How many network ports are available on the HPE P42028-001 adapter?

The HPE P42028-001 adapter provides four SFP28 ports. It is defined as a 10/25Gb 4-port SFP28 OCP3 adapter, meaning there are four physical SFP28 interfaces available on the card for Ethernet connectivity at 10Gb or 25Gb speeds, subject to compatible optics or cables.

What form factor does the HPE BCM57504 10/25Gb 4-port adapter use?

This product is specified as a Broadcom BCM57504 Ethernet 10/25Gb 4-port SFP28 OCP3 Adapter for HPE. The OCP3 designation indicates it is an OCP 3.0 network adapter intended for systems that accept that mezzanine form factor, rather than a traditional stand-alone PCIe add-in card.

Which controller is used in the HPE P42028-001 network adapter?

The adapter is based on the Broadcom BCM57504 controller. It is identified as the BCM57504 Ethernet 10/25Gb 4-port SFP28 OCP3 Adapter for HPE, indicating that the BCM57504 is the Ethernet controller providing 10Gb and 25Gb connectivity across the four SFP28 ports on the OCP3 adapter.

Is the HPE P42028-001 adapter suitable for use in HPE environments?

Yes, the product is described as a Broadcom BCM57504 Ethernet 10/25Gb 4-port SFP28 OCP3 Adapter for HPE. This indicates it is intended for HPE environments that support OCP3 adapters, providing four SFP28 ports with 10Gb and 25Gb Ethernet capabilities within compatible HPE server platforms.

Product overview

The HPE BCM57504 Ethernet 10/25Gb 4-Port SFP28 OCP3 Adapter P42028-001 is a network adapter designed to provide flexible Ethernet connectivity at 10Gb or 25Gb speeds. It offers four SFP28 ports, enabling multiple 10Gb Ethernet or 25Gb Ethernet connections from a single adapter. As an OCP 3.0 adapter, it is intended for Open Compute Project mezzanine environments, supporting integration into compatible server platforms. The adapter is based on the Broadcom BCM57504 Ethernet controller, aligning with 10/25Gb network infrastructures and SFP28 optics or direct-attach cabling where supported. With its four-port SFP28 configuration and 10/25Gb capability, this adapter targets workloads that need higher bandwidth and port density within an OCP3 form factor. IT teams can standardize on 10Gb or 25Gb Ethernet while using a consistent adapter model across their environment.
