Abstract

Embodiments relate to systems and methods for replicating data from a primary resource to a secondary resource within a storage network based on resource attributes. In particular, a user can specify a policy framework comprising one or more count selections and one or more attributes. A policy generation module can determine candidate resources that match the policy framework, and order the candidate resources based on one or more factors. The policy generation module can generate a replication policy based on the ordered resources and replicate the data according to the replication policy.

First claim

What is claimed is:

1. A method comprising:
detecting a data object to be replicated;
receiving a number representing a quantity of a plurality of resources on which the data object is to be replicated and receiving a plurality of attributes associated with the plurality of resources, wherein the plurality of attributes comprise a programming language supported by the plurality of resources;
determining a plurality of candidate resources in view of the plurality of attributes;
ordering the plurality of candidate resources in view of a factor;
selecting a subset of the plurality of candidate resources in view of the ordering of the plurality of candidate resources and the received number;
generating, by a hardware processor, a replication policy for the data object in view of the received number and the plurality of attributes; and
replicating, according to the replication policy, the data object on the subset of candidate resources.

2. The method of claim 1 , further comprising ordering the plurality of candidate resources in view of a cost factor,
wherein generating the replication policy comprises:
selecting the quantity of the subset of candidate resources; and
entering the quantity of the subset of candidate resources into a policy framework.

3. The method of claim 1 , further comprising:
determining the replication policy for the data object in view of the ordering of the plurality of candidate resources.

4. The method of claim 3 , wherein the factor is specified by a policy framework.

5. The method of claim 1 , further comprising:
providing a user interface; and
receiving the number indicating the quantity of the plurality of resources and the plurality of attributes associated with the plurality of resources via the user interface.

6. The method of claim 1 , further comprising:
dynamically determining the quantity of the plurality of resources and the plurality of attributes associated with the plurality of resources.

7. The method of claim 2 , wherein the policy framework further specifies that each of the plurality of resources is associated with a unique value for each of the plurality of attributes.

8. The method of claim 1 , further comprising:
generating a notification indicating the replication policy; and
providing the notification to a user.

9. A system comprising:
an interface to a plurality of resources; and
a hardware processor, to communicate with the plurality of resources via the interface, the hardware processor to:
detect a data object to be replicated;
receive a number representing a quantity of the plurality of resources on which the data object is to be replicated and receiving a plurality of attributes associated with the plurality of resources, wherein the plurality of attributes comprise a programming language supported by the plurality of resources;
determine a plurality of candidate resources in view of the plurality of attributes;
order the plurality of candidate resources in view of a factor;
select a subset of the plurality of candidate resources in view of the ordering of the plurality of candidate resources and the received number;
generate a replication policy for the data object in view of the selected candidate resources received number and the plurality of attributes; and
replicate, according to the replication policy, the data object on the subset of candidate resources.

10. The system of claim 9 , wherein the hardware processor is further to order the plurality of candidate resources in view of a cost factor, and wherein to generate the replication policy, the hardware processor is to:
select the quantity of the subset of candidate resources; and
enter the quantity of the subset of candidate resources into a policy framework.

11. The system of claim 9 , wherein the hardware processor is further to:
determine the replication policy for the data object in view of the ordering of the plurality of candidate resources.

12. The system of claim 11 , wherein the factor is specified by a policy framework.

13. The system of claim 9 , wherein the hardware processor is further to:
provide a user interface; and
receive the number representing the quantity of the plurality of resources and the plurality of attributes associated with the plurality of resources via the user interface.

14. The system of claim 9 , wherein the hardware processor is further to:
dynamically determine the quantity of the plurality of resources and the plurality of attributes associated with the plurality of resources.

15. The system of claim 10 , wherein the policy framework further specifies that each of the plurality of resources is associated with a unique value for each of the plurality of attributes.

16. The system of claim 9 , wherein the hardware processor is further to:
generate a notification indicating the replication policy; and
provide the notification to a user.
