NVIDIA Mellanox MBF1L516A-CSCAT BlueField-1 SmartNIC (NVIDIA P/N: 900-9D1A2-0066-SN1): This is a BlueField-1-class SmartNIC / data processing unit (DPU) combining a ConnectX-class network controller with an integrated ARM-based SoC for offloading networking, storage, and security workloads from the host CPU. It provides 100GbE Ethernet across Dual QSFP28 ports. This is a network adapter with onboard programmable cores; it is not a passive NIC, not a switch, and not an accelerator-only card. Hardware crypto acceleration is enabled on this unit, supporting IPsec/TLS offload pipelines. This is a refurbished unit.
Engineering Context
The MBF1L516A-CSCAT integrates a 16-core ARM, 16GB onboard DDR, and a PCIe Gen3.0/4.0 x16 host interface. The dual Dual QSFP28 interface supports Ethernet. As a BlueField-1 DPU, it can isolate infrastructure functions (overlay networking, NVMe-oF, firewalling, telemetry) on its embedded cores while the host CPU runs application workloads. The card requires a host slot delivering the full PCIe lane width and adequate airflow; the embedded SoC adds thermal load beyond a passive ConnectX adapter.
Deployment & Use Cases
Bare-metal cloud and multi-tenant infrastructure where east-west traffic is offloaded from the hypervisor. NVMe over Fabrics (NVMe-oF) target and initiator acceleration. Software-defined networking with OVS hardware offload, VXLAN/Geneve tunneling, and connection tracking. Inline storage encryption and host-isolated security appliances. Ethernet-only data center fabrics built on Spectrum or compatible 100GbE switching.
