What Is White Space?_
In a data center, white space refers to the floor area where compute, storage, and networking hardware is installed. It is distinct from the mechanical and electrical spaces that house cooling, power distribution, and backup systems. The layout of white space must accommodate rack rows, hot and cold aisles, and cable pathways for both power and data.
Technical Details
White space is typically measured in terms of raised floor tiles or square footage, with each rack occupying a defined footprint (e.g., 2x4 feet for a standard 600mm x 1200mm rack). For GPU clusters, white space must also account for liquid cooling distribution units (CDUs) and overhead cable trays for NVLink copper spine networks and fiber optic scale-out networks. The floor loading capacity in white space must meet the weight of fully populated GPU racks, per the OEM spec, and the area must be free of obstructions to allow for proper airflow and maintenance access.
How Leviathan Systems Works with White Space
During Leviathan Systems deployments, we define white space boundaries before rack assembly to ensure that GPU racks, CDUs, and cable trays are placed within the designated IT area, avoiding conflicts with facility columns or cooling pipes. Our field crew uses the white space plan to stage equipment and route structured cabling without encroaching on mechanical zones.
