HPE789897-001

Ethernet 1 Gb 4-Port 331FLR FlexibleLOM Network Adapter

The HPE789897-001 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 HPEProLiant 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 HPEProLiant 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 HPESea 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,
