Intel Converged Network Adapter X520-DA2 Dual 10GbE SFP+ Main Picture

This 10Gb Ethernet network adapter from Intel provides dual SFP+ ports, each supporting 1 & 10GbE data rates. It is designed for bandwidth intensive applications where SFP+ infrastructure is already present (as opposed to the more common RJ45).

Please note that for optimal performance, this card requires a PCI-Express 3.0 slot with 8 or more available lanes. It includes both full and half-height brackets, for installation in normal and low-profile cases.
