Cumulus Linux 2.5 Overview


Published on

Cumulus Linux 2.5 makes it easy to adopt modern DataCenter Networking.

With new options for network architecture and validated designs, it is easier to migrate to modern data center networks.

Making it easy
– Design: Drop in switch running Cumulus Linux in existing network architecture, simplify migration with validated designs
– Procure: Making it simpler with expanded channel partners coverage (42 WW + Dell)
-- Deploy: Making it easy to support with First class Support organization –24x7 Coverage WW
