1. A rack-level power infrastructure, comprising:
- a power distribution unit (PDU), wherein the PDU receives alternating current (AC) power from an external power source;
a busbar coupled to the PDU, wherein the PDU outputs direct current (DC) power to the busbar;
at least one server coupled to and receiving DC power from the busbar; and
a battery back-up unit (BBU) element coupled to the busbar, wherein the BBU element charges from and discharges to the busbar.

Abstract
In accordance with the present disclosure, a scalable and modular rack-level power infrastructure is described. The power infrastructure may include a power distribution unit (PDU), which receives alternating current (AC) power from an external power source. The PDU may be coupled to a busbar and output DC power to the busbar. The busbar may be coupled to a server within a rack-server system and provide DC power to the server. Additionally, the infrastructure may include a battery back-up unit (BBU) element coupled to the busbar. The BBU element may charge from and discharge to the busbar.
