Frequently Asked Questions

What types of cables are compatible with this network card?

The MCX556A-ECAT supports standard QSFP28 direct attach copper cables, active optical cables, and optical transceivers for both short-reach and long-reach applications.

Can this NIC card operate in both InfiniBand and Ethernet modes simultaneously?

Yes, each port can be configured independently for either InfiniBand or Ethernet operation, providing flexibility in mixed-environment deployments.

What virtualization features does this network adapter support?

The card supports SR-IOV (Single Root I/O Virtualization) with up to 512 virtual functions, allowing direct assignment of virtual NICs to virtual machines for near-native performance.

Is this network card compatible with PCIe Gen4 systems?

While the MCX556A-ECAT is designed for PCIe Gen3, it is backward compatible with PCIe Gen4 systems but will operate at Gen3 speeds. For native Gen4 support, consider the MCX556A-EDAT model.
