Designing for higher densities is starting to change how data halls are planned. What was once a facility-led process is increasingly being influenced by what happens at the rack, particularly as airflow, containment, and thermal performance become harder to manage at scale. Rack-level cooling approaches are moving from niche to mainstream, giving operators more control over performance but also introducing new design considerations around layout, power, and integration with the wider cooling system. This episode will discuss:

• The core airflow and thermal thinking behind rack containment, and how systems like the S-Series are designed to manage heat at the cabinet level
• What it actually looks like to design a hall around rack containment, including layout, power, and how it ties back to the wider cooling infrastructure
• How far airside cooling can realistically go, from standard deployments through to higher-density GPU environments, and where liquid starts to come into play
• The practical considerations that come with this approach, from safety features like fire suppression and enclosure ratings to how operators plan for upgrades without starting from scratch
