What You Get with Cumulus Linux

Key Features and Benefits

  • Unnumbered Interfaces: Benefit from a simplified Internet Protocol (IP) approach for Border Gateway Protocol (BGP) and Open Shortest Path First (OSPF) with just one IP template for leaf nodes and one for spine nodes.
  • Redistribute Neighbor (RDNBR): Get virtual machine (VM) and host mobility by plugging your server into any RDNBR switch and making it Layer 3-discoverable on the fabric.
  • Prescriptive Topology Manager (PTM): Efficiently go from whiteboard to physical cable. With PTM, you can program your data center to verify connections and resolve issues faster.
  • RDMA over Converged Ethernet (RoCE): Realize blazing fast speeds and the lowest latencies with RoCE implementation that’s ready with just one line of code.
  • Virtual Routing and Forwarding: Run multiple network paths without the need for multiple switches, giving you traffic isolation and network segmentation for multiple devices.
  • Ethernet Virtual Private Networks (EVPN): Get the most advanced capabilities available for EVPN and allow legacy Layer 2 applications to operate over next-generation Layer 3 networks.
  • NVIDIA User Experience (NVUE): Opt for an API-driven management model that gives you the ability to unify your network management and deployments with the rest of the data center.
  • Scale Enhancements: Take advantage of multiple VNIs that can be mapped to a single Linux “device,” with bridges that support thousands of tunnels.

Differentiation through Cumulus Linux

  • Disaggregation: The open architecture using a Linux operating model unlocks the stack.
  • Native Security: From OpenSSH to authentication, Cumulus Linux keeps your switches secure.
  • Actionable Telemetry: NVIDIA NetQ provides powerful visibility into the status and health of the network, improving time-to-resolution and more.
  • Unified stack: With a unified operating model across compute and network, you'll reduce complexities and get guaranteed interoperability.
  • Software Driven: Our software writes directly to the silicon, giving you a software-driven and hardware-accelerated approach.
  • Abstracted Visualization: NVIDIA Air enables you to create a replica of your network in the cloud so you can validate and prototype any change or addition to your network.
