Abstract

A system and method of provided for automatically update a system'"'"'s software. In one example, the software is updated without requiring user intervention. Further, a system is provided that is capable of performing a software update on a non-PC system, such as a networking device, uninterruptible power supply (UPS), or other system. In another example, a system and method is provided for updating multiple components of a system by a proxy system responsible for downloading and applying updates.

Claims

1. A method for updating software in a system comprising an update server, the update server being adapted to store one or more software updates, the method comprising acts of:

receiving, from the update server, a catalog of updates available from the update server;

determining if at least one available update referenced in the catalog of updates applies to at least one managed device; and

if so, downloading the at least one available update and applying the at least one available update to the at least one managed device.

2. The method according to claim 1, further comprising acts of:

maintaining a local catalog of updates; and

merging the received catalog of updates with the local catalog of updates.

3. The method according to claim 1, wherein the at least one available update comprises an operating system component and a management component, and wherein the act of applying the at least one available update further comprises applying the operating system component to the at least one managed device prior to applying the management component to the at least one managed device.

4. The method according to claim 1, wherein the acts of receiving, determining, downloading and applying are each performed by a secondary server.

5. The method according to claim 1, wherein the act of determining comprises an act of comparing filename information of a file associated with the at least one available update to filename information of a current portion of software associated with the at least one managed device.

6. The method according to claim 1, further comprising an act of sending at least one file to the at least one managed device.

7. The method according to claim 1, further comprising an act of verifying that at least one file associated with the at least one available update is not corrupted, and wherein the act of verifying is performed prior to the act of applying.

8. The method according to claim 7, wherein the acts of verifying and applying are each performed by a secondary server.

9. The method according to claim 4, wherein the secondary server performs one or more updates for a plurality of managed devices.

10. The method according to claim 9, wherein the plurality of managed devices are each components of an Uninterruptible Power Supply (UPS) system, and wherein the secondary server applies the one or more updates to selected components of the UPS system.

11. The method according to claim 1, further comprising an act of determining, on behalf of a plurality of devices, whether an update exists on the update server.

12. The method according to claim 5, wherein the act of comparing filename information of the file associated with the at least one available update to the filename information to the current portion of software of the at least one managed device includes an act of comparing revision level information of the file associated with the at least one available update with revision level information of the current portion of software of the at least one managed device, and determining whether the at least one managed device should be updated based on the comparison.

13. The method according to claim 12, further comprising an act of determining whether the revision level of the at least one available update is a later revision of software as compared to the revision level file associated with the at least one available update to the filename information to the current portion of software of the at least one managed device.

14. The method according to claim 1, wherein the at least one available update comprises an operating system component and a management component, and wherein the act of applying the at least one available update further comprises applying the operating system component to the at least one managed device and applying the management component to at least one of the at least one managed device and a manager of the at least one managed device.

15. The method according to claim 14, wherein the management component is applied to the at least one managed device if the at least one managed device is coupled to a public network.

16. The method according to claim 14, wherein the management component is applied to the manager of the at least one managed device if the at least one managed device is coupled to a private network.

17. The method according to claim 14, wherein the management component is applied to the manager of the at least one managed device if the manager is adapted to apply the at least one available update.

18. The method according to claim 14, wherein the manager is adapted to perform the acts of receiving, determining, downloading, and applying the at least one available update.

19. A system for updating a software component, the system comprising:

an update server configured to store a plurality of available updates; and

a secondary server adapted to manage a plurality of devices, wherein the secondary server is adapted to determine whether any one of the plurality of available updates should be applied to at least one of the plurality of devices, and if so, applying at least one of the plurality of updates to the at least one of the plurality of devices.

20. The system according to claim 19, wherein the at least one of the plurality of updates comprises an operating system component and a management component, and wherein the secondary server is adapted to apply the operating system component to the at least one of the plurality of devices prior to applying the management component to the at least one of the plurality of devices.

21. The system according to claim 19, wherein the secondary server is adapted to compare filename information of a file associated with the at least one available update to filename information of a current portion of software of the at least one of the plurality of devices, and is adapted to determine whether the at least one of the plurality of devices should be updated based on the comparison.

22. The system according to claim 19, wherein the secondary server comprises an interface adapted to receive a catalog of available updates from the update server.

23. The system according to claim 22, wherein the secondary server includes a memory for storing a local catalog of updates, and wherein the secondary server is adapted to merge the received catalog of updates with the local catalog of updates.

24. The system according to claim 19, wherein the secondary server is adapted to compare filename information of a file associated with the at least one of the plurality of updates to filename information of a current portion of software associated with the at least one of the plurality of devices.

25. The system according to claim 19, wherein the secondary server is adapted to load at least one file associated with the at least one of the plurality of updates to the at least one of the plurality of devices.

26. The system according to claim 24, wherein the secondary server is adapted to determine whether the at least one of the plurality of devices should be updated based on the comparison.

27. The system according to claim 19, wherein the plurality of managed devices are each components of an Uninterruptible Power Supply (UPS) system, and wherein the secondary server is adapted to apply the at least one update to one or more selected components of the UPS system.
