Cumulus Networks delivers the first multi-platform, multi-silicon 100G Open Networking solution

Mountain View, CA, May 31, 2016 - Cumulus Networks® announced today the immediate availability of Cumulus® Linux® 3.0, the latest release of the leading Linux Network Operating System, targeting customers building next generation public and private clouds.

“Public and private clouds are quickly driving towards web-scale IT, where open, scale out systems rule. The advent of 100G Ethernet brings 2.5 times the network bandwidth and unprecedented flexibility in network design that future-proofs the current wave of cloud buildout. Cumulus Linux 3.0 gives customers choice with access to a broad set of 100G platforms with support for both Broadcom Tomahawk and Mellanox Spectrum chip sets”, said JR Rivers, co-founder and CTO, Cumulus Networks.

With Open Networking experiencing mainstream adoption, Cumulus Linux 3.0 adds the following platforms to its industry leading Hardware Compatibility List, which now includes support for over forty platforms based on eight chip-sets from two silicon vendors, giving customers unprecedented choice to build best of breed data-center networks:

  • 100G
    • Dell Z9100 (Broadcom Tomahawk)
    • Mellanox SN2700 (Mellanox Spectrum)
    • Penguin Computing 3200CP (Broadcom Tomahawk)
    • Supermicro SSE-C3632 (Broadcom Tomahawk)
  • 40G
    • Mellanox SN2700B (Mellanox Spectrum)
  • 10GT
    • Dell S4048T (Broadcom Trident2+)

  • BGP Unnumbered and RFC 5549 enhancements for better v4/v6 dual stack networks
  • BGP/OSPF based Redistribute Neighbor for simple, dynamic routing to hosts

With Cumulus Linux 3.0, Cumulus Networks continues to lead the industry’s transition to open networking solutions with a variety of system innovations:

  • A Debian 8 base with 4.1 Linux kernel and an enhanced Linux networking stack
  • Cumulus Linux Virtual Machine (Cumulus VX) now includes hardware emulation, complete with ONIE, allowing it to be a complete learning and pre-production tool
  • Extended Support Release (ESR) for Cumulus Linux 2.5 provides customers the option to choose between the mature 2.5 release and the new Cumulus Linux 3.0, with latest feature-set for their environments. ESR will be supported and maintained for 3 years from the time of announcement.
