The present technology pertains to a system for cooling heat-producing systems (e.g., computing and information technology components) in a data center. The data center includes cells that have multiple subdivisions, and each subdivision includes primary coolant distribution units (CDUs) without backup CDUs (i.e., a CDU that is dormant until a primary CDUs fails). Opened valves between the subdivisions enable coolant from subdivisions having excess cooling capacity to flow to a failing subdivision that lacks sufficient cooling capacity to fully remove the heat produced by the heat-producing systems in the failing subdivision. Thus, the excess cooling capacity of the subdivisions can provide cooling redundancy to compensate for failing CDUs obviating the need for backup CDUs. The rows can be partitioned into failure domains such that a failure domain is isolated from cooling failures in other failure domains. The partitioning between failure domains can be reconfigured as needed.
