The presentation discusses the future of more efficient datacenters using open source technologies. It introduces representatives from the Open Compute Project and Submer who will discuss how embracing open standards can significantly reduce datacenter energy usage and costs. Viewers are invited to ask questions in the YouTube chat. The presentation will cover current OCP projects and how open source innovations in areas like server virtualization, machine learning, and rack design have already reduced datacenter energy usage by 50% or more. Adopting these open technologies globally could reduce total datacenter energy usage by 80% or more according to presenters.

28. If all the world were to adopt these open
source vanity free infrastructures today, the
worlds total energy used by datacenters
would reduce by at least 50%.

30. Combined Heat & Compute (CHC)

31. If we then factor in the use of Combined
Heat & Compute (CHC) then tomorrow we
would see more than an 80% reduction in
the total energy consumed by all the
world’s datacenters.

33. 1. Whatever market open source
enters it eventually dominates.
2. The lowest cost technology always
wins in the end.
