HPE Ethernet 10/25Gb 2-port 640SFP28 Internal Ethernet Fiber 25000 Mbit/s

Ethernet 10/25Gb 2-port 640SFP28 adapter in a PCIe card form factor provides two SFP28 ports supporting 10GbE and 25GbE connections. The card offers up to 50 Gbps bi-directional per port and a theoretical aggregate bi-directional bandwidth of 100 Gb/s. It is designed for installation in a server or workstation with a compatible PCIe slot.

Advantages

This 2-port 640SFP28 adapter delivers high-density, low-latency Ethernet connectivity in a standard PCIe card form factor. Support for SFP28 modules enables flexible use of copper or optical transceivers and simplifies upgrades from 10GbE to 25GbE. The adapter’s dual-port design and high aggregate bandwidth suit virtualization, storage networking and high-throughput applications while keeping a simple physical footprint.

Key specifications

• Interface: Two SFP28 ports (each supports 10GbE and 25GbE)
• Per-port throughput: Up to 50 Gbps bi-directional (theoretical)
• Aggregate throughput: Up to 100 Gb/s bi-directional (theoretical)
• Form factor: PCIe card
• PCIe requirement: One x8 PCIe (Gen 8) slot

How to use

Power down the system and insert the adapter into an available x8 PCIe (Gen 8) slot. Secure the card in the chassis and install appropriate SFP28 transceivers or DAC/CR cables for the intended 10GbE or 25GbE connections. Power on the system, install vendor drivers if required, and configure network settings in the operating system or management interface.

Recommendations

Ensure the host system provides an x8 PCIe (Gen 8) slot and adequate cooling. Use compatible SFP28 modules or cables certified for 10GbE/25GbE operation and verify driver support for your operating system before deployment.
