Cable-free power distribution in a rack
View Patent ↗A rack for housing electrically powered components, the rack including: a power distribution bus configured to distribute AC power among components installed in the rack via direct coupling without cables; a plurality of slots, each slot configured to receive a component; and one or more components, each component installed in one of the plurality of slots, each component directly coupled to the power distribution bus without a cable, at least one of the components comprising an inter-rack power distribution unit (‘PDU’) configured to provide AC power to other components installed in the rack via the power distribution bus.
1. A rack for housing electrically powered components, the rack comprising:
a power distribution bus configured to distribute Alternating Current (‘AC’) power among components installed in the rack via direct coupling without cables;
a plurality of slots, each slot configured to receive a component; and
one or more components, each component installed in one of the plurality of slots, each component directly coupled to the power distribution bus without a cable, at least one of the components comprising an inter-rack power distribution unit (‘PDU’) configured to provide AC power to other components installed in the rack via the power distribution bus.
2. The rack of claim 1 wherein:
each component comprises a power connector;
the power distribution bus comprises a channel adapted to receive the power connector of each component; and
each component is directly coupled to the power distribution bus upon installation of the component in the rack and insertion of the power connector of the component into the power distribution bus channel.
3. The rack of claim 1 wherein:
each component comprises a power connector receptacle;
the power distribution bus comprises a plurality of power connectors, each power connector adapted for insertion into a power connector receptacle; and
each component is directly coupled to the power distribution bus upon installation of the component in the rack and insertion of a power distribution bus power connector into the power connector receptacle of the component.
4. The rack of claim 1 further comprising one or more locking mechanisms configured to prevent unintentional removal of a component from a slot in the rack.
5. The rack of claim 1 , wherein the rack comprises a blade server enclosure and at least one of the components comprises a blade server.
6. A method of cable-free power distribution in a rack configured to house electrically powered components, the method comprising:
receiving, in each of a plurality of slots of the rack, one of a plurality of components, at least one of the plurality of components comprising an inter-rack power distribution unit (‘PDU’);
directly coupling a power distribution bus of the rack to each component without a cable upon receipt of the component in a slot of the server rack;
receiving, by the power distribution bus, Alternating Current (‘AC’) power from the inter-rack PDU; and
distributing, by the power distribution bus, the AC power received from the inter-rack PDU to other components in the rack.
7. The method of claim 6 wherein:
each component comprises a power connector;
the power distribution bus comprises a channel adapted to receive the power connector of each component; and
directly coupling the power distribution bus to each component further comprises receiving in the power distribution bus channel the power connector of the component.
8. The method of claim 6 wherein:
each component comprises a power connector receptacle;
the power distribution bus comprises a plurality of power connectors, each power connector adapted for insertion into a power connector receptacle; and
directly coupling the power distribution bus to each component further comprises receiving in the component's power connector receptacle a power connector of the power distribution bus.
9. The method of claim 6 further comprising preventing, by one or more locking mechanisms, unintentional removal of a component from a slot in the rack.
10. The method of claim 6 wherein the rack comprises a blade server enclosure and at least one of the components comprises a blade server.
11. A component configured for installation in a rack, the component comprising:
a coupling member, the coupling member configured to directly couple, without a cable, to a power distribution bus of a rack upon installation of the component in the rack, wherein the power distribution bus is configured to receive Alternating Current (‘AC’) power from an inter-rack power distribution unit (‘PDU’) and distribute the AC power to components installed in the rack.
12. The component of claim 11 , wherein the component comprises a blade server.
13. The component of claim 11 , wherein the component comprises the inter-rack PDU.
14. The component of claim 11 , wherein:
the coupling member comprises power connector;
the power distribution bus comprises a channel; and
the coupling member directly couples to the power distribution bus upon insertion of the power connector in the channel of the power distribution bus.
15. The component of claim 11 , wherein:
the coupling member comprises power connector receptacle;
the power distribution bus comprises a plurality of power connectors; and
the coupling member directly couples to the power distribution bus upon insertion of a power connector of the power distribution bus in the power connector receptacle of the component.
