HELP ?

With David Bombal on all platforms (Udemy, YouTube etc) -a single poit of contact is o

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

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)
