Abstract

A system and method for setting global actions in a data storage system is described. In some examples, the system determines a policy based on information from the system, and implements that policy to the system. In some examples, the system adds or modifies global filters based on information from the system.

Claims

1. A system of transferring data from a source to a destination, the system comprising:

a server connected to two or more storage modules actively transferring data from the source to the destination, wherein the server;

generates a report related to data transfer performance of the two or more storage modules, wherein the report indicates results of a quantitative comparison of data transfer performances between the two or more storage modules; and

determines a filter to assign based on the generated report, wherein the filter is assigned at least in part at the two or more storage modules; and

a data transfer modification component, wherein the data transfer modification component modifies the active transfer of data from the source to the destination based in part on the assigned filter.

2. The system of claim 1, wherein the report comprises results of a quantitative comparison of job usage between the two or more storage modules.

3. The system of claim 1, wherein the report comprises results of a quantitative comparison of job delay between the two or more storage modules.

4. The system of claim 1, wherein the quantitative comparison relates to queuing theory.

5. The system of claim 1, wherein the quantitative comparison relates to the M/M/1 model of queuing theory.

6. The system of claim 1, wherein the quantitative comparison of data transfer performances between the two or more storage modules compares a number of jobs at each storage module with a number of storage modules.

7. A system for defining a filter policy in a hierarchical data storage system, the system comprising:

two or more data storage resources, wherein the data storage resources comprise;

a first storage cell that performs a first number of data storage jobs during a data storage operation, wherein a storage cell is configured to transfer data from a source to a destination; and

a second storage cell, different from the first storage cell, that performs a second number of data storage jobs during the data storage operation; and

a server configured to assign a filter policy to the first storage cell and the second storage cell, wherein the server comprises;

a comparison component that compares the performed first number of jobs to the performed second number of jobs; and

a filter assignment component that assigns the filter policy to the first storage cell and the second storage cell based on the comparison.

8. The system of claim 7, wherein assigning the filter policy includes assigning a global filter policy that applies to all storage cells within the hierarchical data storage system.

9. The system of claim 7, wherein assigning the filter policy includes assigning a first filter policy that applies to the first storage cell and assigning a second filter policy at least partially different than the first filter policy to the second storage cell.

10. The system of claim 7, further comprising:

an interface component, wherein the interface component presents the assigned filter policy to an administrator of the hierarchical data storage system.
