FAQ
Ask a QuestionFind answers to common questions about our products.
Which AICPLIGHT optics or cables should I use with this card?
For short server-to-switch links, 200G QSFP56 DAC or AOC is usually the simplest option. For fiber links, select a 200G QSFP56 optical module that matches the switch port, fiber type, reach, and module power budget. NVIDIA specifies powered connector support for optical and active cables.
Is MCX623105AS-VDAT a single-port 200GbE card or a dual-port 100GbE card?
MCX623105AS-VDAT is a single-port QSFP56 adapter that supports up to 200GbE. If your server design requires two physical 100GbE ports, choose a dual-port CDAT variant instead.
Is this card suitable for RoCE-based storage or AI cluster Ethernet traffic?
Yes. ConnectX-6 Dx supports RoCE for low-latency RDMA over Ethernet and is suitable for storage, virtualization, and high-performance data center workloads when the switch fabric is correctly configured. NVIDIA also lists PeerDirect and storage acceleration features for this adapter family.
