AI Server and HPC Applications

该 MCX556A-ECAT ConnectX-5 100GbE Dual-Port QSFP28 NIC can be deployed in AI training clusters, GPU computing systems, HPC environments, enterprise storage platforms, and high-performance data center networks.

Its support for both 100GbE Ethernet and EDR InfiniBand gives system integrators greater flexibility when designing AI and HPC infrastructure. InfiniBand can be used for high-performance compute fabrics, while Ethernet connectivity can support general data center, storage, and cloud networking requirements.

Data Center Networking Applications

The adapter is suitable for:

• AI training and inference clusters

• GPU server interconnects

• 高性能计算系统

• 企业数据中心

• High-speed storage networks

• Private and public cloud platforms

• 虚拟化环境

• Server network upgrades

• Low-latency cluster networking

该 MCX556A-ECAT ConnectX-5 100GbE Dual-Port QSFP28 NIC provides a flexible option for customers upgrading from lower-speed 10GbE, 25GbE, or 40GbE environments to higher-bandwidth 100GbE or EDR InfiniBand infrastructure.

PCIe Bandwidth Consideration

MCX556A-ECAT uses a PCIe 3.0 x16 host interface. Although both QSFP28 ports can support up to 100Gb/s network speeds, the PCIe 3.0 x16 host interface cannot provide a full 200Gb/s aggregate host bandwidth when both ports operate at maximum speed simultaneously.

For high-performance AI or HPC deployments, server architecture, PCIe bandwidth, workload type, and network topology should be reviewed before configuration.
