Abstract

Various exemplary embodiments relate to a method and related network node including one or more of the following: detecting, by a resource allocation device, a failure of server hardware; identifying a first agent device that is configured to utilize the server hardware; and taking at least one action to effect a reconfiguration of the first agent device in response to the server hardware failure. Various embodiments additionally include one or more of the following: identifying a second agent device that is configured to utilize the server hardware; and taking at least one action to effect a reconfiguration of the second agent device in response to the server hardware failure. Various embodiments additionally include one or more of the following: receiving, by the resource allocation device from a second agent device, an indication of the failure of server hardware, wherein the second agent device is different from the first agent device.

Claims

1. A method performed by a resource allocation device that allocates server resources for mitigating the effects of server hardware failure, the method comprising:

detecting, by the resource allocation device, a failure of server hardware;

identifying a first agent device that is configured to utilize the server hardware; and

taking at least one action to effect a reconfiguration of the first agent device in response to the server hardware failure.

2. The method of claim 1, further comprising:

identifying a second agent device that is configured to utilize the server hardware; and

taking at least one action to effect a reconfiguration of the second agent device in response to the server hardware failure.

3. The method of claim 1, wherein the step of detecting a failure of server hardware comprises:

receiving, by the resource allocation device from a second agent device, an indication of the failure of server hardware, wherein the second agent device is different from the first agent device.

4. The method of claim 1, wherein the at least one action comprises instructing a second resource allocation device to allocate server hardware resources for the first agent device.

5. The method of claim 4, wherein the step of instructing the second resource allocation device comprises transmitting an instruction message to the second resource allocation device via the Internet.

6. The method of claim 1, wherein the at least one action comprises suspending an operation of the first agent device.

7. The method of claim 1, wherein the at least one action comprises simulating an error for the first agent device.

8. The method of claim 7, wherein the step of simulating an error for the first agent device comprises transmitting, via the Internet, an error message to a device associated with the agent device.

9. A resource allocation device comprising:

an agent device definition storage that stores a first agent device definition, wherein the first agent device definition identifies a first agent device and an associated server hardware resource;

a hardware failure detector configured to detect a failure of the server hardware resource; and

an agent device protection module configured to;

identify, based on the agent device definition, the first agent device as an agent device that is configured to utilize the server hardware resource, and

take at least one action to effect a reconfiguration of the first agent device in response to the server hardware failure.

10. The resource allocation device of claim 9, wherein:

the agent device definition storage stores a second agent device definition, wherein the second agent device definition identifies a second agent device and an associated server hardware resource; and

the agent device protection module is further configured to;

identify a second agent device as an agent device that is configured to utilize the server hardware resource; and

take at least one action to effect a reconfiguration of the second agent device in response to the server hardware failure.

11. The resource allocation device of claim 9, wherein, in detecting a failure of server hardware, the hardware failure detector is configured to:

receive, by the hardware failure detector from a second agent device, an indication of the failure of server hardware, wherein the second agent device is different from the first agent device.

12. The resource allocation device of claim 9, wherein the at least one action comprises instructing a second resource allocation device to allocate server hardware resources for the first agent device.

13. The resource allocation device of claim 11, wherein the at least one action further comprises transmitting, to the second resource allocation device, a device image associated with the first agent device.

14. The resource allocation device of claim 11, wherein, in instructing the second resource allocation device, the agent device protection module transmits an instruction message to the second resource allocation device via the Internet.

15. The resource allocation device of claim 9, wherein the at least one action comprises suspending an operation of the first agent device.

16. The resource allocation device of claim 9, wherein the at least one action comprises simulating an error for the first agent device.

17. A tangible and non-transitory machine-readable storage medium encoded with instructions for mitigating the effects of server hardware failure, the tangible and non-transitory machine-readable storage medium comprising:

instructions for detecting, by the resource allocation device, a failure of server hardware;

instructions for identifying a first agent device that is configured to utilize the server hardware; and

instructions for taking at least one action to effect a reconfiguration of the first agent device in response to the server hardware failure.

18. The tangible and non-transitory machine-readable storage medium of claim 17, further comprising:

instructions for identifying a second agent device that is configured to utilize the server hardware; and

instructions for taking at least one action to effect a reconfiguration of the second agent device in response to the server hardware failure.

19. The tangible and non-transitory machine-readable storage medium of claim 17, wherein the instructions for detecting a failure of server hardware comprise:

instructions for receiving, by the resource allocation device from a second agent device, an indication of the failure of server hardware, wherein the second agent device is different from the first agent device.

20. The tangible and non-transitory machine-readable storage medium of claim 17, wherein the at least one action comprises instructions for instructing a second resource allocation device to allocate server hardware resources for the first agent device.

21. The tangible and non-transitory machine-readable storage medium of claim 20, wherein the instructions for instructing the second resource allocation device comprise instructions for transmitting an instruction message to the second resource allocation device via the Internet.

22. The tangible and non-transitory machine-readable storage medium of claim 17, wherein the at least one action comprises instructions for suspending an operation of the first agent device.

23. The tangible and non-transitory machine-readable storage medium of claim 17, wherein the at least one action comprises instructions for simulating an error for the first agent device.

24. A method performed by a hypervisor for mitigating the effects of hardware failure, the method comprising;

detecting, by the hypervisor, a failure of server hardware;

identifying a first virtual machine that is configured to utilize the server hardware; and
