The RackSwitch G8272 with Enterprise NOS offers the following additional features:

Virtual Fabric

The RackSwitch G8272 can help customers address I/O requirements for multiple NICs while

reducing cost and complexity. By using Unified Fabric Port, you can carve a physical NIC into

multiple virtual ports (2 - 8 vPorts) and create a virtual pipe between the adapter and the switch for

improved performance, availability, and security.

Transparent networking capability

With a simple configuration change to Easy Connect Mode, the RackSwitch G8272 becomes a

transparent network device that is invisible to the core and eliminates network administration

concerns of Spanning Tree Protocol configuration and interoperability and VLAN assignments and

avoids any possible loops. By emulating a host NIC to the data center core, it accelerates the

provisioning of VMs by eliminating the need to configure the typical access switch parameters.

OpenFlow enabled

The RackSwitch G8272 offers benefits of OpenFlow. OpenFlow is the open 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. The RackSwitch G8272 is

also the ideal switch to use with industry compliant OpenFlow controllers.
