Overview
The Intel I350-T4 is the reference four-port gigabit server adapter. Almost every hypervisor ships its igb driver in-box, and the four RJ45 ports make it the default choice for a dedicated management or out-of-band plane in an otherwise 10G/25G server.
It is also the standard multi-port NIC for firewall and router appliances: four independently DMA-queued ports with SR-IOV keep per-port latency predictable under heavy NAT or packet-filtering load.
Key Benefits
Driver-ubiquitous: igb is in-box everywhere. 4 independent ports for management/WAN segmentation. SR-IOV + VMDq for virtualized firewalls. Very low power: ≈ 4.4 W total.
Applications
Server management/iDRAC-style sideband aggregation, firewall and router appliances, 1G access-layer uplinks, industrial edge gateways, and lab breakout.
