METHOD, APPARATUS AND PROGRAM STORAGE DEVICE FOR PROVIDING AUTOMATIC PERFORMANCE OPTIMIZATION OF VIRTUALIZED STORAGE ALLOCATION WITHIN A VIRTUALIZED STORAGE SUBSYSTEM

摘要

A volume provisioning advisor for managing storage allocation in a plurality of virtual storage subsystems is disclosed. A request for data storage and workload requirements is received from a user. Performance information for storage controllers and managed disks within a virtualization engine is received. Resource groups are defined based on the received performance information and available managed disks, and their utilizations tracked. Resource group performance within the virtualization engine is predicted based on the user workload requirements and existing or historical resource group utilization. Storage is allocated to one or more managed disks within the virtualization engine based on predicted resource group performance.
