Is the MCX4732A-BCAT a standard NIC or an FPGA card?

Both. It is an Innova Flex EN programmable adapter combining a ConnectX-4 Ethernet NIC with a Xilinx Kintex UltraScale KU060 FPGA on the same card, sharing the host PCIe Gen 3.0 x8 interface.

Does the MCX4732A-BCAT support crypto offload?

No. This card is the No-Crypto SKU. It does not include hardware crypto acceleration and is not suitable for IPsec or TLS hardware offload.

Is this card new and how is the FPGA programmed?

Yes — this is a new unit from T.E.S IT-SOLUTIONS (https://www.tes-itsolutions.com). The KU060 FPGA is programmed by the customer using Xilinx development tools (Vivado) and the Mellanox Innova SDK; no FPGA workload is preloaded.

NVIDIA Mellanox MCX4732A-BCAT ConnectX-4 Innova Flex EN Programmable Adapter: This is a single-port QSFP+ 10/40GbE programmable network adapter combining a ConnectX-4 EN NIC with a Xilinx Kintex UltraScale KU060 FPGA on the same card. The card uses PCIe Gen 3.0 x8, includes 2GB of on-board memory, and is supplied without crypto acceleration. This is a half-height half-length (HHHL) card with a passive heat sink. This is a brand new unit.

Engineering Context

The Innova Flex platform pairs an Ethernet NIC with a programmable Xilinx FPGA so customers can implement custom in-line packet processing, offload, or acceleration directly on the adapter. The KU060 FPGA exposes its fabric to the host through a PCIe interface alongside the NIC datapath. The MCX4732A-BCAT is a developer-grade adapter targeted at network function development, prototyping, and bespoke offloads — it is not a turnkey crypto or storage offload card. The single QSFP+ port operates at 40GbE or 10GbE (using a QSFP+ to SFP+ adapter or breakout). Tall bracket is fitted for standard server slots.

Deployment & Use Cases

FPGA-accelerated network function virtualization (NFV) prototyping. Custom inline packet inspection, filtering, or telemetry probes. SDN dataplane research and development. Time-stamping or hardware-anchored traffic generators. High-frequency trading research builds. Custom Ethernet offloads where stock NIC firmware is insufficient.

Compatibility & Hard Constraints

Requires a PCIe Gen 3.0 x8 (or wider) host slot. The QSFP+ port is Ethernet-only and does not support InfiniBand. Single-port card — does not support dual-port redundancy on a single adapter. Passive heat sink requires sufficient server airflow; this is a developer/lab adapter and benefits from vendor-validated airflow profiles. Custom FPGA workloads require Xilinx development tooling (e.g., Vivado) and Mellanox Innova SDK; programming the KU060 is the customer's responsibility. Card has no crypto block — not suitable for IPsec or TLS offload. Tall bracket only (no low-profile option included).
