Abstract

A multi-chassis server system has several chassis, each including a chassis management controller (CMC) and a blade server with a blade management controller (BMC) and a virtual switch (VS). The first CMC establishes management sessions with the second CMC and the first BMC. The second CMC establishes a management session with the second BMC. A switch path on a virtual switch is provided via a management session to the first CMC and another switch path on another virtual switch is provided via a management session to the second chassis management controller and by another management session to the first CMC. The switch paths are aggregated into a chassis management controller virtual switch on the first chassis management controller.

providing via the first management session the first switch path to the SDN controller;

establishing a second management session between the SDN controller and a first chassis switch of the first chassis;

determining via the second management session a second switch path on the first chassis switch; and

aggregating, by the SDN controller, the first switch path and the second switch path into a chassis management controller virtual switch on the chassis management controller, such that a packet associated with the first switch path can be routed on either of the first switch path or the second switch path.

2. The method of claim 1 , further comprising:

establishing a third management session between the SDN controller and a second baseboard management controller embedded on a second mainboard of a second blade of a second chassis, wherein the second blade includes a second virtual switch and wherein the second chassis is a second rack mounted server system;

determining via the third management session a third switch path on the second virtual switch; and

aggregating, by the SDN controller, the third switch path into the chassis management controller virtual switch.

3. The method of claim 2 , further comprising:

establishing a fourth management session between the SDN controller and a second chassis switch of the second chassis;

determining via the fourth management session a fourth switch path on the second chassis switch; and

aggregating, by the SDN controller, the fourth switch path into the chassis management controller virtual switch.

4. The method of claim 3 , further comprising:

establishing a fifth management session between the SDN controller and a top-of-rack switch associated with the first chassis and the second chassis;

determining via the fifth management session a fifth switch path on the top-of-rack switch; and

aggregating, by the SDN controller, the fifth switch path into the chassis management controller virtual switch.

5. The method of claim 1 , wherein:

the first management session comprises a first virtual local area network; and

the second management session comprises a second virtual local area network.

6. The method of claim 1 , wherein the first management session and the second management session are established on a management network of the first chassis.

7. The method of claim 1 , wherein the first switch path is further determined via an operating system/baseboard management controller passthru on the first blade.

8. The method of claim 1 , wherein the first baseboard management controller operates on an intelligent platform management interface.

9. A method of enabling a virtual switch, the method comprising:

providing a first chassis management controller on a first chassis and a second chassis management controller on a second chassis, wherein the first chassis is a first rack mounted server system and the second chassis is a second rack mounted server;

establishing a first management session between the first chassis management controller and the second chassis management controller;

establishing a second management session between the first chassis management controller and a first baseboard management controller embedded on a first mainboard of a first blade of the first chassis, wherein the first blade includes a first virtual switch;

receiving at the first baseboard management controller a first path on the first virtual switch via a pass through between the first baseboard management controller and the first virtual switch;

providing via the second management session the first switch path to the first chassis management controller;

establishing a third management session between the second chassis management controller and a second baseboard management controller embedded on a second mainboard of a second blade of the second chassis, wherein the second blade includes a second virtual switch;

providing via the third management session a second switch path on the second virtual switch to the second chassis management controller;

providing via the first management session the second switch path to the first chassis management controller; and

aggregating the first switch path and the second switch path into a chassis management controller virtual switch on the first chassis management controller, such that a packet associated with the first switch path can be routed on either of the first switch path or the second switch path.

10. The method of claim 9 , further comprising:

establishing a fourth management session between the first chassis management controller and a first chassis switch of the first chassis;

providing via the fourth management session a third switch path on the first chassis switch to the first chassis management controller; and

aggregating the third switch path into the chassis management controller virtual switch.

11. The method of claim 10 , further comprising:

establishing a fifth management session between the second chassis management controller and a second chassis switch of the second chassis;

providing via the fifth management session a fourth switch path on the second chassis switch to the second chassis management controller;

providing via the first management session the fourth switch path to the first chassis management controller; and

aggregating the fifth switch path into the chassis management controller virtual switch.

12. The method of claim 11 , further comprising:

establishing a sixth management session between the first chassis management controller and a top-of-rack switch associated with the first chassis and the second chassis;

providing via the sixth management session a fifth switch path on the top-of-rack switch to the first chassis management controller; and

aggregating the fifth switch path into the chassis management controller virtual switch.
