Who makes dcim, digital twins, capacity planning for AI data centers

DCIM platforms sit above every physical system in the facility — power distribution, cooling, rack space, network ports — and turn sensor and asset data into a single model operators use to plan capacity and catch problems before they cause an outage. As racks get denser and liquid cooling loops add another set of variables to track alongside power and airflow, the planning problem DCIM tools solve gets harder, and the digital-twin approach (modeling the facility before and during construction, not just monitoring it afterward) becomes more useful for validating a design ahead of costly retrofits.
