Abstract

Systems, devices, and methods for disaggregating networking components are provided. An example networking system includes a first network domain including a first networking chassis. The first networking chassis includes a first disaggregated server device supported by the first networking chassis including a first central processing unit (CPU); and a first graphics processing unit (GPU) coupled with the first CPU. The first CPU and the first GPU are configured to perform one or more computing operations associated with the first networking chassis. The networking system further includes a second network domain comprising a plurality of rack switches operably coupled with at least the first networking chassis.

First claim

1 . A networking system comprising:
a first network domain comprising at least:
a first networking chassis comprising:
a first disaggregated server device supported by the first networking chassis, the first disaggregated server device comprising:
a first central processing unit (CPU);
a first graphics processing unit (GPU) coupled with the first CPU, wherein the first CPU and the first GPU are configured to perform one or more computing operations associated with the first networking chassis; and

a second network domain comprising a plurality of rack switches operably coupled with at least the first networking chassis.

2 . The networking system according to claim 1 , wherein the first GPU of the first disaggregated server device is isolated on the first disaggregated server device.

3 . The networking system according to claim 1 , wherein the first GPU is the only GPU on the first disaggregated server device.

4 . The networking system according to claim 1 , wherein the first GPU is supported on the first disaggregated server device in the absence of other GPUs on the first disaggregated server device.

5 . The networking system according to claim 1 , wherein the first networking chassis further comprises:
a first insertable switch module operably coupled with the first disaggregated server device comprising:
one or more first switching chipsets; and
a first fabric management controller operably coupled with the one or more first switching chipsets, wherein the first insertable switch module is configured to at least partially control data transmission associated with the first disaggregated server device.

6 . The networking system according to claim 5 , wherein the first insertable switch module is operably coupled with at least one of the plurality of rack switches forming the second network domain.

7 . The networking system of claim 1 , wherein the first network domain and the second network domain are operably coupled via one or more optical transceivers and optical communication mediums.

8 . The networking system of claim 1 , wherein at least one of the plurality of rack switches comprises:
one or more switching chipsets; and a fabric management controller operably coupled with the one or more switching chipsets.

9 . The networking system of claim 1 , wherein each of the plurality of rack switches of the second network domain are operably coupled with the first networking chassis.

10 . The networking system of claim 1 , wherein the first network domain comprises a plurality of networking chassis including the first networking chassis and wherein each of the plurality of rack switches are operably coupled with each of the plurality of networking chassis.

11 . The networking system according to claim 1 , wherein the first network domain comprises a plurality of datacenter racks wherein a first datacenter rack comprises at least the first networking chassis.

12 . A method comprising:
providing a first network domain comprising at least:
a first networking chassis comprising:
a first disaggregated server device supported by the first networking chassis, the first disaggregated server device comprising:
a first central processing unit (CPU);
a first graphics processing unit (GPU) coupled with the first CPU, wherein the first CPU and the first GPU are configured to perform one or more computing operations associated with the first networking chassis; and

operably coupling a second network domain comprising a plurality of rack switches with at least the first networking chassis.

13 . The method of claim 12 , wherein the first GPU of the first disaggregated server device is isolated on the first disaggregated server device.

14 . The method of claim 12 , wherein the first GPU is the only GPU on the first disaggregated server device.

15 . The method of claim 12 , wherein the first GPU is supported on the first disaggregated server device in the absence of other GPUs on the first disaggregated server device.

16 . The method of claim 12 , wherein the first networking chassis further comprises:
a first insertable switch module operably coupled with the first disaggregated server device comprising:
one or more first switching chipsets; and
a first fabric management controller operably coupled with the one or more first switching chipsets, wherein the first insertable switch module is configured to at least partially control data transmission associated with the first disaggregated server device.

17 . The method of claim 12 , further comprising operably coupling the first insertable switch module with at least one of the plurality of rack switches forming the second network domain.

18 . The method of claim 12 , further comprising operably coupling each of the plurality of rack switches of the second network domain with the first networking chassis.

19 . The method of claim 12 , wherein the first network domain comprises a plurality of networking chassis including the first networking chassis, the method further comprising operably coupling each of the plurality of rack switches with each of the plurality of networking chassis.

20 . The method of claim 12 , wherein the first network domain comprises a plurality of datacenter racks wherein a first datacenter rack comprises at least the first networking chassis.
