FAQ
Ask a QuestionFind answers to common questions about our products.
How is the B3140H BlueField-3 SuperNIC different from a standard 400G NIC?
The B3140H is designed for AI and high-performance data center networking, not just basic packet forwarding. With BlueField-3 architecture, onboard Arm cores, DDR memory, and advanced acceleration features, it can offload more networking and management tasks from the host server.
Does this SuperNIC support both 400GbE and NDR InfiniBand?
Yes. This model supports 400GbE as the default mode and can also be used for NDR InfiniBand when the server, switch, cable, firmware, and software stack are configured for IB networking.
What type of cable or transceiver should be used with this card?
The card uses a single QSFP112 port, so the cable or optical module should match the target link mode, such as 400GbE or NDR InfiniBand.
What does “Crypto Disabled” mean for this model?
“Crypto Disabled” means this version does not enable certain cryptographic acceleration functions. It is suitable for customers who need high-speed networking and offload capabilities but do not require crypto acceleration on the adapter.
