System and method for analyzing application maximum parallel clone sessions for storage devices
One example method includes identifying one or more source storages and a respective available stream count for each source storage, identifying one or more target storages and a respective available stream count for each target storage, negotiating a maximum stream count for a combination of storages that includes the source storages and the target storages, in which the negotiation of the maximum stream count is based on: (i) the respective available stream counts for each source storage; and (ii) the respective available stream counts for each target storage, and the negotiation of the maximum stream count comprises comparing each source storage available stream count to a respective available stream count of each of target storages, and the comparison is performed in ascending order of the respective available stream counts of the source storages, and creating parallel cloning sessions based on the negotiated maximum stream count.
1. A method, comprising:
identifying one or more source storages and a respective available stream count for each source storage;
identifying one or more target storages and a respective available stream count for each target storage;
negotiating a maximum stream count for a combination of storages that includes the one or more source storages and the one or more target storages, in which the negotiation of the maximum stream count is based on: (i) the respective available stream counts for each source storage; and (ii) the respective available stream counts for each target storage, and the negotiation of the maximum stream count comprises comparing each source storage available stream count to a respective available stream count of each of the one or more target storages, and the comparison is performed in ascending order of the respective available stream counts of the one or more source storages;
creating, with a backup application, parallel cloning sessions based on the negotiated maximum stream count, wherein the parallel cloning sessions are created without the use of a default, or a manual, specification of a session count, and the parallel cloning sessions are created in such a way as to make optimal use, by the parallel cloning sessions, of the source storages and target storages without overutilizing the source storages and target storages; and
copying one or more savesets from the one or more source storages to the one or more target storages, wherein the copying is performed using the parallel cloning sessions.
2. The method as recited in claim 1 , wherein one of the source storages and/or one of the target storages has a number of available streams that is less than a supportable maximum number of streams.
3. The method as recited in claim 1 , wherein negotiation of the maximum stream count is based on either: a combination of storages that includes one source storage and multiple target storages; or a combination of storages that includes multiple source storages and multiple target storages.
4. The method as recited in claim 1 , further comprising performing the following after the one or more source storages and the one or more target storages have been identified:
sorting, for each source storage, the respective available streams of that source storage; and
sorting for each target storage, the respective available streams of that target storage.
5. The method as recited in claim 1 , wherein multiple target storages are identified, and only a single source storage is identified, and the available source storage streams are divided between the target storages based on the availability of target storage streams at each of the target storages.
6. The method as recited in claim 1 , wherein the method is performed iteratively until one of the following is true: a number of available source storage streams is zero; or, a number of available target storage streams is zero.
7. The method as recited in claim 1 , wherein the number of source storages is the same as the number of target storages.
8. The method as recited in claim 1 , wherein the number of identified source storages is different from the number of identified target storages.
9. The method as recited in claim 1 , wherein the number of identified source storages is less than the number of identified target storages.
10. The method as recited in claim 1 , further comprising subtracting the number of created parallel cloning sessions from the smaller of remaining available source storage streams or remaining available target storage streams.
11. A non-transitory storage medium having stored therein instructions which are executable by one or more hardware processors to perform operations comprising:
identifying one or more source storages and a respective available stream count for each source storage;
identifying one or more target storages and a respective available stream count for each target storage;
negotiating a maximum stream count for a combination of storages that includes the one or more source storages and the one or more target storages, in which the negotiation of the maximum stream count is based on: (i) the respective available stream counts for each source storage; and (ii) the respective available stream counts for each target storage, and the negotiation of the maximum stream count comprises comparing each source storage available stream count to a respective available stream count of each of the one or more target storages, and the comparison is performed in ascending order of the respective available stream counts of the one or more source storages;
creating, with a backup application, parallel cloning sessions based on the negotiated maximum stream count, wherein the parallel cloning sessions are created without the use of a default, or a manual, specification of a session count, and the parallel cloning sessions are created in such a way as to make optimal use, by the parallel cloning sessions, of the source storages and target storages without overutilizing the source storages and target storages; and
copying one or more savesets from the one or more source storages to the one or more target storages, wherein the copying is performed using the parallel cloning sessions.
12. The non-transitory storage medium as recited in claim 11 , wherein one of the source storages and/or one of the target storages has a number of available streams that is less than a supportable maximum number of streams.
13. The non-transitory storage medium as recited in claim 11 , wherein negotiation of the maximum stream count is based on either: a combination of storages that includes one source storage and multiple target storages; or a combination of storages that includes multiple source storages and multiple target storages.
14. The non-transitory storage medium as recited in claim 11 , wherein the operations further comprise performing the following after the one or more source storages and the one or more target storages have been identified:
sorting, for each source storage, the respective available streams of that source storage; and
sorting for each target storage, the respective available streams of that target storage.
15. The non-transitory storage medium as recited in claim 11 , wherein multiple target storages are identified, and only a single source storage is identified, and the available source storage streams are divided between the target storages based on the availability of target storage streams at each of the target storages.
16. The non-transitory storage medium as recited in claim 11 , wherein the operations are performed iteratively until one of the following is true: a number of available source storage streams is zero; or, a number of available target storage streams is zero.
17. The non-transitory storage medium as recited in claim 11 , wherein the number of source storages is the same as the number of target storages.
18. The non-transitory storage medium as recited in claim 11 , wherein the number of identified source storages is different from the number of identified target storages.
19. The non-transitory storage medium as recited in claim 11 , wherein the number of identified source storages is less than the number of identified target storages.
20. The non-transitory storage medium as recited in claim 11 , wherein the operations further comprise subtracting the number of created parallel cloning sessions from the smaller of remaining available source storage streams or remaining available target storage streams.
