Lenovo ThinkSystem NE10032 RackSwitch

Product Guide

The Lenovo ThinkSystem NE10032 RackSwitch that uses 100 Gb QSFP28 and 40 Gb QSFP+ Ethernet
technology is specifically designed for the data center. It is ideal for today's big data, cloud, and enterprise
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 NE10032 RackSwitch has 32x QSFP+/QSFP28 ports that support 40 GbE and 100 GbE optical
transceivers, active optical cables (AOCs), and direct attach copper (DAC) cables. The QSFP+/QSFP28
ports can also be split out into four 10 GbE (for 40 GbE ports) or 25 GbE (for 100 GbE ports) connections
by using breakout cables.

The NE10032 RackSwitch is ideal for latency sensitive applications, such as high-performance computing
clusters and financial applications.

The NE10032 RackSwitch is shown in the following figure.

Did you know?

With exceptional port density and flexibility with break-out cables, the NE10032 RackSwitch can support
up to 128x 10 GbE / 25 GbE Ethernet connections, or a mix of 10 GbE / 25 GbE server and storage
connections with 40 GbE or 100 GbE upstream network connections, or up to 32x 40 GbE / 100 GbE
connections in a 1U rack form factor.

The NE10032 RackSwitch runs the Lenovo Cloud Networking Operating System (CNOS) that 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.

Key features

The NE10032 RackSwitch runs the Cloud NOS that 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.

The NE10032 RackSwitch is considered particularly suited for the following environments:

Mixed 10 GbE, 25 GbE, 40 GbE, and 100 GbE server and storage connectivity and upstream
aggregation

Cloud and virtualization solutions with VM-aware network automation and integration into Lenovo
and third-party IT and cloud infrastructure management tools

Converged SAN and LAN network via NAS and iSCSI storage connectivity

Reduced I/O cost (CAPEX) with fewer adapters and cables to purchase
Reduced complexity (OPEX) with fewer components to manage and lower energy cost

Web-scale and hyperconverged solutions

Applications demanding better performance and lower latency

The NE10032 RackSwitch offers the following features and benefits:

High performance
The 10 Gb/25 Gb/40 Gb/100 Gb Ethernet NE10032 RackSwitch provides a combination of low
latency, non-blocking line-rate switching, and ease of management with 6.4 Tbps throughput.

Lower power and better cooling
The front-to-rear or rear-to-front cooling design of the NE10032 RackSwitch reduces data center air
conditioning costs by having airflow match the servers in the rack. In addition, variable speed fans
help reduce power consumption.

Layer 3 functionality
The NE10032 RackSwitch includes Layer 3 functionality, which provides security and performance
benefits, as inter-VLAN traffic stays within the switch. This switch also provides the full range of
Layer 3 protocols from static routes for technologies, such as Open Shortest Path First (OSPF) and
Border Gateway Protocol (BGP) for enterprise customers.

Converged fabric
The NE10032 RackSwitch supports Converged Enhanced Ethernet (CEE) which helps enable
customers to combine storage, messaging traffic, VoIP, video, and other data on a common data
center lossless Ethernet infrastructure. As a result, customers can deploy a single server interface
for multiple data types, which can simplify the deployment and management of server network
connectivity while maintaining the high availability and robustness that is required for storage
transactions.

Fault tolerance
The NE10032 RackSwitch offers redundant hot-swap hardware components, learns alternate routes
automatically, and performs faster convergence if there is a link, switch, or power failure.

Seamless interoperability
RackSwitch switches perform seamlessly with other vendors' upstream switches.

Lenovo ThinkSystem NE10032 RackSwitch 2

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 Acropolis Hypervisor (AHV) and Nutanix
Acropolis 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
Network administrators 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. Administrators can also 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
network administrators 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.
