HPE811544-001

(366T) Ethernet Quad-Port 1 GbE Network Adapter (Intel I350, PCIe 2.1 ×4)

The HPE811544-001 (also known as 366T or 811546-B21) is a quad-port 1 Gigabit Ethernet Network Adapter based on the Intel I350chipset. It features four RJ-45 copper ports and delivers reliable 10/100/1000 Mbps performance across all ports. Ideal for server consolidation, virtualization, NIC teaming, and segmentation, this adapter is optimized for HPEProLiant Gen9/Gen10 rack and tower servers. Its virtualization-focused architecture and efficient PCIe performance make it well-suited for modern enterprise workloads.

Features

This adapter connects via a PCI Express 2.1 ×4 interface and supports auto-negotiation, full-duplex operation, and link speeds up to 1 Gbps per port. With Intel's proven I350 controller, the card supports virtualization acceleration technologies such as Intel® Virtualization Technology for Connectivity, RSS, MSI-X, Jumbo Frames, and large send offload. The quad-port configuration is excellent for network redundancy, segmentation, or separate network fabrics. HPE-certified and backward-compatible with various DL/ML/XL server models ensures reliable integration. It supports SNMP-based remote monitoring via the adapter's MIBs.

Advanced Options

Equipped with Intel's I350 chipset, the adapter delivers enterprise-grade performance with low latency and minimal CPU usage thanks to hardware offloads like checksum segmentation and interrupt moderation. Each port operates at line-rate with support for jumbo frames (up to 9,500 bytes MTU) for enhanced throughput in virtualization and storage traffic.
