Server rack architecture that facilitates reduced current density

摘要

A server rack with vertically stacked shelves is disclosed. The shelves are used for housing loads (e.g. servers) and power supply units. Thus, both the power supply units and the servers are vertically stacked in the rack. An array of vertical and horizontal busses is secured to the back side of the server rack to electrically couple the servers with the power supply units. The arrangement of the PSUs and the busses provides for uniform current density across the server rack. The devices placed on the shelves are accessible and serviceable from the front of the server rack. The server rack can be placed within or secured to a device, system or a server room in a vertical orientation, a horizontal orientation or at an angle.

主权项

1. A server rack, comprising:
vertically stacked first and second shelves, wherein the first shelf is located above the second shelf; first and second vertical busses each coupled to a back side of the server rack; a first set of multiple power supplies connected at various different locations of the first vertical bus; a first set of multiple horizontal buses that connect the first vertical bus to a first set of multiple servers, wherein each horizontal bus in the first set of multiple horizontal buses respectively couples the first vertical bus to a respective server from the first set of multiple servers, and wherein the first offset of multiple servers receives power from the first set of multiple power supplies; and a second set of multiple power supplies connected at various different locations of the second vertical bus; a second set of multiple horizontal buses that connect the second vertical bus to a second set of multiple servers, wherein each horizontal bus in the second set of multiple horizontal buses respectively couple the second vertical bus to a respective server from the second set of multiple servers, and, wherein the second set of multiple servers receives power from the second set of multiple power supplies.
