P11338‑B21 Gigabit Ethernet Adapter 10Gb 2‑Port 548SFP+ 

The HPE P11338‑B21 is a high-performance dual-port 10 Gigabit Ethernet Adapter designed to bring robust, low-latency 10 GbE connectivity to HPE ProLiant Gen9 and Gen10 servers. Featuring two SFP+ ports and a PCIe 3.0 x8 interface, this network adapter supports hardware offloads, jumbo frames, and virtualization acceleration while minimizing CPU overhead—ideal for virtualization, storage access, data-intensive applications, and converged network infrastructures.

Features

This plug‑in network card supports standard 10 Gigabit Ethernet Adapter protocol (10GBASE‑X), making it compatible with optical SFP+ transceivers for multimode or single-mode fiber. It is built on Intel X710 or 548SFP+ chipset technology with broad driver support and offers features such as RoCE v1/v2, VXLAN, NVGRE, and GENEVE offloads, as well as IEEE 1588 PTP for time-sensitive applications.

Advanced Options

Certified for use in HPE ProLiant DL and ML Gen9/Gen10 platforms, this adapter integrates seamlessly with server firmware and management tools such as HPE iLO and Advanced Power Manager. With support for jumbo frames up to 9,600 bytes, NIC teaming, SR-IOV virtualization, TCP/UDP/IP offloads, and hardware checksum and segmentation, it delivers maximum network throughput while reducing host processor load.
