What Ethernet speeds does the HPE P53862-B21 adapter support?

The HPE P53862-B21 Broadcom BCM57414 Ethernet adapter supports 10Gb and 25Gb Ethernet connectivity. It is categorized as a 10/25Gb Ethernet adapter, allowing deployment at either speed depending on network design and compatible SFP28 modules or cables. This helps align server connectivity with modern 10GbE or 25GbE switch infrastructures.

How many network ports are available on the HPE P53862-B21 adapter?

: "The adapter provides two SFP28 network ports as indicated by its description as a 2-port SFP28 adapter. Each port can be used for 10Gb or 25Gb Ethernet connectivity, enabling link redundancy, aggregation, or separate traffic paths from a single PCIe 3.0 x8 network interface card in an HPE server.

What host interface does the HPE P53862-B21 network adapter use?

This adapter belongs to the PCIe 3.0 x8 10/25Gb Ethernet adapter category. That means it connects to the server through a PCI Express 3.0 x8 slot. Ensuring that target HPE ProLiant or Apollo servers have available PCIe 3.0 x8 slots is important for proper installation and to provide sufficient bandwidth for the two 10/25Gb ports.

For which server families is the HPE P53862-B21 intended?

The adapter is categorized as a dual-port SFP28 10/25GbE solution for HPE ProLiant and Apollo servers. This indicates it is targeted at these HPE server families, simplifying integration and qualification when standardizing network adapters across ProLiant and Apollo platforms in enterprise environments.

What type of connector does the HPE P53862-B21 use for network links?

The adapter is described as a 2-port SFP28 adapter, which means each network interface uses an SFP28 cage. These cages are intended for compatible SFP28 transceivers or direct attach cables that support 10Gb or 25Gb Ethernet, giving flexibility in choosing optical or copper connectivity within supported distances.
