The RackSwitch G8272 supports the following networking operating systems:
Lenovo Cloud Networking Operating System (CNOS)
The new Cloud NOS provides a simple, open and programmable network infrastructure designed to
scale for your business needs. Its intelligent, cloud-scale performance delivers a software-defined
Ethernet solution that is simple to manage and easy to deploy using common management tools.
Cloud NOS is based on open, industry standards for better data center interoperability, and it
enables support of automation and orchestration applications for tight integration into the data
center ecosystem.
With its high-performance architecture and support for an extensive set of routing protocols, Cloud
NOS provides reliable, high-performance fabric for traditional, converged and hyperscale
solutions. Cloud NOS can help you consolidate server and storage networks into a single fabric.
Converged Enhanced Ethernet delivers value for your iSCSI and NAS enterprise storage
environments.
Lenovo Enterprise Networking Operating System (ENOS)
The Lenovo ENOS is a data center-class network operating system 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, UFP, 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.
ENOS can help you consolidate server and storage networks into a single fabric. Converged
Enhanced Ethernet delivers value for your iSCSI, NAS and FCoE enterprise storage environments.
The RackSwitch G8272 with Cloud NOS offers the following additional features:
Automated VM-aware network provisioning
The Lenovo CNOS Network Policy Agent, a ThinkAgile Network Orchestrator feature, gives
increased visibility of the virtual infrastructure, including VM and virtual network information. It
provides automated VM-aware provisioning by automatically configuring VLANs in the physical
network based on the auto-discovered virtual network topology. The agent also performs ongoing
dynamic updates to the physical network configuration in response to new VMs, updated VMs,
and deleted VMs and virtual networks, eliminating errors with manual configuration.
Note: The Network Policy Agent works with the Nutanix software version 5.0.2 or higher.
Pro-active congestion monitoring
Telemetry enables continuous monitoring of networking devices to detect potential congestion
problems, such as packets dropped by the switch when ports are being used close to their line rate
or switch buffers are being temporarily overflown (for example, in case of microbursts).
Zero Touch Provisioning
Zero Touch Provisioning (ZTP) enables a switch to automatically provision itself using the resources
available on the network, without manual intervention. ZTP automatically handles the process of
upgrading the switch software image and installing configuration files.
Python Scripting
You can create and execute local Python scripts on switches to make small programs that allow a
switch to automatically provision itself, perform fault monitoring, upgrade the image files, or auto-
generate configuration files. You can implement version control systems, automatically generate
alerts, create custom logging tools, and automate the management of network devices.
REST API Programming
The Lenovo REpresentational State Transfer (REST) Application Program Interface (API) enables you
to remotely configure and manage a Lenovo switch using REST and HyperText Transfer Protocol
(HTTP). It also allows switch management integration into management applications, such as
Lenovo xClarity.
