Featuring a PCI Express 2.1 x4 interface and the Intel Ethernet Controller I350 architecture, this four-port 1 Gigabit Ethernet adapter delivers scalable throughput and dependable connectivity in a compact, HP-branded form factor. The 366T consolidates four independent 1Gb Ethernet ports into a single, power-efficient package, helping you maximize server I/O capacity while reducing total cost of ownership. Whether you are expanding a growing data center, upgrading an existing HP ProLiant deployment, or outfitting a rack with robust network access, this adapter offers simplicity, reliability, and solid performance for virtualization, clustering, and everyday networking tasks. With HP-tested compatibility and broad driver support across common operating systems, the 366T is designed to optimize virtualization, file sharing, backups, and multi-network workloads without sacrificing CPU cycles or energy efficiency.

• Quad-Port 1Gb Ethernet Performance with Intel I350 backbone: The HP 366T brings four independent 1Gb Ethernet ports to a single PCIe add-in card, enabling higher port density and aggregate throughput. Each port can be utilized for separate networks or combined for enhanced bandwidth in virtualization, clustering, or data-transfer tasks. Based on the Intel Ethernet Controller I350 architecture and delivered over PCI Express 2.1 x4, the card achieves low-latency, steady performance under load. Built-in offloads help reduce CPU overhead, while support for VLAN tagging and jumbo frames helps optimize traffic flows across diverse workloads. This combination yields reliable, scalable network access suitable for busy data centers and enterprise deployments.
• Energy efficiency and single-chip Ethernet integration: The 366T leverages next-generation Ethernet integration on a single chip, significantly reducing power requirements for four 1Gb ports. This energy-aware design lowers total power draw, minimizes heat generation, and improves efficiency in dense server environments. With a focus on performance-per-watt, the adapter maintains strong throughput while consuming less energy than older quad-port NICs. Its architecture aligns with modern data-center sustainability goals and HP’s commitment to long-term availability, ensuring a stable upgrade path and consistent operating costs as your infrastructure grows.
• Designed for HP ProLiant servers and HP networks: The 366T is engineered for seamless integration with HP ProLiant servers and HP networking ecosystems. It supports standard 1Gb Ethernet features and drivers across major operating systems, enabling swift deployment in mixed environments. HP branding signals validated compatibility with HP server platforms, while the card’s form factor options accommodate a variety of chassis configurations. With straightforward installation and reliable operation, it’s a practical upgrade for expanding network access without introducing compatibility concerns or extensive retraining for IT staff.
• Virtualization-ready and reliability-focused: Quad-port connectivity makes the 366T well-suited for virtualized workloads, where VM network separation and throughput are critical. The Intel I350-based controller supports traffic offloads and virtualization-friendly features that reduce CPU overhead and deliver predictable performance in virtualization platforms and clustering scenarios. The combination of four Ethernet ports, robust PCIe data transfer, and HP-tested reliability provides a solid foundation for mission-critical workloads such as database replication, shared storage access, and high-availability configurations, ensuring steady network connectivity under varying load.
• Easy integration, deployment, and lifecycle support: With its PCI Express x4 interface, the 366T installs easily in most HP-compatible servers. The four RJ-45 ports deliver straightforward copper Ethernet connections, and HP engineering ensures dependable operation across the server lifecycle. The adapter supports driver updates and is backed by HP’s support and warranty programs, offering a confident upgrade path for growing data centers and evolving networks. Its compact design and enterprise-grade reliability make it a practical, long-term networking solution for both new builds and incremental server upgrades.
