Incremental data center infrastructure commissioning

A method, comprising:

• verifying that mechanical infrastructure in a data center is configured to support cooling of:
• at least a power distribution system configured to provide electrical power support to a plurality of sets of rack computer systems in a plurality of computer spaces of the data center;
• or
• a particular set of rack computer systems in an individual one of the computer spaces of the data center,
• wherein the verifying comprises, prior to installation in the data center of the plurality of sets of rack computer systems or prior to installation of the particular set of rack computer systems:
• simulating electrical power consumption by the plurality of sets of rack computer systems via a plurality of load banks electrically coupled to the power distribution system, wherein the plurality of load banks serve as a test load that simulates electrical power consumption of one or more live loads, such that the power distribution system generates heat as a result of supporting the simulated electrical power consumption:
• or
• simulating electrical power consumption by the particular set of the rack computer systems in the individual one of the computer spaces via a load bank located in the individual one of the computer spaces and electrically coupled to the power distribution system, wherein the load bank serve as a test load that simulates electrical power consumption of one or more live loads, such that the power distribution system and the load bank located in the individual one of the computer spaces collectively generate, in the individual computer space, a quantity of heat associated with simulated electrical power consumption by the particular set of rack computer systems in the individual one of the computer spaces;
• and
• operating:
• a set of power system mechanical infrastructure concurrently with the simulated electrical power consumption via the plurality of load banks, such that operating temperatures of each portion of the power distribution system remain less than threshold operating temperatures associated with the respective portion of the power distribution system:
• or
• a computer space mechanical infrastructure, such that the computer space mechanical infrastructure removes the quantity of heat from the individual one of the computer spaces associated with the simulated electrical power consumption.
