Overview

One NIC per GPU is the cluster rule of thumb, and CX-7 is that NIC: 400 gig with GPUDirect so tensors skip the CPU entirely. We stock both InfiniBand-first and Ethernet-first firmware profiles.

Current inventory: 65 units across two free-port hubs. Pricing is FOB Singapore / Dubai in USD; volume orders from 10 units receive −5…10%. Serial numbers are recorded for every unit before it leaves the warehouse.

Air and sea freight from Singapore or Dubai under EXW, FOB, CIF or DDP (Incoterms 2020). Export clearance and shipping documents are handled by our hubs. Commercial terms are structured individually for each deal and jurisdiction — your manager will walk you through the options.

New hardware carries a 12-month warranty (refurbished — 6 months). RMA is handled through the nearest hub with advance replacement from stock where available. Serial numbers are recorded for every unit that leaves the warehouse.
