DUAL-PORT FABRIC FLEXIBILITY: Mellanox ConnectX-3 VPI (MCX354A-FCBT) runs 56Gb/s FDR InfiniBand or 40GbE per QSFP+ port two independent fabrics or one bonded 80GbE link from a single card.
1µS-CLASS LATENCY: PCIe 3.0 x8 with hardware RDMA (InfiniBand native + RoCE) moves data node-to-node without CPU copies, cutting MPI and storage job completion times.
SCALE-OUT STORAGE & HPC: Dual ports let one server attach to two fabric legs ideal for Ceph/GPFS/Lustre storage nodes and compute nodes needing redundant fabric paths.
CPU-OFFLOAD ARCHITECTURE: Hardware I/O virtualization, QoS, congestion control and GPU communication offloading free the host processor for actual compute work.
ENTERPRISE DEPLOYMENT KIT: PXE/UEFI boot, energy-efficient operation, Linux/Windows/VMware support, plus low-profile and full-height brackets for any chassis.

Two QSFP+ ports, two protocols, one proven controller. The GLOTRENDS ST7384 builds on the Mellanox ConnectX-3 VPI (MCX354A-FCBT) each port independently runs 56Gb/s FDR InfiniBand or 40GbE Ethernet. Attach one server to an IB compute fabric and a 40GbE storage fabric simultaneously, or bond both ports for 80GbE aggregate. Latency as low as 1µs and hardware RDMA (native InfiniBand plus RoCE) make this the workhorse for scale-out clusters: MPI jobs exchange data without CPU copies, Ceph and Lustre nodes push full-bandwidth streams, and VM migration between hosts finishes in seconds rather than minutes. Hardware QoS and congestion control keep the fabric predictable when many nodes contend for bandwidth. Who buys this card: research labs and universities maintaining FDR-era IB clusters, hosting providers running 40G storage backends, and integrators who need PN-verified spares for existing Mellanox deployments. Specifications: 2x QSFP+ (FDR IB / 40GbE per port) | PCIe 3.0 x8 | InfiniBand RDMA + RoCE | SR-IOV, QoS, congestion control | PXE/UEFI boot | Aluminum heat sink; low-profile + full-height brackets included. Compatibility: Linux via MLNX_OFED, Windows via WinOF, VMware ESXi. Use FDR-rated QSFP+ DAC/AOC or 40G-SR4 optics. Supported by the worldwide Mellanox user community with mature, long-available drivers.
