Real-time analysis for dynamic storage

Abstract

One or more techniques and/or systems are provided for dynamically provisioning logical storage pools of storage devices for applications. For example, a logical storage pool, of one or more storage devices, may be constructed based upon a service level agreement for an application (e.g., an acceptable latency, an expected throughput, etc.). Real-time performance statistics of the logical storage pool may be collected and evaluated against the service level agreement to determine whether a storage device does not satisfy the service level agreement. For example, a latency of a storage device within the logical storage pool may increase overtime as log files and/or other data of the application increase. Accordingly, a new logical storage pool may be automatically and dynamically defined and provisioned for the application to replace the logical storage pool. The new logical storage pool may comprise storage devices expected to satisfy the storage level agreement.

         6 . The method of  claim 5 , the migrating data comprising:

         9 . The method of  claim 2 , comprising:
 identifying an updated SLA for the application;   comparing the real-time performance statistics with the updated SLA to identify a storage device that does not satisfy the updated SLA;   defining a new logical storage pool comprising storage devices that satisfy the updated SLA and a replacement storage device used to replace the storage device that does not satisfy the updated SLA;   migrating data from the storage device that does not satisfy the updated SLA to the replacement storage device; and   provisioning the new logical storage pool for the application.   
     
     
         10 . The method of  claim 3 , the migrating and the provisioning comprising:
 providing a suggestion of the new logical storage pool to an administrator; and   responsive to receiving a new provision command from the administrator in response to the suggestion, performing the migrating and the provisioning.   
     
     
         11 . The method of  claim 3 , the migrating and the provisioning comprising:
