What is Cumulus Linux - Data Center Networking

• Customers replacing proprietary Operating systems with Open Source Operating systems

• Creating an Open Ecosystem, with an agile, open scalable unprecedented cost savings

• Old days, server were monolithic, complex systems with lock in and don't scale like Sun Solaris with Sun HW and Software - can scale - no add-ons etc. Nowdays more flexibility with Linux

• Not so on networking hardware.Still have vendor Lock-in such as Cisco, Juniper etc.

• Cumulus Linux wants to change all that - just like Linux in the war of the servers

  • Other providers offering "White-box Switching"

    • Pica8

    • Open Switch

    • Big Switch

• Open Architecture - no longer tied to a single vendor

  • Choice of Applications

  • Choice of Operating System

  • Choice of Hardware

Cumulus Networks Hardware Compatibility List

ONIE (Open Network Install Environment)

ONIE is a 'single unified installer' that can be used across all Cumulus hardware supported switches

• Same was as we need software to boot a server and then allow you to install an OS like Linux or Windoze on the server.

• On a SWITCH we also need a 'boot loader' and ONIE to install the OS (Cumulus Linux) onto the switch

• ONIE allows you to download and install Cumulus Linux across the network (like PXE in servers)
