Which Ethernet speeds does the 621SFP28 adapter support?

The HPE Ethernet 10/25Gb 2-port 621SFP28 Adapter, SKU 867328-B21, supports 10Gb and 25Gb Ethernet connectivity. This means it can operate in infrastructures built around 10 Gigabit Ethernet, 25 Gigabit Ethernet, or a mix of both, depending on how the network and switch ports are configured.

How many network ports are available on the HPE 867328-B21 adapter?

The HPE 867328-B21 is described as a 2-port 621SFP28 adapter and as a dual-port 10/25GbE SFP28 adapter. This indicates that the card offers two SFP28-based Ethernet ports, enabling redundant connections, separate network paths, or other dual-link designs in server deployments.

What connector type does the HPE Ethernet 10/25Gb adapter use?

This product is identified as a dual-port 10/25GbE SFP28 adapter, which means it uses SFP28 interfaces for its network ports. SFP28 is commonly used for 10Gb and 25Gb Ethernet connections and determines the type of transceivers or direct-attach cables that can be used with the adapter.

How can I accurately order this specific HPE network adapter?

To order this specific adapter, reference the SKU 867328-B21 and the model description HPE Ethernet 10/25Gb 2-port 621SFP28 Adapter. Using both the SKU and the exact model name helps procurement teams and suppliers match the correct dual-port 10/25GbE SFP28 adapter for your deployment.
