Patent ID: 8904144

Claim:
A method for determining at risk indexes of storage capacity of a plurality of storage containers in a data storage system, the method comprising: determining, by a storage management computing device, available allocated capacities of the plurality of storage containers; converting, by the storage management computing device, the available allocated capacities to respective allocated capacities in a predetermined time period by dividing each available allocated capacity by a growth rate of each respective one of the plurality of storage containers; determining, by the storage management computing device, available unallocated capacities of the plurality storage containers; converting, by the storage management computing device, the available unallocated capacities to respective unallocated capacities in the predetermined time period by dividing each available unallocated capacity by a growth rate of all storage containers sharing a parent storage container with the respective storage container; and determining, by the storage management computing device, the at risk indexes from a sum of the respective allocated capacities in the predetermined time period and the respective unallocated capacities in the predetermined time period, the at risk indexes indicating which the plurality of storage containers are at risk of running out of storage space.
