Product Guide

The Lenovo RackSwitch™ G8264 that uses 10Gb SFP+ and 40Gb QSFP+ Ethernet technology is

designed for the data center. It is ideal for today's big data, cloud, and optimized workload solutions. It is

an enterprise class Layer 2 and Layer 3 full featured switch that delivers line-rate, high-bandwidth

switching, filtering, and traffic queuing without delaying data. Large data center grade buffers help keep

traffic moving, while the redundant hot-swap power supplies and fans and numerous availability features

help provide high availability for business sensitive traffic.

The RackSwitch G8264 is ideal for latency sensitive applications, such as high-performance computing

clusters and financial applications. In addition to the 10 Gb Ethernet (GbE) and 40 GbE connections, the

G8264 also can use traditional 1 GbE connections. The G8264 supports the newest protocols, including

Data Center Bridging/Converged Enhanced Ethernet (DCB/CEE) for Fibre Channel over Ethernet (FCoE)

and iSCSI and network attached storage (NAS).

The RackSwitch G8264 is shown in the following figure.

The RackSwitch G8264 supports Lenovo Virtual Fabric, which helps clients significantly reduce the cost

and complexity that is related to I/O requirements of many virtualization deployments. Virtual Fabric helps

reduce the number of multiple I/O adapters to a single dual-port 10 G adapter and reduces the number of

cables and required upstream switch ports. By using Virtual Fabric, you can carve a dual-port 10 G server

adapter into eight virtual network interface cards (vNICs) and create dedicated virtual pipes between the

adapter and switch for optimal performance, higher availability, and improved security. With Virtual Fabric,

you can make dynamic changes and allocate bandwidth per vNIC so that you can adjust it over time

without downtime.

The RackSwitch G8264 offers the benefits of OpenFlow. OpenFlow is the new open application

programming interface (API) that enables the network administrator to easily configure and manage virtual

networks that control traffic on a "per-flow" basis. It creates multiple independent virtual networks and

related policies without dealing with the complexities of the underlying physical network and protocols.

With OpenFlow, clients can easily create user-controlled virtual networks, optimize performance

dynamically, and minimize complexity when it is used with an industry compliant OpenFlow controller.
