4XEM 44OU OCP Open Rack V3 – 21-Inch ORv3 Rack, 3,527 lb Capacity

Build high-density compute infrastructure around the Open Compute Project ecosystem with the 4XEM OCP Open Rack V3. Designed for ORv3 deployments, this open-frame rack provides a 21-inch equipment bay with 48 mm OpenU spacing for compatible OCP compute, storage, power, and networking infrastructure.

Built from durable SPCC steel, the rack supports up to 3,527 lb [1600 kg] of static load and 3,087 lb [1400 kg] of dynamic load, providing the capacity required for demanding AI, high-performance computing, cloud, and hyperscale data center deployments.

The ORv3 architecture supports 48V DC busbar power infrastructure and compatible blind-mate manifolds for liquid-cooling deployments. Its open airflow design provides an unobstructed airflow path for high-density equipment, while top and bottom cable routing provide flexible options for organizing power and data connections.

While designed around the 21-inch Open Rack standard, the rack also supports legacy 19-inch equipment through compatible adapter brackets, providing additional flexibility for environments transitioning between traditional EIA rack hardware and OCP infrastructure.

Optional front and rear doors and side panels allow the open rack to be configured for different deployment requirements. With its high load capacity, ORv3 architecture, liquid-cooling compatibility, and support for modern 48V DC rack power infrastructure, the 4XEM OCP Open Rack V3 provides a scalable foundation for next-generation data center deployments.
