Exact specifications and compatibility
| Dedicated subcategory | 10 Gigabit and server adapters |
|---|---|
| Exact product/model | Intel Ethernet Converged Network Adapter X520-DA2 |
| Bus, ports and physical interface | PCIe 2.0 x8; two SFP+ cages; qualified DAC, AOC or optical module required. |
| PHY, radio or protocol | Intel 82599ES controller; dual 10GbE SFP+ ports, module and firmware dependent. |
| Nominal rate (not measured) | Up to 10Gb/s per port; two-port aggregate 20Gb/s nominal, not measured throughput. |
| Measured throughput | No measured benchmark is claimed for a physical specimen. A valid result must record host/peer, link partner, media/cable, driver/firmware, traffic pattern, test tool and duration. |
| Drivers, OS and firmware | Linux ixgbe; Intel Windows Server and VMware support depend on adapter NVM, driver package and OS release. |
| Compatibility | PCIe x8 electrical slot and validated SFP+ media; verify switch compatibility and OEM transceiver qualification. |
| Variant warning | X520-DA2 dual SFP+ differs from X520-T2 copper, X520-SR2 OEM and X710-DA2. Check PBA, NVM and Intel/OEM driver support. |
