    • Reduced I/O cost (CAPEX) with fewer adapters and cables to purchase
    • Reduced complexity (OPEX) with fewer components to manage and lower energy cost
  • Accelerated communications with lower latency across clustered applications and storage arrays with RDMA over Converged Ethernet (RoCE)
  • Web-scale and hyperconverged solutions

The NE2572 RackSwitch offers the following features and benefits:

  • High performance

    The 10 Gb/25 Gb Ethernet NE2572 RackSwitch with 40 Gb/100 Gb Ethernet uplinks provides a combination of low latency, non-blocking line-rate switching, and ease of management with 3.6 Tbps throughput.

  • Lower power and better cooling

    The front-to-rear or rear-to-front cooling design of the NE2572 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 NE2572 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.

  • Network virtualization

    The NE2572 switch supports VXLAN Gateway for VMware NSX integration. VMware NSX is a virtualized network software platform that offers a full set of networking services, such as logical switching, routing, firewall, load balancing, VPN, quality of service (QoS), and monitoring.

  • Converged fabric

    The NE2572 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 NE2572 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.

  • Automated VM-aware network provisioning

    The Lenovo CNOS Network Policy Agent, a ThinkAgile Network Orchestrator feature, gives increased visibility of the Nutanix (AOS version 5.0.2 or higher [excluding 5.1.2]) and VMware vSphere 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.

  • 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.

Warranty and maintenance

The NE2572 RackSwitch comes with a 3-year Customer Replaceable Unit (CRU) hardware limited warranty with 9x5 Next Business Day (NBD) parts delivered and includes a 3-year software license, which provides entitlement to software upgrades over that period. The options that are installed in the switch assume the switch’s base warranty and any Lenovo warranty service upgrade for the switch. Lenovo also allows one no-charge support call within 90 days of purchase to get assistance and help resolve problems with the configuration of recently purchased Lenovo network switches.

Some countries might have different warranty terms and conditions than the standard warranty. This is due to local business practices or laws in the specific country. Local service teams can assist in explaining country-specific terms when needed. Examples of country-specific warranty terms are second or longer business day parts delivery or parts-only base warranty.

If warranty terms and conditions include onsite labor for repair or replacement of parts, Lenovo will dispatch a service technician to the customer site to perform the replacement. Onsite labor under base warranty is limited to labor for replacement of parts that have been determined to be field-replaceable units (FRUs). Parts that are determined to be customer-replaceable units (CRUs) do not include onsite labor under base warranty.

If warranty terms include parts-only base warranty, Lenovo is responsible for delivering only replacement parts that are under base warranty (including FRUs) that will be sent to a requested location for self-service. Parts-only service does not include a service technician being dispatched onsite. Parts must be changed at customer’s own cost and labor and defective parts must be returned following the instructions supplied with the spares parts.

Also available are Lenovo Services warranty maintenance upgrades and post-warranty maintenance agreements, with a well-defined scope of services, including service hours, response time, term of service, and service agreement terms and conditions.

Lenovo warranty service upgrade offerings are country-specific. Not all warranty service upgrades are available in every country. For information about Lenovo warranty service upgrade offerings that are available in your country or area, refer to the following resources:

In general, the following Lenovo warranty service upgrades are available:

  • Warranty and maintenance service upgrades:
    • 3, 4, or 5 years of warranty service coverage
    • 1-year or 2-year post-warranty extensions
    • Foundation Service: 9x5 service coverage with next business day onsite response
    • Essential Service: 24x7 service coverage with 4-hour onsite response or 24-hour committed repair (available only in select countries)
    • Advanced Service: 24x7 service coverage with 2-hour onsite response or 6-hour committed repair (available only in select countries)
  • Basic Hardware Installation Services

    Lenovo experts can seamlessly manage the physical installation of your server, storage, or networking hardware. Working at a time convenient for you (business hours or off shift), the technician will unpack and inspect the systems on your site, install options, mount in a rack cabinet, connect to power and network, check and update firmware to the latest levels, verify operation, and dispose of the packaging, allowing your team to focus on other priorities.
