Abstract
There is disclosed a method for use in managing databases in data storage systems comprising a plurality of nodes. A request is received to provision storage for a specified application intending to use a database. Based on application-awareness, the storage system is provisioned for storing the database in response to receiving the request. Database tables are distributed across the nodes based on a forecasted first I/O profile between application and database. Information is captured in connection with the activity between the application and database. A second I/O profile is determined based on the captured information. The second I/O profile is an actual in-running I/O profile between application and database. The first I/O profile and second I/O profile are compared. The database tables are re-organized on the nodes based on the comparison identifying a discrepancy between first and second I/O profiles such that storage system is rebalanced.
