RackSwitch G8264

Product Guide (withdrawn product)

The RackSwitch™ G8264 that leverages 10Gb SFP+ and 40Gb QSFP+ Ethernet technology is specifically 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 power and 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 performance

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

G8264 also has the capability for 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) in addition

to iSCSI and network-attached storage (NAS).

Did you know?

The G8264 supports Virtual Fabric, which helps clients significantly reduce cost and complexity 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 8 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 is the first 10 GbE switch to offer 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 used

with an industry compliant OpenFlow controller.

and they do not need separate transceivers. For longer distances, the 10GBASE-SR transceiver can support distances up to 300 meters over OM3 multimode fiber or up to 400 meters over OM4 multimode fiber. The 10GBASE-LR transceivers can support distances up to 10 kilometers on single mode fiber. For extended distances, the 10GBASE-ER transceivers can support distances up to 40 kilometers on single mode fiber.

The G8264 plays a vital role with Virtual Fabric, which reduces costs and complexity in environments where four or more NICs are needed per server. An example is virtualization, where clients often need up to eight NICs per server. For more information, see Virtual Fabric at: http://www.ibm.com/systems/networking/software/virtualfabric.

Rack-optimized server aggregation: 1 GbE attached rack servers The design goal is to have the RackSwitch G8264 (10 GbE) switch at the distribution layer and RackSwitch G8000/G8052 (1 GbE) at the Edge/Access layer. The G8264 is also ideal at the distribution layer when you are looking to aggregate connections for access layer switches like the G8000 or G8052 which support forty-eight 1 GbE ports to the servers and four 10 GbE uplinks.
