Cloud Network Operating SystemDatasheet
Intelligent OS for today and the future
Low Total Cost of Ownership
The Lenovo Cloud Network Operating System (CNOS) provides great value to customers. With all features included and free updates and upgrades, Lenovo customers experience 24% to 50% lower operational expenses and 38% to 111% higher return on investment* than with other networking vendors.
Data Center Interoperability
The Lenovo CNOS is open and interoperable. It is designed from the ground up for modern software defined data centers and can scale out easily. Its intelligent, cloud-scale performance delivers a software defined Ethernet solution that is simple to manage and easy to deploy using common management tools and industry-standard CLI.
CNOS includes support for the leading management, automation, and orchestration applications for tight integration into the data center ecosystem. CNOS is standard on the Lenovo ThinkSystem RackSwitch family of switches and select G Series systems.
Intelligent Management and Control
CNOS has evolving smart applications for telemetry, machine learning, and software defined networking. You can monitor the health of the network, use our industry-first intelligent software to predict and prevent issues before they happen, and automatically optimize the network for smooth application performance. Stay ahead of the curve instead of finding out about network outages after the fact and reacting to them.
Lenovo intelligent Network Controller (LiNC) supports containers securely, migrates policies, and supports virtual machines (VMs) as well. Lenovo Network Advisor, a Splunk application, analyzes telemetry and presents recommendations for LiNC to mitigate with confirmation from the operator.
LiNC can manage and orchestrate multi-cloud data centers. It can help you to reduce risks and downtime while ensuring that your network is performing at an optimum level.
As your business grows, your network needs to grow and scale. Lenovo switches with CNOS for your network can grow seamlessly and interoperate with other vendor networks giving you the flexibility you need.
Lenovo (HKSE: 992) (ADR: LNVGY) is a US$45 billion Fortune 500 company and a global technology leader in driving Intelligent Transformation. Lenovo’s data center solutions (ThinkSystem, ThinkAgile) are creating the capacity and computing power that are changing business and society.
