The Netberg Aurora 421 is a 10GbE multi-role switch suited for Top-of-Rack/Spine Data center, Enterprise, and CSP network deployments. It has 48 x 10GbE SFP+ and 6 x 100GbE QSFP28 interfaces and supports up to 64 interfaces using DAC break-out cables.

The system uses Broadcom Trident3-X5 silicon that introduces data plane programmability for the 10G market. The programmable pipeline allows new features to be added after deployment using in-field upgrades, providing capex investment protection for operators.

Support for new overlays and tunneling such as GENEVE, NSH, VXLAN, GPE, MPLS, MPLS over GRE/UDP, GUE, ILA, and PPPoE, new instrumental features bring intelligence to the network and push service capacity to the next level.

Performance is backed by a quad-core Intel Atom C3508 processor, up to 32GB DDR4 memory, and a 32GB SSD drive for application deployment. RAS features include a redundant hot-swappable power supply (1+1) and fans (N+1) for lower maintenance costs. The switch has a BMC (Baseboard Management Controller) onboard to provide server-like monitoring and power control functions through a shared Ethernet interface.

The system supports Netberg SONiC as the complete switching package, Ubuntu Linux and OpenBCM Broadcom Core Switch Software Development Kit (SDK) allow custom application development, and InfiniCore Visibility Studio for network visibility and management solutions.


Simplified deployment
  • With full Open Network Install Environment (ONIE) support, network operators can install the target Network Operating Systems (NOS) as part of data center provisioning in the fashion that servers are provisioned.
Network monitoring
  • Programmable support for enhanced network telemetry, including per-packet timestamping, Flow Tracker, microburst detection, latency/drop monitor, Active-probe-based in-band network telemetry, and in-band OAM processing; integrated with open-source BroadView v2 telemetry agent and analytics software
  • 48 x 1/10GbE SFP28 ports
    6 x 100/40GbE QSFP28
  • 1.28Tbps Broadcom Trident3-X5 BCM56771
  • Intel Atom C3508 quad core processor for application deployment
  • Up to 32GB of DDR4 memory (8GB default)
Reliable hardware platform
  • Redundant 450W 1+1 power
  • Redundant N+1 cooling
Network OS (NOS) options
  • Ubuntu Linux with open Broadcom SDK for application development.
  • SONiC offers a full suite of network functionality, like BGP and RDMA, that has been production-hardened in the data centers of some of the largest cloud service providers.
  • InfiniCORE Network Visibility Studio transforms the Aurora 421 into a visibility powerhouse, leveraging the programmability in the Trident3-X5 chipset. Visibility Studio provides a full data path design environment known as the NextIO Design Environment right from the Web-based UI.
