RackSwitch G8264Product GuideThe RackSwitch™ G8264 that leverages 10Gb SFP+ and 40Gb QSFP+ Ethernet technology is specifically designedfor the data center. It is ideal for today's big data, cloud, and optimized workload solutions. It is an enterprise classLayer 2 and Layer 3 full featured switch that delivers line-rate, high-bandwidth switching, filtering, and trafficqueuing without delaying data. Large data-center grade buffers help keep traffic moving, while the redundant powerand fans along with numerous high availability features help provide high availability for business sensitive traffic.The RackSwitch G8264, shown in Figure 1, is ideal for latency sensitive applications such as high performancecomputing clusters and financial applications. In addition to the 10 Gb Ethernet (GbE) and 40 GbE connections, theG8264 also has the capability for traditional 1 GbE connections. The G8264 supports the newest protocols includingData Center Bridging/Converged Enhanced Ethernet (DCB/CEE) for Fibre Channel over Ethernet (FCoE) in additionto iSCSI and network-attached storage (NAS).Figure 1. RackSwitch G8264Did you know?The G8264 supports Virtual Fabric, which helps clients significantly reduce cost and complexity related to I/Orequirements of many virtualization deployments. Virtual Fabric helps reduce the number of multiple I/O adapters toa single dual-port 10 G adapter and reduces the number of cables and required upstream switch ports. By usingVirtual Fabric, you can carve a dual-port 10 G server adapter into 8 virtual network interface cards (vNICs) andcreate dedicated virtual pipes between the adapter and switch for optimal performance, higher availability, andimproved security. With Virtual Fabric, you can make dynamic changes and allocate bandwidth per vNIC so thatyou can adjust it over time without downtime.The RackSwitch G8264 is the first 10 GbE switch to offer benefits of OpenFlow. OpenFlow is the new openapplication programming interface (API) that enables the network administrator to easily configure and managevirtual networks 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. WithOpenFlow, clients can easily create user-controlled virtual networks, optimize performance dynamically, andminimize complexity when used with an industry compliant OpenFlow controller.RackSwitch G8264 1
