How many network ports does the HPE P41970-001 adapter provide?

The HPE P41970-001 adapter provides four Ethernet ports. These are 10/25Gb-capable SFP28 ports, allowing multiple network links from a single adapter. The four-port configuration is useful for link aggregation, segregating network traffic, or connecting to different switches in a server environment.

What Ethernet speeds are supported by the BCM57504 4-port SFP28 adapter?

The Broadcom BCM57504 Ethernet 4-port SFP28 adapter associated with P41970-001 supports 10Gb and 25Gb Ethernet operation on each port. This 10/25Gb capability gives flexibility to connect to either 10GbE or 25GbE switches and to adapt as network infrastructure evolves to higher speeds.

What type of network interface is used on the P41970-001 adapter?

The P41970-001 adapter uses SFP28 interfaces on all four Ethernet ports. SFP28 is designed for 10 or 25Gb Ethernet, enabling the use of compatible SFP28 optical transceivers or direct-attach cables that match the selected speed and cabling standards in the data center.

How is the HPE Broadcom BCM57504 adapter categorized for deployment planning?

This product is categorized as a network adapter and specifically as a PCI Express Ethernet adapter with four 10/25Gb SFP28 ports. That classification helps planners ensure there are suitable PCIe expansion slots available in target servers and confirms that it is intended for Ethernet connectivity at 10 and 25Gb speeds.

Product overview

The HPE Broadcom BCM57504 Ethernet 10/25Gb 4-port SFP28 Adapter P41970-001 is a network adapter designed for environments that require flexible 10 or 25Gb Ethernet connectivity. Built around the Broadcom BCM57504 controller architecture, it provides four SFP28 ports that can operate at 10Gb or 25Gb speeds, supporting a range of modern Ethernet infrastructures. As a PCI Express solution, it is suitable for servers that need high-bandwidth network interfaces over a PCIe host connection. The four-port SFP28 design allows consolidation of multiple network links on a single adapter, simplifying cabling and slot planning. Using 10/25Gb-capable SFP28 interfaces, IT teams can align this adapter with existing optical or copper direct-attach cabling that matches SFP28 form factor and speeds. This adapter supports data center, virtualization, and high-throughput workloads that rely on 10Gb or 25Gb Ethernet.
