OCP Modular Data Center (MDC)

OCP Modular Data Center (MDC) is an Open Compute Project (OCP) data center facility specification that defines modular, Prefabricated Data Center (PDC) building blocks for deploying IT capacity in repeatable, interoperable units.

  • Standardized modular data center design and specification (data center infrastructure)
  • Prefabricated, transportable modules for IT, power, and cooling capacity (physical infrastructure)
  • Guidance for interoperability between OCP-compliant IT racks and facility modules (facility–IT integration)
  • Reference architectures for scalable, repeatable data center deployment in different environments (capacity planning and deployment)
  • Alignment with broader OCP principles for openness, efficiency, and multi-vendor ecosystems (open hardware ecosystem)

More About OCP Modular Data Center (MDC)

OCP Modular Data Center (MDC) is a facility-level specification within the Open Compute Project that defines how to design and deploy modular, PDC units that host OCP-compliant IT hardware. It addresses the problem space of delivering data center capacity as standardized modules rather than as one-off, custom-built facilities, with an emphasis on repeatability, interoperability, and alignment with OCP rack and power standards (data center infrastructure).

The Medical Device Connectivity (MDC) effort focuses on creating consistent definitions for modular data center building blocks, including IT modules, power modules, and cooling modules (physical infrastructure). These modules are designed to be factory-built, transported to site, and integrated as part of a larger facility or as standalone installations. The specification aligns with OCP rack and power distribution concepts so that OCP-compliant racks, servers, and network equipment can be hosted within MDC units with predictable mechanical, electrical, and environmental interfaces (facility–IT integration).

In enterprise and institutional environments, MDCs are used as an approach to deploy capacity in locations where traditional brick-and-mortar data centers are not planned or where capacity needs to be added in increments (capacity planning and deployment). Organizations can use MDC designs as templates when working with vendors or integrators, enabling a more standardized procurement and deployment process across multiple sites or regions. The modular concept also supports use cases such as edge locations, remote sites, or expansions adjacent to existing data centers (edge and distributed infrastructure).

Technically, the MDC work connects to established data center domains such as power distribution, cooling systems, structured cabling, and environmental control (data center engineering). It also interacts with OCP rack standards, open rack specifications, and OCP-compliant IT gear by specifying the space, power, and cooling envelopes necessary for such equipment. The project documentation provides reference designs, mechanical and electrical parameters, and integration guidelines that serve as a basis for engineering and vendor implementation (reference architecture and specification).

From a directory and taxonomy perspective, OCP Modular Data Center (MDC) fits into the category of data center facility standards and reference architectures (data center infrastructure standard). It is relevant to enterprise architects, data center planners, facilities engineers, and hardware platform teams that consume or deploy OCP-compliant infrastructure, providing a shared framework for planning modular facilities, coordinating with suppliers, and integrating OCP hardware into modular environments.
