Highlights
- Optimized for applications requiring high bandwidth and low latency
- Create SDN with OpenFlow now and planned VXLAN support via software upgrade
- Support for 48 SFP+ ports with up to 72 10GbE SFP+ connections in a 1U form factor

Performance. Value.
The feature-rich Lenovo RackSwitch G8272 includes 48 x SFP+ 10 Gigabit Ethernet (GbE) ports plus 6 x QSFP+ 40GbE ports in a flexible 1U switch. The SFP+ ports support SFP 1GbE if needed.
Using only 123W of power, the G8272 uses less power than comparable switches. Also, redundant power supplies and cooling fans come standard, adding to the reliability and efficiency.

Perfect for Cloud
The G8272 supports many value-added features for modern cloud deployments including unified fabric port (UFP) to help improve performance and availability when using virtual NICs. UFP allows a SFP+ 10GbE port to be carved into as many as 4 virtual ports with the throughput speed of each port controlled by the switch.
The G8272 supports OpenFlow which helps easily create software defined virtual networks (SDN) and enables a remote controller to modify the behavior of network devices.

Ethernet Efficiency
Take advantage of the economics and performance of lossless Ethernet, which can significantly improve performance, reliability and predictability. The G8272 can help your data center evolve to a higher level by helping you to consolidate server and storage networks into a single fabric. Converged enhanced Ethernet can help deliver value for your iSCSI, NAS and FCoE enterprise storage environments. You can achieve lower costs, simplify management, attain higher performance, improve bandwidth utilization, and gain the flexibility your business needs.
