Intel I350-F4 Quad-Port Gigabit SFP Network Adapter (I350-AM4)

The Intel I350-F4 is a high-performance, power-efficient PCI Express 2.1 x4 quad-port Gigabit fiber network interface card (NIC). Driven by the industry-proven Intel® Ethernet Controller I350-AM4, this adapter is designed to support high-density virtualization, iSCSI SAN environments, and reliable enterprise networking over fiber-optic infrastructure using SFP modules.

3. Advanced Features & Virtualization

Intel® Virtualization Technology for Connectivity (VT-c)

• SR-IOV (Single Root I/O Virtualization): Supports standard PCI-SIG SR-IOV. It can allocate up to 8 Virtual Functions (VFs) per port directly to Virtual Machines (VMs), lowering latency and reducing CPU overhead on host hypervisors.

• VMDq (Virtual Machine Device Queues): Offloads network data sorting from the software virtual switch to the network controller silicon to boost overall VM packet throughput.

• Flexible Port Partitioning: Allows the physical port to be split into multiple virtual ports, offering granular Quality of Service (QoS) controls.

Storage & Protocol Support

• iSCSI Boot: Native support for remote iSCSI boot, enabling cost-effective, diskless server deployments.

• Intel® I/O Acceleration Technology (I/OAT): Improves system throughput and reduces CPU utilization.

• Checksum Offloads: Supports TCP/IP/UDP checksum offloads and Large Send Offloads (LSO/TSO) for both IPv4 and IPv6.

4. Power & Environmental Specs

• Power Consumption (Typical): ~4.0 W to ~5.0 W (highly power-efficient; power consumption scales depending on the power draw of the plugged SFP modules)

• Power Source: Bus powered via PCIe slot (no external power connector needed)

• Operating Temperature: $0^\circ\text{C}$ to $55^\circ\text{C}$ ($32^\circ\text{F}$ to $131^\circ\text{F}$)

• Storage Temperature: $-20^\circ\text{C}$ to $65^\circ\text{C}$ ($-4^\circ\text{F}$ to $149^\circ\text{F}$)

• Compliance & Certifications: FCC Class B, CE, RoHS, IEEE 802.3z (Gigabit Fiber), IEEE 802.1Q (VLANs), IEEE 802.1p (Priority Queues), IEEE 802.3ad (LACP Link Aggregation)
