Questions buyers ask about this part
- Will the -6 Dx 100GbE Dual-Port QSFP56 ConnectX fit my server?
- This is a PCIe half-height half-length card on PCIe 4.0 x16. It needs a free slot of that width and electrical lane count — a x16 card in a x8-wired slot will train at half speed, and some platforms reach the card only through a riser that has to be ordered with it. Send us your server model and we will confirm slot availability, riser and bracket height, power connectors and the firmware level before you order — that check is part of every order we ship.
- Is this NVIDIA Networking part genuine, and is the warranty intact?
- Yes. We supply through authorized distribution only, so the part carries the full NVIDIA Networking manufacturer warranty and its firmware update path stays supported. No grey-market stock, no re-labelled drives, no voided warranties.
- Do you offer volume pricing and accept purchase orders?
- The listed price is per unit and indicative; tiered pricing applies at quantity. We accept purchase orders from qualified businesses, government and defence agencies, and educational institutions, with net terms and consolidated invoicing available. Email the quantity you need and we will come back within 48 business hours.
