HPEP11586-001

Marvell QL41132HQCU Dual-Port 10 Gb SFP+ OCP3 Gigabit Ethernet Adapter

The HPEP11586-001 is a high-performance Marvell QL41132HQCU dual-port 10 GbE SFP+ Gigabit Ethernet Adapterengineered in the OCP 3.0 format for HPEGen10 Plus servers. Offering full line-rate 10 Gbps throughput on both ports, it provides ultra-reliable fiber connectivity for virtualization, storage, and high-density compute workloads. Integrated RDMA support and tunneling offloads minimize CPU usage, while secure firmware validation ensures trusted deployment in enterprise infrastructures. Easy to install with OCP mezzanine flexibility, it's designed to future-proof evolving network environments.

Features

Built for efficiency and density, this adapter utilizes a PCIe Gen3 ×8 interface within the OCP 3.0 architecture. It supports dual 10 Gb/s data streams via SFP+ ports, offering both short-range and long-range fiber optic options. Advanced hardware offload support includes RDMA (RoCE, iWARP) and tunnel encapsulations (VXLAN, GRE, NVGRE), enabling optimized performance in virtualized and clustered environments. The adapter features a root-of-trust boot process that authenticates firmware×protecting against unauthorized modifications and enhancing infrastructure security. Compatible with HPEProLiant Gen10 Plus servers, this module combines high throughput with smart security and low latency.

Advanced Options

Engineered for dependable enterprise networking, the adapter delivers full-duplex 10 Gb throughput on both ports consistently with minimal latency. Advanced offload capabilities reduce host CPU usage, improving performance in high-density or virtualized deployments.
