AI network switches for sale
How much does a 100G AI network switch cost?
Where a switch is a fixed-configuration catalog part we list the asking price on its product page — the NVIDIA MSN4600-CS2RC is priced there directly. Anything configured to order is quoted on request, since the figure then depends on port count, speed, and optics. Send your fabric requirement and we will return pricing and availability.
What port speeds are available?
The NVIDIA Spectrum-3 SN4600C (MSN4600-CS2RC) carries 64 QSFP28 ports at 100GbE, breaking out to 10, 25, 40, and 50G, which makes it a spine and super-spine platform. The TORswitch is a 32-port 100G Ethernet switch from a 100G–800G family, so that line scales from 100G access up to 800G spine as an AI cluster grows. Exact configuration is confirmed at quote.
What is an AI-fabric switch used for?
It is the low-latency interconnect that ties GPU nodes and disaggregated-memory appliances into one cluster — the east-west fabric that carries training, inference, and RDMA memory traffic. The TORswitch is optimized for AI, storage, and cloud networking.
Is the TORswitch new hardware?
Yes — it is a new, open, enterprise-ready switch. Exact configuration is confirmed at quote.
