In contrast to standard racks, OCP racks are powered centrally through a vertical bus that supplies power to the entire rack at the same time. The equipment in the rack is connected to the bus via dedicated terminals, which also simplifies the server design by eliminating the need for power supplies. Power shelves are used to supply power, which reduces the number of intermediate power conversions in transit, increasing the overall efficiency of the data center
The use of OCP racks saves energy, reduces the load on the cooling system and improves the energy efficiency of the entire data center
