric requirement.
