Choice of airflow direction, allowing for significant savings in cooling costs
Low 130 W power rating and variable speed fans help reduce power consumption
Simple management with support for stacking up to 8 switches
Cloud ready: be aware of virtual machine movements with VMready® or create SDN with OpenFlow

Performance. Value. Availability.
The Lenovo RackSwitch G8052 features 48 x RJ-45 1 Gigabit Ethernet (GbE) ports plus 4 x SFP+ 10 GbE ports in a flexible 1U switch. All ports come standard, and the SFP+ ports can also support SFP 1 GbE if needed, Designed with top performance in mind, the G8052 provides line-rate, high-bandwidth switching, filtering, and traffic queuing without delaying data, and large data center-grade buffers to keep traffic moving. Redundant hot-swap power and fans, along with numerous high-availability features, mean that the G8052 is always available for business-sensitive traffic.

Cloud Perfect
The RackSwitch G8052 is virtualized—supporting VMready® technology, an innovative, standards-based solution to manage virtual machines (VMs) in small to large-scale data center and cloud environments. VMready works with all leading VM providers. The G8052 also features OpenFlow support to help easily create software defined virtual networks (SDN) and enables a remote controller to modify the behavior of network devices through a well-defined “forwarding instruction set. ”

Cool & Easy
The RackSwitch G8052 is cool—implementing a choice of directional cooling to maximize data center layout and provisioning. Its superior airflow design complements the hot-aisle and cold-aisle data center cooling model.

The RackSwitch G8052 is easy—with server-oriented provisioning via point-and-click management interfaces, along with the optional Switch Center software package for updating large groups of switches. And, the G8052 supports stacking for up to eight switches for simplified switch management using a single IP management address.
