Implementing prefabricated modular data centers has benefits like speed of deployment and predictability, but the process is different than traditional data centers. Some key differences in the process are that prefabricated data centers use system-level design instead of component design, have simplified site preparation since much work is done in the factory, and modules can be transported and installed more quickly than constructing systems on site. The practical considerations discussed in the document provide guidance for planning, permitting, procuring, and installing prefabricated modular data centers.
