    High-speed performance and value

    You can’t afford to be saddled with an inflexible, underpowered Top of Rack (ToR) aggregation switch. That’s why we created the Lenovo ThinkSystem NE2572 RackSwitch, designed for the modern data center. It uses the latest Ethernet switch technology, so it’s lightning fast, offering up to 72 ports with speeds up to 100Gbps.

    It provides 48x 10Gb SFP+/25Gb QSFP28 and 6x 40Gb QSFP+/100Gb QSFP28 uplink ports that can be used to aggregate 25Gbps switches and servers. Break-out cables on the QSFP28 ports offer maximum scale and flexibility.

    Equipped with the Lenovo Cloud-optimized network operating system (CNOS), the NE2572 is tuned for Clos east-west networks. It’s designed with the scale and performance you need for cloud implementations and a software-defined data center (SDDC) and includes Lenovo XClarity integration to simplify data center management.

    High-availability features and advanced internal diagnostics provide the resilience required for the cloud.

    Open cloud architecture

    The open CNOS switches reduce data center OpEx via external interfaces that connect to the most-used data center management applications to automate virtual configuration changes. Supported applications include:

    • VMware Log Insight collects logs and events from NE2572 to find the root cause of issues and produces reports on symptoms across multiple devices and vendors.
    • OpenStack provides interrelated components that control diverse pools of processing, storage, and networking resources throughout a data center.
    • Nutanix Prism can automate switch VLAN changes and other options in Lenovo hyperconverged solutions
    • Ansible automation delivers simple IT automation that ends repetitive tasks and frees up DevOps teams for more strategic work.

    This enables you to use the software you prefer and avoid vendor lock-in.
