HPE 665238-001

366FLR 1Gb 4‑Port FlexibleLOM Gigabit Ethernet Adapter

The HPE 665238‑001 (366FLR) is a 1 Gb Gigabit Ethernet Adapter offering four full line‑rate RJ‑45 ports on a FlexibleLOM formfactor, ideal for ProLiant Gen8 and Gen9 rack and scale‑out servers. Powered by the Intel I350 controller, this compact NIC supports high-density networking in virtualized, clustered, or segmented server environments. With support for jumbo frames, advanced offload, and precision time protocol, it delivers balanced performance while reducing CPU overhead and cabling complexity. Perfect for environments requiring multiple LAN interfaces or network segmentation within a single adapter footprint.

Features

Designed for scalable server deployment, this FlexibleLOM adapter interfaces via PCIe 2.1 ×4 (mechanically compatible with ×8/×16 slots), enabling up to 8 Gb/s aggregate throughput across its four Gigabit ports. Each port supports 10/100/1000BASE‑T over twisted‑pair cabling. Key features include VLAN tagging, MSI‑X interrupts, jumbo frames, and IEEE 1588 time synchronization support. Virtualization-enhancing capabilities such as VMware NetQueue, Microsoft VMQ, and PXE/WOL improve performance under multi‑tenant loads. Energy-efficient Ethernet support optimizes power usage without compromising performance.

Advanced Options

Engineered for reliable multi‑port Gigabit connectivity, the 366FLR adapter provides stable line‑rate speeds across all four ports concurrently. Its Intel I350-based architecture supports advanced offloading, minimizing host CPU impact during virtualization and network-intensive workloads.
