Abstract

A system and method to perform data management operations in a data management system assigns the data management request to one or more available data management resources. If the data management request fails, at least one data management resource at least partially responsible for the failure is determined, as is a category associated with the one data management resource at least partially responsible for the failure. Other data management requests are identified in a list of data management requests that request data management resources having the same category and the list of data management requests is updated to indicate that the data management system should not perform the other identified data management requests.

Claims

1. A non-transitory computer-readable medium encoded with instructions for controlling a computer system to perform a set of data management requests, by a method comprising:

receiving a list of data management requests to be performed by a data management system,

wherein each data management request is to perform at least one data management operation using data management resources of the data management system;

attempting to perform a data management request from the list of data management requests by assigning the data management request to one or more available data management resources;

if the data management request fails,

determining at least one data management resource at least partially responsible for the failure;

determining a category associated with the one data management resource at least partially responsible for the failure,

wherein data management resources are associated with categories;

identifying other data management requests in the list of data management requests that request data management resources having the same category; and

updating the received list of data management requests to indicate that the data management system should not perform the other identified data management requests.

2. The computer-readable medium of claim 1 wherein a category is created for each common resource that is likely to be critical to the performance of a data management request.

3. The computer-readable medium of claim 1 wherein identifying other data management requests in the list of data management requests comprises determining a likeness factor among the data management requests that use similar data management resources, and treating the categories as the same when the likeness factor exceeds a threshold.

4. The computer-readable medium of claim 1 wherein identifying other data management requests in the list of data management requests comprises determining whether the data management request failed because of a common resource, and when the data management request fails because of a common resource, then identifying other data management requests in the list of data management requests that request data management resources having the same category as the common resource.

5. The computer-readable medium of claim 1 wherein identifying other data management requests in the list of data management requests comprises determining whether the data management request failed because of a unique resource, and when the data management request fails because of a unique resource, then not identifying other data management requests in the list of data management requests that request data management resources having the same category as on the unique resource.

6. A method to perform a set of data management operations by a computing device in a data management system, the method comprising:

requesting a data management operation, from a data structure representing multiple data management requests, be performed within a time window,

wherein the requesting includes assigning the data management operation to one or more available data management resources;

if the data management request fails,

determining at least one data management resource at least partially responsible for the failure;

determining a category associated with the one data management resource at least partially responsible for the failure,

wherein each data management resource is associated with one of multiple categories;

identifying other data management requests in the data structure of data management requests that request data management resources having the same category; and

updating the received data structure of data management requests to indicate that a data management system should not perform the other identified data management requests.

7. The method of claim 6 wherein a category is created for each common resource that is likely to be critical to the performance of a data management request.

8. The method of claim 6 wherein identifying other data management requests in the data structure of data management requests comprises determining a likeness factor among the data management requests that use similar data management resources, and treating the categories as the same when the likeness factor exceeds a threshold.

9. The method of claim 6 wherein identifying other data management requests in the data structure of data management requests comprises determining whether the data management request failed because of a common resource, and when the data management request fails because of a common resource, then identifying other data management requests in the data structure of data management requests that request data management resources having the same category as the common resource.

10. The method of claim 6 wherein identifying other data management requests in the data structure of data management requests comprises determining whether the data management request failed because of a unique resource, and when the data management request fails because of a unique resource, then not identifying other data management requests in the data structure of data management requests that request data management resources having the same category as on the unique resource.

11. The method of claim 6 further comprising creating a grid or table representing a set of resources needed by data storage requests to thereby match up a set of resources that can best satisfy a request, wherein a physical data storage resource close geographically or by network proximity to a client computer is selected.

12. A system configured to perform a set of data management operations in a data management system, the system comprising:

at least one processor;

at least one memory, coupled to the processor, and storing instructions to be performed by the processor, the instructions including;

requesting a data management operation, from a data structure representing multiple data management requests, be performed within a time window,

wherein the requesting includes assigning the data management operation to one or more available data management resources;

if the data management request fails,

determining at least one data management resource at least partially responsible for the failure;

determining a category associated with the one data management resource at least partially responsible for the failure,

wherein each data management resource is associated with one of multiple categories;

identifying other data management requests in the data structure of data management requests that request data management resources having the same category; and

updating the received data structure of data management requests to indicate that a data management system should not perform the other identified data management requests.

13. The system of claim 12 wherein a category is created for each common resource that is likely to be critical to the performance of a data management request.

14. The system of claim 12 wherein identifying other data management requests in the data structure of data management requests comprises determining a likeness factor among the data management requests that use similar data management resources, and treating the categories as the same when the likeness factor exceeds a threshold.

15. The system of claim 12 wherein identifying other data management requests in the data structure of data management requests comprises determining whether the data management request failed because of a common resource, and when the data management request fails because of a common resource, then identifying other data management requests in the data structure of data management requests that request data management resources having the same category as the common resource.

16. The system of claim 12 wherein identifying other data management requests in the data structure of data management requests comprises determining whether the data management request failed because of a unique resource, and when the data management request fails because of a unique resource, then not identifying other data management requests in the data structure of data management requests that request data management resources having the same category as on the unique resource.

17. The system of claim 12 further comprising creating a grid or table representing a set of resources needed by data storage requests to thereby match up a set of resources that can best satisfy a request, wherein a physical data storage resource close geographically or by network proximity to a client computer is selected.
