HPE 789897-001

Ethernet 1 Gb 4‑Port 331FLR FlexibleLOM Network Adapter

The HPE 789897‑001 Ethernet 1 Gb 4‑Port 331FLR adapter is a high‑density FlexibleLOM network card deliveringfour full line‑rate Gigabit Ethernet ports through a compact, server‑integrated form factor. Engineered for HPE ProLiant Gen8/Gen9 (and forward‑compatible Gen10) servers, it excels in virtualization, network segmentation, and server consolidation use cases where port density and low power are priorities. Support for VLAN tagging, jumbo frames, TCP/IP offloads, and low‑latency MSI‑X interrupts ensures optimized network traffic without adding to CPU load—making it a robust solution for enterprise-class workloads. With an aggregate throughput of 4 Gb/s and flexibility for future upgrades to 10 GbE, this card offers future‑proof performance and efficiency in space‑constrained IT environments.

Features

Designed for modern server infrastructures, this quad‑port adapter integrates seamlessly into FlexibleLOM slots in HPE ProLiant servers. Utilizing the Broadcom BCM5719 chipset, it supports advanced acceleration features including Large Send/Receive Offload (LSO/TSO), TCP/UDP checksum offload, and VLAN tagging. With support for jumbo frames up to 9 K MTU and PTP timing (IEEE 1588), it's ideal for time‑sensitive and high‑throughput applications. Virtualization‑friendly with NetQueue and VMQ support, it further reduces CPU overhead in multi‑tenant environments. Certified for energy‑efficient operation, it meets IEEE 802.3az standards and optimizes server thermals with HPE Sea of Sensors 3D thermal management.

Advanced Options

Built for enterprise server environments, this adapter provides consistent 1 GbE throughput across all four ports with minimal CPU utilization thanks to its robust offload capabilities. Its Broadcom silicon and support for MSI‑X interrupts ensure stable, efficient processing even under heavy network load. Jumbo frame support and time synchronization (IEEE 1588) enable optimized performance for storage clusters,
