What type of host interface does the HPE 868089-001 use?

: "According to the category information, this adapter is a PCIe 3.0 network adapter. It is intended to be installed in a compatible PCIe 3.0 slot in the host server, allowing the system to access the dual 25GbE SFP28 ports. Buyers should verify available PCIe 3.0 slots on their target platforms.

How many network ports are available on the HPE Mellanox ConnectX-4 Lx EN MCX4421A-ACAN?

The product is described as a dual-port 25GbE SFP28 PCIe network adapter. This indicates there are two Ethernet ports on the card, each designed for 25GbE using SFP28. This dual-port configuration is useful for redundancy, link aggregation, or connecting to separate network segments from the same adapter.

Which connector type is used on this HPE 868089-001 network adapter?

The adapter is specified as a dual-port 25GbE SFP28 PCIe network adapter. The mention of SFP28 indicates that the physical port type is SFP28, which is the common form factor for 25GbE modules and direct-attach copper cables. This allows compatibility with standard 25GbE SFP28 transceivers and cabling.

What controller family does the HPE 868089-001 network adapter belong to?

The model is listed as Mellanox ConnectX-4 Lx EN MCX4421A-ACAN. This places the adapter in the ConnectX-4 Lx EN controller family from Mellanox. Using a defined controller family helps align driver, firmware, and feature expectations across servers that deploy multiple ConnectX-4 Lx EN adapters.
