Abstract

A system includes a top-of-rack, a first plurality of chassis, and a first backplane. The first plurality of chassis each includes at least one rack module and a chassis network switch that connects to each of the at least one rack module. The first backplane includes a first backplane network switch that connects to the top-of-rack and connects to each of the first plurality of chassis via the chassis network switch of each of the first plurality of chassis.

First claim

The invention claimed is:

1. A system comprising:
a first plurality of chassis, each of the first plurality of chassis comprising at least one first rack module and a first chassis network switch coupled to each of the at least one rack module;
a first backplane comprising a first backplane network switch that is coupled to each of the first plurality of chassis via the first chassis network switch;
a second plurality of chassis, each of the second plurality of chassis comprising at least one second rack module and a second chassis network switch coupled to each of the at least one second rack module;
a second backplane comprising a second backplane network switch that is coupled to the first backplane via the first backplane network switch and is coupled to each of the second plurality of chassis; and
a top-of-rack that is coupled to the first backplane via the first backplane network switch, the top-of-rack being coupled to the second backplane via the first backplane network switch and the second backplane network switch.

2. The system of claim 1 , wherein the top-of-rack is coupled to a plurality of server racks.

3. The system of claim 1 , wherein the first backplane network switch is coupled to each of the first plurality of chassis via a chassis connector on each of the first plurality of chassis and a corresponding backplane connector on the first backplane.

4. The system of claim 1 , wherein each of the at least one rack module includes a computing sled.

5. The system of claim 1 wherein at least one of the backplane network switch or the chassis network switch includes a local area network (LAN) switch integrated circuit (IC).

6. The system of claim 1 , wherein each of the at least one rack module includes a network port, and the chassis network switch is coupled to the network port of each of at least one rack module.

7. The system of claim 6 , wherein each network port is a local area network (LAN) port or a RJ45 port.

8. A system comprising:
a first backplane comprising:
a first backplane top connector;
a first backplane bottom connector; and
a first backplane network switch that is coupled to the first backplane top connector and to the first backplane bottom connector, wherein the first back plane network switch is coupled to each of a first plurality of chassis via a first chassis network switch, each of the first plurality of chassis comprising at least one first rack module, the first chassis network switch coupled to each of the at least one first rack module;

a second backplane comprising:
a second backplane top connector that is coupled to the first backplane bottom connector;
a second backplane bottom connector; and
a second backplane network switch that is coupled to the second backplane top connector and to the second backplane bottom connector, wherein the second back plane network switch is coupled to each of a second plurality of chassis via a second chassis network switch, each of the second plurality of chassis comprising at least one second rack module, the second chassis network switch coupled to each of the at least one second rack module; and

a top-of-rack that is coupled to the first backplane via the first backplane network switch, the top-of-rack being coupled to the second backplane via the first backplane network switch and the second backplane network switch.

9. The system of claim 8 , wherein the top-of-rack comprises a top-of-rack connector that is coupled to the first backplane via the first backplane top connector.

10. The system of claim 9 , wherein the top-of-rack further comprises at least one additional top-of-rack connector and is coupled to a plurality of server racks.

11. The system of claim 8 , wherein each of the at least one rack module includes a computing sled.

12. The system of claim 8 , wherein the first backplane network switch includes a local area network (LAN) switch integrated circuit (IC).

13. The system of claim 8 , wherein each network port is a local area network (LAN) port or a RJ45 port.

14. A method operated by a rack system, comprising:
receiving first network data from each of a first plurality of rack modules at a first chassis network switch of a first chassis network switch, the first chassis network switch coupled to each of the plurality of rack modules;
receiving the first network data from the first chassis network switch at a first backplane network switch, wherein the first back plane network switch is coupled to each of a first plurality of chassis via a first chassis network switch, each of the first plurality of chassis comprising the first plurality of rack modules;
receiving second network data from a second backplane network switch at the first backplane network switch, wherein the second back plane network switch is coupled to each of a second plurality of chassis via a second chassis network switch, each of the second plurality of chassis comprising a second plurality of rack modules, the second chassis network switch coupled to each of the second plurality of rack modules;
receiving first network data from the first backplane network switch at a top-of-rack; and
receiving the second network data from the first backplane network switch at the top-of-rack, the top-of-rack being coupled to the second backplane network switch via the first backplane network switch.
