What This Is NOT

NOT InfiniBand. ConnectX-4 EN is Ethernet-only — no VPI, no IB mode.
NOT ConnectX-5, ConnectX-6, or newer. ConnectX-4 generation — no PCIe 4.0, no 200GbE per port.
NOT a standard NVIDIA retail card. Dell OEM firmware — feature parity in non-Dell servers is not guaranteed.
NOT supplied with QSFP28 transceivers, DAC/AOC cables, or bracket accessories.

Compatibility

Validated platform: Dell PowerEdge servers with a PCIe 3.0 x16 (or PCIe 4.0/5.0 backward-compatible) slot.
Cabling: QSFP28 DAC (passive copper, ≤ 5 m), QSFP28 AOC (active optical), or QSFP28 optical transceiver with MMF/SMF — sold separately.
Switch pairing: any 100GbE Ethernet switch with QSFP28 ports — for example NVIDIA Spectrum / Spectrum-2, Cisco Nexus 9000, Arista 7000-series, Dell EMC PowerSwitch S/Z-series.
Backward compatibility: QSFP28 cages accept QSFP+ 40G modules (port auto-negotiates to 40GbE).
OS support: RHEL, SLES, Ubuntu, Windows Server, VMware ESXi — use Dell-signed mlx5 drivers from Dell Support.

Frequently Asked Questions (FAQ)
Q. What is the Dell 0NHYP5?
The Dell 0NHYP5 is a Dell OEM Mellanox ConnectX-4 EN dual-port 100GbE QSFP28 network adapter, PCIe 3.0 x16, qualified for Dell PowerEdge servers.
Q. Is 0NHYP5 InfiniBand-capable?
No. ConnectX-4 EN is Ethernet only — no VPI, no IB mode.
Q. What is the NVIDIA Mellanox equivalent of 0NHYP5?
It corresponds to the MCX416A-CCAT family (ConnectX-4 EN dual-port 100GbE QSFP28), with Dell-specific OEM firmware.
Q. Can the 0NHYP5 be used in non-Dell servers?
Physically yes, but Dell OEM firmware may restrict features or refuse to load mlx5 drivers in non-Dell BIOS environments. Verify before deploying.
Q. Does the 0NHYP5 support RoCE and NVMe-oF?
Yes — RoCE v1/v2 and NVMe-oF (target and initiator) are supported in hardware on the ConnectX-4 EN ASIC.
