Patent ID: 8261018

Claim:
A method for managing a data storage system, said data storage system being coupled to a volume storage pool, the data storage system presenting at least one virtual volume as a storage resource to a host device, the method for managing the data storage system comprising: collecting the volume storage pool occupancy and the virtual volume consumption; trending the volume storage pool occupancy and the virtual volume consumption; defining a threshold value for a rapid increase or surge in volume storage pool occupancy; tracking the rapid increase or surge in volume storage pool occupancy using a segmented regression; generating a notification when the surge in volume storage pool occupancy is at the threshold value; forecasting the volume storage pool occupancy and virtual volume consumption; and recommending at least one action based on the forecasted value of the volume storage pool occupancy and virtual volume consumption wherein the action may be selected from a group comprising: adding extra volume to the volume storage pool; and migrating the data from the volume storage pool to a second volume storage device.
