The NVIDIA MCX512A-ACUT ConnectX-5 Network Adapter operates over PCIe 3.0 x8, delivering high-bandwidth host connectivity for demanding enterprise environments. This dual-port SFP28 network interface card supports both 10GbE and 25GbE Ethernet speeds, making it ideal for data centers requiring flexible, scalable network infrastructure. Built on NVIDIA's ConnectX-5 architecture, the MCX512A-ACUT combines performance with intelligent offload capabilities to reduce CPU overhead and improve application throughput.

Network engineers and IT infrastructure teams will appreciate the advanced feature set embedded in this adapter. RDMA support for both RoCE v1 and RoCE v2 enables low-latency, high-throughput communication essential for high-performance computing and storage workloads. The card supports up to 256 Virtual Functions (SR-IOV) per port for cloud and virtualization deployments, while hardware offload engines handle ASAP² OVS offload, VXLAN stateless offload, and NVGRE stateless offload to maximize efficiency. IEEE 1588 PTP hardware timestamping ensures precise synchronization for latency-sensitive applications. The low-profile form factor with included LP bracket fits space-constrained chassis, with an optional full-height bracket for flexibility. Congestion control via hardware-based DCB/PFC and ECN protects data center fabric integrity. Operating across 0°C to 55°C, the MCX512A-ACUT maintains reliability in varied deployment conditions and complies with RoHS standards. NVIDIA's broad OS support spans Linux (OFED), Windows Server, and VMware ESXi.

Enterprise Deployment Scenarios

• High-performance computing clusters requiring low-latency RDMA communication
• Software-defined networking environments leveraging VXLAN and NVGRE overlay offload
• Virtualized data centers using SR-IOV for tenant isolation and multi-tenant cloud platforms
• Storage area networks and NAS systems requiring 25GbE throughput with precise time synchronization
• Hybrid cloud infrastructure spanning on-premises and cloud-native workloads across multiple operating systems
