Two ports wasn't enough. You've got storage, compute, and management traffic all wanting a lane and your NIC is the bottleneck. The Intel E810-DA4 gives you four SFP28 uplinks in a single PCIe slot — each running 10 or 25GbE independently. One card, four paths, no more daisy-chaining two dual-port adapters and burning through your slot budget. Intel chipset, Lenovo ISG build, ThinkSystem firmware support. You slot it, you cable it, you're done
