1. A data center comprising:
a plurality of servers forming a plurality of server groups, each server group including two or more servers that are not part of any other one from the plurality of server groups, and each sever group powered by a respective first power supply and a respective second power supply in the server group, where each server group has different respective first and second power supplies and is powered only by its respective first and second power supplies, and wherein the first and second power supplies are powered by a multi-phase power input that includes a first phase and a second phase; one or more measuring devices configured to identify: a characteristic of a load placed on the first phase of the power input by servers from the plurality of server groups; and a characteristic of a load placed on the second phase of the power input by servers from the plurality of server groups; a managing terminal configured to:
receive, from the one or more measuring devices, a first indication of the load placed on the first phase;receive, from the one or more measuring devices, a second indication of the load placed on the second phase;detect an imbalance between the load placed on the first phase and the load placed on the second phase; andin response to the detected imbalance, reconfigure, a first server group, a first power supply of the first server group to output to a DC rail in the first server group a DC voltage that is either lower or higher than a DC voltage output to the DC rail in the first server group by a second power supply of the first server group;wherein the first power supply draws current from one of the first phase and the second phase, while the second power supply draws current from the other one of the first phase and the second phase; andwherein the servers from the first server group are connected to the DC rail and draw power from the DC rail, thereby providing a shared load on the first power supply and the second power supply. |
