Pros & Cons
Pros
- ✓ Intel X550-AT2 chip, the same silicon as Intel's own X550-T2 dual-port NIC
- ✓ Dual RJ45 ports auto-negotiate 10G/5G/2.5G/1G/100M over existing copper
- ✓ PCIe 3.0 x4 card drops into x4, x8, or x16 slots; backward compatible with PCIe 1.1/2.0
- ✓ SR-IOV, VMDq, DPDK and iSCSI/FCoE offload make it viable for ESXi 6/7 hosts
- ✓ Ships with both low-profile and full-height brackets for slim cases and towers
Cons
- ✗ No macOS support at all, and OPNsense 25.7.3 is explicitly unsupported
- ✗ Bypass Mode is not supported, ruling out inline network-tap deployments
- ✗ X550 controllers run hot and need real chassis airflow, not a passive desktop case
- ✗ Drivers download separately from Intel's site rather than shipping on media
