First claim

What is claimed is:

1. A computer implemented method for automating creation of virtual storage pools within software-defined storage, the method comprising:
receiving a set of physical storage resources that is enabled to have different storage capabilities, wherein each of the physical storage resources in the set of physical storage resources with different capabilities is represented as a physical storage multi-dimensional capability vector;
receiving a set of applications, wherein each application of the set of applications is enabled to require a different storage capability and is comprised of a different application type;
arranging the set of applications into classes of applications according to corresponding application types and assigning a priority level to each of the classes of applications, wherein each of the applications in the set of applications enabled to have a different physical storage requirement and application type is represented, following the arranging, as a multi-dimensional application requirement vector, wherein the dimensions in the multi-dimensional application requirement vector represent corresponding physical storage requirements, application type, and associated priority level;
finding most frequently preferred physical storage requirements from the multi-dimensional application requirement vectors;
identifying a number of virtual storage pools based on the set of applications, wherein the virtual storage pools are represented as a virtual storage pool multi-dimensional capability vector for a grouping of the physical storage resources;
clustering at least some of the set of physical storage resources into the number of identified virtual storage pools; and
processing the physical storage multi-dimensional capability vector, the virtual storage pool multi-dimensional capability vector, and the multi-dimensional application requirement vector to organize the physical storage resources managed by the software-defined storage into the virtual storage pools for meeting requirements of workloads of the set of applications;
wherein organizing the physical storage resources into the virtual storage pools is further implemented as a function of the priority levels assigned to the classes of applications.

2. The method of claim 1 , wherein the clustering of the virtual storage pools comprises clustering physical storage resources with similar capability vectors into virtual storage pools according to application workloads.

3. The method of claim 1 , wherein identifying the number of virtual storage pools comprises combining the classes of applications with similar multi-dimensional application requirement vectors to create a corresponding number of virtual storage pools.

4. The method of claim 1 , wherein clustering at least some of the set of physical storage resources into the virtual storage pools comprises calculating similarity between most frequently preferred physical storage requirements for the set of applications.

5. The method of claim 1 , further comprising configuring the virtual storage pools to initialize and be configured before a platform for the software-defined storage is deployed.

6. The method of claim 1 , further comprising configuring the virtual storage pools to initialize and be configured after a platform for the software-defined storage is deployed.

7. The method of claim 1 , wherein the capabilities represented in the physical storage multi-dimensional capability vector include capacity, input/output operations per second, and disaster recovery support.

8. The method of claim 1 , wherein the virtual storage pool multi-dimensional capability vector and the multi-dimensional application requirement vector each share a portion of the same dimensions as the physical storage multi-dimensional capability vector.

9. A computer program product for automating creation of virtual storage pools within software-defined storage, the computer program product comprising:
a non-transitory computer-readable storage medium encoded with computer-executable program code enabling:
