FAQ
Ask a QuestionFind answers to common questions about our products.
Is MCX715105AS-WEAT an InfiniBand card or an Ethernet card?
It is a VPI adapter, so the same QSFP112 port can be configured for InfiniBand or Ethernet. NVIDIA lists it as supporting NDR InfiniBand and 400GbE, with Ethernet as the default mode.
Can the single QSFP112 port run NDR InfiniBand and 400GbE at the same time?
No. The port supports both protocols, but it must operate in one link type at a time. Choose InfiniBand for NDR fabric deployments or Ethernet for 400GbE/RoCE networks.
Can I use this adapter in a PCIe Gen4 or Gen3 server?
Yes, but with performance considerations. NVIDIA lists the interface as PCIe Gen5/Gen4 x16 and Gen3 compatible; for full 400G bandwidth, a PCIe Gen5 x16 platform is the preferred choice.
Is this card suitable for AI clusters and high-performance RDMA networks?
Yes. It can be used in NDR InfiniBand fabrics or 400GbE Ethernet/RoCE environments, depending on the selected port mode and switch fabric. This makes it suitable for GPU clusters, HPC systems, and high-throughput storage networks.
