Lenovo RackSwitch G8264Product GuideThe Lenovo RackSwitch™ G8264 that uses 10Gb SFP+ and 40Gb QSFP+ Ethernet technology isdesigned for the data center. It is ideal for today's big data, cloud, and optimized workload solutions. It isan enterprise class Layer 2 and Layer 3 full featured switch that delivers line-rate, high-bandwidthswitching, filtering, and traffic queuing without delaying data. Large data center grade buffers help keeptraffic moving, while the redundant hot-swap power supplies and fans and numerous availability featureshelp provide high availability for business sensitive traffic.The RackSwitch G8264 is ideal for latency sensitive applications, such as high-performance computingclusters and financial applications. In addition to the 10 Gb Ethernet (GbE) and 40 GbE connections, theG8264 also can use traditional 1 GbE connections. The G8264 supports the newest protocols, includingData 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.Figure 1. Lenovo RackSwitch G8264Did you know?The RackSwitch G8264 supports Lenovo Virtual Fabric, which helps clients significantly reduce the costand complexity that is related to I/O requirements of many virtualization deployments. Virtual Fabric helpsreduce the number of multiple I/O adapters to a single dual-port 10 G adapter and reduces the number ofcables and required upstream switch ports. By using Virtual Fabric, you can carve a dual-port 10 G serveradapter into eight virtual network interface cards (vNICs) and create dedicated virtual pipes between theadapter 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 timewithout downtime.The RackSwitch G8264 offers the benefits of OpenFlow. OpenFlow is the new open applicationprogramming interface (API) that enables the network administrator to easily configure and manage virtualnetworks that control traffic on a “per-flow” basis. It creates multiple independent virtual networks andrelated policies without dealing with the complexities of the underlying physical network and protocols.With OpenFlow, clients can easily create user-controlled virtual networks, optimize performancedynamically, and minimize complexity when it is used with an industry compliant OpenFlow controller.Lenovo RackSwitch G8264 1
