at least one of the plurality of power supply units disposed within one of the plurality of power supply unit slots, wherein the at least one power supply unit receives AC power from the PCIB and outputs direct current (DC) power to a busbar; and
a battery back-up unit (BBU) element disposed within the chassis, wherein the BBU element charges from and discharges to the busbar.
2. The rack-level power infrastructure of claim 1 , wherein the PDU outputs DC power to a common rail.
3. The rack-level power infrastructure of claim 1 , wherein the PDU outputs DC power to the busbar.
4. The rack-level power infrastructure of claim 1 , further comprising:
a second PDU, wherein the PDU is cross-cabled with the second PDU to provide redundant AC power.
5. The rack-level power infrastructure of claim 1 , wherein the PDU comprises the BBU.
6. The rack-level power infrastructure of claim 1 , further comprising AC power outlets disposed within the PDU.
7. The rack-level power infrastructure of claim 1 , further comprising:
a distribution element disposed within the PDU, wherein the distribution element is a wiring scheme that distributes phase-balanced power to one or more power elements disposed within the PDU.
8. The rack-level power infrastructure of claim 7 , wherein the distribution element is coupled to the plurality of power supply units.
9. The rack-level power infrastructure of claim 1 , wherein the plurality of power supply units couple to and output power to one or more connectors disposed within the PDU.
10. A method for providing modular and scalable power infrastructure outside of usable rack space, comprising:
providing a chassis configured to mount on the side of a rack;
providing a power cable interface box (PCIB) disposed within the chassis, wherein the PCIB receives alternating current (AC) power;
providing a power distribution unit (PDU), wherein the PDU comprises a plurality of power supply units;
balancing power consumption via the PDU through a phase-balancing and distribution configuration;
providing at least one power supply unit disposed within a slot of the chassis, wherein the at least one power supply unit receives AC power from the PCIB and outputs direct current (DC) power to a busbar; and
providing a battery back-up unit (BBU) element disposed within the chassis, wherein the BBU element charges from and discharges to the busbar.
11. The method of claim 10 , further comprising outputting by the PDU DC power to a common rail.
12. The method of claim 10 , further comprising outputting by the PDU DC power to the busbar.
13. The method of claim 10 , further comprising cross-cabling a second PDU with the PDU to provide redundant AC power.
14. The method of claim 10 , wherein the PDU comprises the BBU.
15. The method of claim 10 , further comprising providing AC power outlets within the PDU.
16. The method of claim 10 , further comprising providing a distribution element disposed within the PDU, wherein the distribution element distributes phase balanced power to one or more power elements disposed within the PDU via a wiring scheme.
17. The method of claim 16 , wherein the distribution element is coupled to the plurality of power supply units.
18. The method of claim 10 , further comprising outputting power by the plurality of power supply units to one or more connectors disposed within the PDU.
19. An information handling system, comprising:
a processor;
a memory element coupled to the processor;
