RoCE (RDMA over Converged Ethernet) enables direct memory access between servers without CPU involvement, significantly reducing latency and CPU utilization. This NIC card implements both RoCE v1 and v2, providing low-latency performance for distributed applications and storage systems.
SR-IOV allows direct assignment of adapter resources to virtual machines, bypassing the hypervisor for network operations. This network interface card supports up to 256 virtual functions, enabling near-native performance for virtualized workloads while maintaining security isolation between tenants.
The MCX4121A-ACAT supports various SFP28 transceivers and direct attach copper cables for 25GbE, 10GbE, and 1GbE connections. For optimal performance, use Mellanox-certified cables and transceivers that have been validated for compatibility with this specific network card model.
