Intel Ethernet 1350 QP 1Gb Server Adapter, Low Profile, CusKit

Server workloads demand reliable, high-throughput network connectivity, yet many systems ship with only a single Gigabit port. The Dell Intel Ethernet I350 QP 1Gb Server Adapter solves this by adding four independent Gigabit Ethernet ports in a low-profile, PCIe x4 card. Built on Intel's proven I350 controller, it delivers line-rate performance, hardware-based virtualization offloads, and advanced manageability for dense virtualized environments, edge appliances, and small form-factor servers.

Who is it for

IT administrators, system integrators, and data center operators who need to expand network capacity in space-constrained servers, network appliances, or security gateways. Ideal for virtualization hosts, software-defined storage nodes, and high-availability clusters where multiple NICs are essential for traffic separation, link aggregation, or failover.

Main features

• Quad-port 1GbE connectivity via a single PCIe 2.1 x4 slot, compatible with x4, x8, and x16 slots

Tips

For optimal performance, install this adapter in a PCIe x4 or wider slot and use Cat 5e or better cabling. Enable jumbo frames and link aggregation on the switch to maximize throughput for storage or VM migration traffic. The low-profile bracket is pre-installed; swap to the full-height bracket if your chassis requires it. Update the driver to the latest version from Dell or Intel to ensure compatibility with newer hypervisor releases.
