Abstract
In one embodiment, a configuration adviser provides configuration options for a multi-tiered storage system that includes a number of different storage tiers, each of which include storage devices of a particular storage type. Data access information for storage extents to be stored in the storage system are received. Resource information for available storage tiers in the storage system to place the storage extents on are also received. A cost incurred by the storage system for placing each of the storage extents on each of the storage tiers is determined. Each storage extent is assigned to a particular one of the storage tiers that would incur the lowest cost to the storage system for storing the storage extent. For each storage tier, a minimum number of storage devices are selected, within the assigned storage tier, that would satisfy data access and capacity requirements for all storage extents assigned to that tier.
