Compute node and method of setting up a cloud cluster
View Patent ↗A method of setting up a cloud cluster is disclosed as providing at least one compute node with a baseboard management controller (BMC), the BMC of the compute node receiving secured information and using the secured information to establish communication with a cloud controller. Upon establishing the communication, the compute node then receives a cloud operating system (OS) image from the cloud controller via the BMC of the compute node. Finally, the cloud OS image is written to a host system in the compute node. A compute node is also disclosed.
1. A method of setting up a cloud cluster, including:
receiving secured information by a baseboard management controller (BMC) of a compute node, wherein the secured information is generated by a cloud controller, and wherein the BMC uses the secured information to establish communication with the cloud controller;
upon the establishment of the communication between the BMC and the cloud controller, receiving, by the compute node, a cloud operating system (OS) image via the BMC from the cloud controller; and
writing the cloud OS image to a host system in the compute node.
2. The method according to claim 1 , further including the BMC retrieving a cloud configuration from the cloud controller and simulating a universal serial bus (USB) configuration drive to the compute node.
3. The method according to claim 2 , further including the compute node booting up and reading the cloud configuration in the USB configuration drive.
4. The method according to claim 3 , further including the compute node registering with the cloud controller.
5. The method according to claim 1 , wherein the secured information includes at least the IP address of the cloud controller.
6. The method according to claim 1 , further including the BMC authenticating with the cloud controller.
7. The method according to claim 1 , further comprising a provisioning manager writing the cloud OS image to the host system in the compute node.
8. The method according to claim 2 , further including signing the secured information, the cloud OS image, and the cloud configuration prior to transfer to the compute node.
9. The method according to claim 8 , wherein the cloud controller signs the secured information, the cloud OS image, and the cloud configuration prior to transfer to the compute node.
10. The method according to claim 1 , wherein the BMC communicates with the cloud controller based on asymmetric encryption.
11. The method according to claim 10 , wherein the secured information, the cloud OS image, and the cloud configuration is signed by the cloud controller using a private key.
12. The method according to claim 11 , wherein the compute node decrypts the signed secured information, the signed cloud OS image, and the signed cloud configuration using a public key.
13. The method according to claim 12 , wherein the BMC of the compute node decrypts the signed secured information, the signed cloud OS image and the signed cloud configuration by the public key.
14. A compute node including:
a baseboard management controller (BMC), and
a host system,
wherein the BMC is configured to receive secured information and to use the secured information to establish communication with a cloud controller,
wherein the compute node is configured, upon establishment of the communication between the BMC and the cloud controller, to receive a cloud operating system (OS) image via the BMC from the cloud controller, and
wherein the host system is configured to be written with the cloud OS image.
15. A compute node according to claim 14 , wherein the BMC is configured to receive a cloud configuration from the cloud controller and to simulate a universal serial bus (USB) configuration drive to the compute node.
16. A compute node according to claim 15 , wherein the compute node is configured to boot up and read the cloud configuration in the USB configuration drive, and to register with the cloud controller.
17. A compute node according to claim 14 , wherein the BMC is configured to authenticate with the cloud controller.
18. A compute node according to claim 14 , wherein the BMC is configured to communicate with the cloud controller based on asymmetric encryption.
19. A compute node according to claim 14 , wherein the BMC is configured to decrypt a signed secured information, a signed cloud OS image and a signed cloud configuration by a public key.
