Buying guide
AI cluster performance lives and dies by the interconnect. SYNDROME AG stocks the NVIDIA networking line that pairs with our GPU inventory: ConnectX-7 and ConnectX-8 adapters, BlueField-3 DPUs, Quantum-2 QM9700 and next-gen Quantum-X800 InfiniBand switches, and Spectrum-X Ethernet for RoCE fabrics.
Optics and cabling — 800G OSFP, 1.6T OSFP-XD, DAC and AOC assemblies — ship from the same warehouse, so a cluster order leaves as one consignment with matched firmware notes. Fabric design help is available through the Solutions team.
Yes — tell us GPU count and topology preference (fat-tree, rail-optimized) and we compose switches, NICs and optics with firmware compatibility checked.
Both: NVIDIA-branded for full support contracts and qualified third-party for cost-optimized builds — clearly labeled per SKU.
Hardware ships with base firmware; NVIDIA support contracts can be arranged through our partners on request.
