What Ethernet speeds does the HPE P42044-B21 adapter support?

The HPE P42044-B21, Mellanox MCX631102AS-ADAT adapter, is described as an Ethernet 10/25Gb solution. It supports both 10Gb and 25Gb Ethernet operation, allowing it to function in networks that use either speed. This dual-speed capability is useful for environments migrating from 10Gb to 25Gb while maintaining a consistent adapter type.

How many network ports are available on the P42044-B21 adapter?

The P42044-B21 adapter provides two Ethernet ports. It is defined as a 10/25Gb, 2-port SFP28 Ethernet adapter. These dual SFP28 ports enable configurations that require multiple network connections from a single adapter, such as redundant paths or increased aggregate bandwidth.

What interface type is used on the HPE Mellanox MCX631102AS-ADAT adapter?

This adapter uses SFP28 interfaces for its two Ethernet ports. It is categorized as a 10/25Gb, 2-port SFP28 Ethernet adapter, which means each port uses the SFP28 form factor for 10Gb or 25Gb Ethernet connectivity. This allows use with compatible SFP28 transceivers and cabling.

How is the P42044-B21 positioned within product categories?

The P42044-B21 is categorized as a network adapter, specifically an Ethernet adapter in the 10/25Gb, 2-port SFP28 class. It is also identified as an enterprise product level component. These categorizations help align it with data center and core networking requirements rather than entry-level use.

What is the model name associated with SKU P42044-B21?

SKU P42044-B21 corresponds to the Mellanox MCX631102AS-ADAT Ethernet 10/25Gb 2-port SFP28 Adapter for HPE. This model name helps ensure correct identification and matching with documentation, configuration guides, and internal hardware standards during procurement and deployment.
