Data center switch
View Patent ↗A method of transferring data in a network is provided. Data is received at a sub-switch of a first bundled switch having a plurality of sub-switches, the sub-switch being configured to only couple to connections external to the first bundled switch. The method also includes transferring the data from the first bundled switch using a multi-lane cable coupled to a second bundled switch, a first end of the multi-lane cable coupled to a sub-switch in the first bundled switch and a second end of the multi-lane cable coupled to at least two sub-switches in the second bundled switch.
1. A bundled switch, comprising:
a plurality of sub-switches having ports, wherein one of the plurality of sub-switches is configured to couple to a multi-lane cable having a first lane and a second lane,
wherein the multi-lane cable is coupled to a second bundled switch having a second plurality of sub-switches and external to the bundled switch, and
wherein the first lane is coupled to a first sub-switch in the second plurality of sub-switches and the second lane is coupled to a second sub-switch in the second plurality of sub-switches.
2. The bundled switch of claim 1 , wherein a number of lanes in the multi-lane cable corresponds to a number of sub-switches in the plurality of sub-switches.
3. The bundled switch of claim 1 , wherein a number of lanes in the multi-lane cable is a multiple of a number of sub-switches in the plurality of sub-switches.
4. The bundled switch of claim 1 , wherein the sub-switches have P ports, and each of the P ports of one of the sub-switches is configured to be coupled to respective ones of P transmission lanes of the multi-lane cable.
5. The bundled switch of claim 1 , wherein a network interface is configurable for both a direct mode and a striped mode.
6. The bundled switch of claim 1 , wherein the bundled switch is a stamped switch.
7. The bundled switch of claim 1 , further comprising a routing manager.
8. The bundled switch of claim 7 , wherein the routing manager is a routing processor associated with the one of the plurality of sub-switches.
9. The bundled switch of claim 8 , wherein the routing processor is configured to manage routing for the one of the plurality of sub-switches with which it is associated.
10. The bundled switch of claim 9 , wherein the routing processor is configured to manage routing in a process isolated from routing management processes of other sub-switches in the bundled switch.
11. The bundled switch of claim 8 , wherein the routing processor is a primary routing processor configured to manage routing processors associated with other sub-switches.
12. The bundled switch of claim 7 , wherein the routing manager comprises a control plane processor configured to manage routing for at least two of the plurality of sub-switches.
13. The bundled switch of claim 12 , wherein the control plane processor is configured to independently manage routing for the sub-switches.
14. The bundled switch of claim 12 , wherein the control plane processor is configured to use a hypervisor to independently manage the sub-switches.
15. A method, comprising:
coupling one of a plurality of sub-switches having ports in a first bundled switch to a multi-lane cable having a first lane and a second lane;
coupling the multi-lane cable to a second bundled switch having a second plurality of sub-switches and external to the first bundled switch, wherein the first lane is coupled to a first sub-switch in the second plurality of sub-switches and the second lane is coupled to a second sub-switch in the second plurality of sub-switches; and
routing data between the one of the plurality of sub-switches and the second bundled switch.
16. The method of claim 15 , wherein a number of lanes in the multi-lane cable corresponds to a number of sub-switches in the plurality of sub-switches of the first bundled switch.
17. The method of claim 15 , wherein a number of lanes in the multi-lane cable is a multiple of a number of sub-switches in the plurality of sub-switches.
18. The method of claim 15 , wherein the sub-switches have P ports, and a P port of one of the sub-switches is configured to be coupled to a P transmission lane of the multi-lane cable.
19. A bundled switch, comprising:
a plurality of sub-switches having ports, wherein one of the plurality of sub-switches is configured to couple to a multi-lane cable having a first lane and a second lane, wherein the first lane is coupled to a first sub-switch in a second plurality of sub-switches of a second bundled switch and the second lane is coupled to a second sub-switch in the second plurality of sub-switches of the second bundled switch; and
a processor coupled to the one of the plurality of sub-switches, wherein the processor routes data between the one of the plurality of sub-switches and the second bundled switch.
