The Intel I350T4V2BLK Ethernet Server Adapter, commonly known as the Intel I350-T4, is a robust quad-port Gigabit Ethernet network interface card engineered for server and enterprise environments. Leveraging the Intel I350 gigabit controller silicon, this adapter delivers stable and efficient network connectivity with four independent 1 Gbps ports via a PCI Express 2.1 x4 interface, allowing high performance across wired networks using standard Cat5e copper cabling (up to ~100 m). Designed to support modern data infrastructure demands, the I350-T4 includes advanced features such as Intel Virtualization Technology for Connectivity (VT-c), Flexible Port Partitioning, and PCI-SIG SR-IOV support. These capabilities help reduce CPU overhead and improve throughput in virtualized environments by enabling efficient I/O virtualization and quality of service (QoS) functions directly on the adapter. Additionally, the adapter incorporates power-saving technologies like Energy Efficient Ethernet (EEE) and DMA Coalescing, which help lower overall power consumption and operational cost without sacrificing performance. Both low-profile and full-height brackets are provided for flexible installation across a wide range of server chassis. With broad operating system support (Windows, Linux, VMware, etc.) and enterprise-grade certifications, the Intel I350-T4 remains a popular choice for enhancing wired network capacity and reliability in server racks and virtualization hosts. Key Features & Benefits 1. Quad Gigabit Ethernet Ports- Provides 4 independent 1 Gbps RJ-45 network ports for maximum flexibility.
Ideal for multi-LAN traffic, link aggregation (LACP), VLAN segmentation, redundancy, and dedicated networks for different services (management, storage, VM traffic).
2. Intel I350 Controller with Advanced Networking - Uses Intel’s I350 Ethernet controller, known for enterprise-grade reliability and long-term support.
Compatible with standard Cat5e/Cat6 cabling at 10/100/1000 Mbps.
3. PCI Express 2.1 x4 Interface - Connects to a PCIe 2.1 x4 slot, ensuring sufficient bandwidth for all four Gigabit ports to operate at full capacity.
Works in both full-height and low-profile server chassis (brackets included).
4. Enterprise-Level Technologies - The adapter includes several advanced features that boost performance and efficiency in server environments:
- Intel® Virtualization Technology (VT-c) — enhances performance for virtualized workloads and improves QoS.
- Flexible Port Partitioning (FPP) — supports dividing physical ports into up to eight virtual interfaces.
- PCI-SIG SR-IOV support — allows efficient I/O sharing in virtualized environments.
- Energy Efficient Ethernet (EEE) — reduces power usage during low network activity.
- Intel-NIC offloads and QoS features — lower CPU load and improve throughput.
5. Broad OS Compatibility - Works with a wide range of enterprise operating systems, including Windows Server, Linux distributions, VMware ESXi, FreeBSD, and more — making it suitable for diverse IT environments.
6. Flexible Deployment & Redundancy - With four ports you can configure link aggregation, redundancy (failover), network segmentation, or dedicate ports to different tasks without extra hardware.
This is especially useful in data center, virtualization, and multi-tenant environments.
Typical Use Cases- ✔ Virtualized servers & cloud infrastructure – Supports efficient traffic distribution and virtualization offloads.
- ✔ Load balancing & failover setups – Aggregated multi-port designs increase resilience.
- ✔ Network segmentation & security zoning – Assign different networks to separate services.
- ✔ Enterprise LAN connectivity – Stable and scalable Gigabit links to core switches and storage
