Intel X550T2 ETHERNET Network Adapter X550-T2

The Intel X550-T2 brings two full 10Gb/s Ethernet ports to servers and workstations via a single PCIe 3.0 x16 add-in card — and it does so over standard RJ-45 copper cabling, which is the practical differentiator from SFP+-based alternatives. That 10GBase-T design choice means organizations already running Cat 6A structured cabling can upgrade to 10Gb/s networking without touching their patch panels, wall plates, or switches that support 10GBase-T ports. The PCIe 3.0 interface provides 8GT/s per lane, delivering more than enough bus bandwidth to simultaneously saturate both 10Gb/s ports without creating a PCIe throughput ceiling.

Beyond raw connectivity, the X550 silicon's SR-IOV capability positions this card as a serious option for virtualized infrastructure — hypervisor administrators can partition each physical port into multiple virtual functions, assigning them directly to VMs and bypassing the hypervisor's software switching layer for measurably lower latency and CPU overhead. Intel's ixgbe driver is included in the Linux kernel mainline, which translates to seamless deployment on virtually any modern server Linux distribution. For NAS builders, home labs, and production workstations moving large files across a 10Gb/s local network, this card represents a mature, well-supported solution backed by Intel's enterprise driver track record.
