Data center stranded power recovery design

A method for power distribution in a data center, comprising:

• providing power from a first power distribution unit (PDU) via a first busway segment to a first row of server racks, the first busway segment being an exclusive busway segment by which the first row of server racks can receive power;
• providing excess power from the first PDU via a second busway segment to a first set of server racks in a second row of server racks to service a workload power requirement of the second row of server racks, the excess power from the first PDU resulting from a workload assignment to the first row of server racks;
• providing power from a second PDU via a third busway segment to a third row of server racks, the third busway segment being an exclusive busway segment by which the third row of server racks can receive power;
• and
• providing excess power from the second PDU via a fourth busway segment to a second set of server racks in the second row of server racks to service the workload power requirement of the second row of server racks, the excess power from the second PDU resulting from a workload assignment to the third row of server racks;
• wherein the first, second and third rows of server racks are parallel to one another.

A power distribution system for a data center, comprising:

• a first row of server racks;
• a first busway that is operable to deliver power from a first power distribution unit (PDU) to each server rack in the first row of server racks, the first busway being an exclusive busway by which the first row of server racks can receive power;
• a second row of server racks;
• a second busway that is operable to deliver power from a second PDU to each server rack in the second row of server racks, the second busway being an exclusive busway by which the second row of server racks can receive power;
• a third row of server racks, wherein the first, second and third rows of server racks are parallel to one another;
• a third busway that is operable to deliver power from the first PDU to each server rack in the third row of server racks;
• and
• a fourth busway that is operable to deliver power from the second PDU to each server rack in the third row of server racks;
• wherein excess power from the first PDU and the second PDU that results from respective workload assignments to the first and second rows of server racks is provided via the third busway and the fourth busway, respectively, to service a workload power requirement of the third row of server racks.
