Lenovo RackSwitch G8272
Product Guide
The Lenovo RackSwitch™ G8272 that uses 10 Gb SFP+ and 40 Gb 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 hot-swap redundant power supplies and fans (along with numerous
high-availability features) help provide high availability for business sensitive traffic.
The RackSwitch G8272 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
G8272 can use 1 GbE connections.
The RackSwitch G8272 is shown in the following figure.

Did you know?
With exceptional port density and flexibility with break-out cables, the RackSwitch G8272 can support up
to 72x 10 Gb Ethernet connections in a 1U rack form factor.
The RackSwitch G8272 offers a choice of the Networking Operating Systems (NOS):
The Cloud NOS provides a simple, open and programmable network infrastructure with cloud-scale
performance. It delivers a software-defined Ethernet solution that is simple to manage and easy to
deploy using common management tools, and it enables support of automation and orchestration
applications for tight integration into the data center ecosystem.
The Enterprise NOS is a data center-class NOS progressively developed over the past decade to
deliver highly reliable, high-performance Ethernet and converged switching and interoperability with
existing network infrastructures. ENOS has a feature-rich design with virtualization, high availability,
and enterprise class Layer 2 and Layer 3 functionality. ENOS supports OpenFlow which helps easily
create software defined virtual networks (SDN) and enables a remote controller to modify the
behavior of network devices.
The RackSwitch G8272 supports the Open Network Install Environment (ONIE) which is a small Linux-
based operating system that provides an open install environment for networking devices without
operating systems.

    It has a throughput of 1.44 Tbps. Lower power and better cooling The RackSwitch G8272 uses as little as 123 W of power, which is less than comparable switches use. The front-to-rear or rear-to-front cooling design of the RackSwitch G8272 reduces data center air conditioning costs by having airflow match the servers in the rack.
