HPE Ethernet 10Gb 2-port 537SFP+ OCP3 Internal Fiber

The HPE Ethernet 10Gb 2-port 537SFP+ OCP3 Internal Fiber adapter provides high-speed 10 GbE connectivity in an OCP3 form factor with a PCI Express host interface and fiber ports. It is designed to deliver low latency and efficient I/O processing by offloading packet handling from the host CPU, making it suitable for data center and enterprise deployments that require reliable wired networking and increased bandwidth.

Advantages

This adapter reduces CPU utilization by offloading packet processing and supports tunnel offloads such as VXLAN and NVGRE. It accelerates packet handling through support for the Data Plane Development Kit (DPDK) and offers single root I/O virtualization (SR-IOV) to improve virtual network performance. The combination of offloads and standards compliance helps lower latency and increase effective I/O bandwidth for workload-intensive applications.

Suitable for

• Data center servers requiring 10 GbE fiber connectivity
• Virtualized environments using SR-IOV
• High-throughput applications and storage networks
• Deployments using VXLAN or NVGRE tunneling

How to use

Install the adapter into a compatible server PCI Express slot following the server manufacturer’s installation procedures for OCP3 cards. Connect SFP+ fiber transceivers and fiber cabling to the card’s ports. Ensure the host BIOS/firmware and operating system have the appropriate HPE drivers and firmware updates installed, and configure network settings, virtualization options (SR-IOV) and tunnel offloads (VXLAN/NVGRE) as required by your environment.

Recommendations

Use certified SFP+ transceivers and proper fiber cabling for 10 GbE links, keep firmware and drivers up to date, and enable offload and DPDK features where supported to minimize CPU usage and achieve low-latency, high-throughput performance.
