This colloquialism for “make my vehicle better” is an appropriate perspective on our recently released Cumulus Linux 3.0, or as we like to say around the office, “3.0.” Our engineering team looked at the upcoming market changes and decided to give Cumulus Linux a pretty sweet makeover.

Starting with the “IP mindset” that prevails in modern deployments, our team worked with the Linux kernel community to add Virtual Routing and Forwarding (VRF) to the kernel and hardware support to Cumulus Linux. VRF is coupled with BGP unnumbered interfaces as an even simpler way to deploy multi-tenant dual-stack IPv4/IPv6 networks.

In parallel, we looked at the image installation and upgrade mechanisms, revamping the build, packaging, and base installer. As a result, 3.0 is based on Debian 8 (Jessie) and Linux kernel 4.1, tied together with an entire system that enables the development flexibility of Linux coupled with the testing and support required for wide-scale, enterprise production deployments.

All of this functional horsepower is applied to seven new hardware platforms continuing Cumulus Networks’ industry leading support for Open Networking systems. These platforms cover the gamut of speeds, feeds, and functions; introducing Mellanox Spectrum alongside Broadcom Tomahawk and Trident-II+, giving customers more choices than ever before:

  • 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 Trident-II+)
    • EdgeCore AS5812T (Broadcom Trident-II+)

3.0 provides an awesome foundation for public and private clouds that are quickly driving towards 25/50/100G Ethernet to support their business. With 2.5 times the bandwidth, this wave of technology enables the transition to web-scale IT with unprecedented price and performance.

Don’t take my word for it. Over the next few weeks, the engineers responsible for 3.0 will be publishing blog posts with a “what is it and why do you care” perspective on their work developing some of the most important features in the release, giving you a deep dive into the major innovations we made in 3.0.

In the meantime, you can download Cumulus Linux 3.0 for use on hardware or in virtual machines.

Buckle up, and get ready to ride!
