GenAI sparks a data center shakeup

In this Light Reading Podcast, Corning's Brian Rhoney and Bob Whitman explained how fiber infrastructure and computing requirements in and across data centers need to change to support GenAI versus traditional cloud computing.

At a Glance

  • The type of fiber infrastructure in the data center that's required to support AI (05:48)
  • Does Corning's partnership with Lumen reflect moves other telcos intend to make to support AI workloads? (17:27)
  • How well does the current long-haul/interconnect fiber infrastructure support AI services? (18:51)

Generative AI (GenAI) workloads will require an immense amount of training and machine-to-machine connections within the data center. As a result, data center infrastructure will need to change to support this shift.

In this Light Reading Podcast, Brian Rhoney, director of enterprise market development for Corning Optical Communications, explains how fiber infrastructure and computing requirements will be different to support GenAI versus traditional cloud computing.

He's joined by Bob Whitman, global VP of carrier networks at Corning, who provides a look outside the data center at how fiber buildouts for longhaul networks and data center interconnect can support the rise of GenAI. 

Whitman also explains why Lumen recently looked to Corning to reserve 10% of Corning's global fiber capacity over the next two years to facilitate the buildout of its network and interconnect AI-capable data centers. He discusses whether Lumen's decision is reflective of what other service providers are planning for GenAI infrastructure, and how well current long-haul fiber infrastructure supports AI services.

Editor-in-Chief, Light Reading

Phil Harvey has been a Light Reading writer and editor for more than 18 years combined. He began his second tour as the site's chief editor in April 2020.

His interest in speed and scale means he often covers optical networking and the foundational technologies powering the modern Internet.

Harvey covered networking, Internet infrastructure and dot-com mania in the late 90s for Silicon Valley magazines like UPSIDE and Red Herring before joining Light Reading (for the first time) in late 2000.

After moving to the Republic of Texas, Harvey spent eight years as a contributing tech writer for D CEO magazine, producing columns about tech advances in everything from supercomputing to cellphone recycling.

Harvey is an avid photographer and camera collector – if you accept that compulsive shopping and "collecting" are the same.
