1.5 IBM System Networking RackSwitch G8264
The RackSwitch G8264 is a 10 Gb/40 Gb Top-of-Rack switch designed for applications that
require the highest performance. It combines state of the art 1.28 Tbps throughput with up to
64 10 Gb SFP+ ports in an ultra-dense 1U form factor.

RackSwitch G8264 is also designed to support IBM Virtual Fabric, which helps clients reduce
cost and complexity when it comes to the I/O requirements of most virtualization
deployments. Virtual Fabric can help clients reduce the number of multiple I/O adapters down
to a single dual-port 10 G adapter, and reduce the number of cables and upstream switch
ports required. Virtual Fabric allows clients to carve a dual-port 10 G server adapter into eight
virtual NICs (vNICs) and create dedicated virtual pipes between the adapter and the switch
for optimal performance, higher availability, and better security. With Virtual Fabric, IT can
allocate bandwidth per vNIC and dynamically change, making room for the ability to adjust
over time without downtime.
With the flexibility of the RackSwitch G8264 switch, clients can take advantage of the
technologies that they require for multiple environments. The 40 Gb ports can also take
advantage of the QSFP+ Break-out cables to gain an additional 16 x 10 Gb ports. For 40 Gb
to 40 Gb connections, you can use QSFP+ direct-attached cables (DAC cables), which can
be 1 - 3 meters in length and are ideal for connecting chassis together or connecting to
another Top-of-Rack switch. For 40 Gb connectivity over longer distances, use a QSFP+
transceiver and QSFP+ MTP optical cables to connect up to 4 x 10 Gb ports using fiber
(10 Gb transceivers are needed at the other end).
