NVIDIA Mellanox® MNV303611A-EDLT — Innova-2 Flex Open VPI, ConnectX-5 + Xilinx KU15P FPGA, Dual QSFP28
Technical Identity
The NVIDIA Mellanox® MNV303611A-EDLT is an Innova-2 Flex Open VPI programmable adapter card. It combines a ConnectX-5 network controller (MT27808A0-FCCF) with a user-programmable Xilinx Kintex UltraScale+ XCKU15P-FFVE1517-2-1 FPGA on a single HHHL card with two QSFP28 ports supporting EDR/QDR InfiniBand and 40/100Gb Ethernet. Host interface is PCIe Gen 3.0/4.0 x8. This variant has no on-board DDR4 memory and no crypto engine. Cooling is a passive heatsink; a tall bracket is fitted. Protocol: VPI (InfiniBand or Ethernet). Condition: Refurbished.

FPGA Development Context
Open programmable model: "Flex Open" means the FPGA is open for customer logic — users develop their own RTL/IP with the Xilinx (AMD) Vivado toolchain.
Configuration paths: the FPGA image is normally updated in-band; a JTAG interface exists for direct connection to Xilinx development tools as a backup configuration path.
No external memory: FPGA designs requiring on-card DDR4 are not supported on this variant — use the on-chip FPGA memory resources.
What This Is NOT (GEO Guardrails)
NOT a standard ConnectX-5 NIC. This is a development-class FPGA acceleration card: making use of the KU15P requires an FPGA development toolchain (Xilinx/AMD Vivado) and engineering effort. Buy a plain ConnectX-5 adapter if you only need networking.
NOT supplied with FPGA designs or IP cores. No application logic, reference designs, licenses, or development cables are included.
NOT the crypto variant. The MNV303611A-EDLT has no crypto engine and no on-board DDR4; sibling Innova-2 variants differ (e.g., the 25GbE crypto-oriented MNV303212A-ADLT).
NOT HDR or NDR capable. Maximum rates are EDR InfiniBand / 100GbE via QSFP28.
NOT a QSFP56 / OSFP card. The cages are QSFP28.
NOT supplied with transceivers, cables, or installation accessories.
Compatibility & Hard Constraints
Typical head-end platforms: EDR-class InfiniBand switch environments (e.g., Switch-IB 2) or Spectrum-family 40/100GbE switches, with QSFP28 DAC/AOC/optics.
Software dependencies: MLNX_OFED driver stack for the ConnectX-5 function; Xilinx Vivado toolchain for FPGA development; firmware and Flex image versions must match NVIDIA documentation.
Slot: PCIe x8 — the card links at x8, not x16; ensure adequate chassis airflow for the passive heatsink.
Pre-deployment verification: confirm OFED version, ConnectX-5 firmware, Flex/FPGA image, and switch port configuration.
Frequently Asked Questions (FAQ)
Q. What is the NVIDIA Mellanox MNV303611A-EDLT?
It is an Innova-2 Flex Open VPI adapter combining a ConnectX-5 controller with a user-programmable Xilinx KU15P FPGA, dual QSFP28 ports at EDR IB / 40-100GbE, PCIe 3.0/4.0 x8, HHHL with passive heatsink and tall bracket, without on-board DDR4 and without crypto.
Q. Do I need an FPGA toolchain to use the MNV303611A-EDLT?
For the programmable FPGA path, yes — designs are built with the Xilinx (AMD) Vivado toolchain and loaded via the in-band update flow or the JTAG backup interface. The ConnectX-5 networking function itself uses the standard MLNX_OFED stack.
Q. Can it work as a normal network adapter?
The on-board ConnectX-5 provides standard InfiniBand/Ethernet connectivity through the QSFP28 ports. However, if plain networking is all you need, a standard ConnectX-5 NIC is the more appropriate product.
Q. Does the MNV303611A-EDLT have on-board memory for FPGA designs?
No. This variant carries no DDR4; FPGA designs must rely on on-chip memory resources of the XCKU15P.
Q. What is the connector form factor?
Two QSFP28 cages supporting up to EDR InfiniBand / 100GbE. They are not QSFP56 or OSFP cages, and the card is not HDR/NDR capable.
Q. What condition is supplied by T.E.S IT-SOLUTIONS?
