ATTO FastFrame NS12 SFP+ is a dual-port network card that saves PCI slots, providing a more flexible system design, while consuming up to 60% less energy than competitive solutions. Lower power ratings mean lower energy costs, lower data center maintenance fees, and less worries about heat dissipation. This high-performance card includes high-quality pluggable SFP+ optical transceivers - a hidden cost in some competing cards - and supports direct-attached copper cables.
