Abstract: A method for storing data in a system that includes a plurality of storage devices, the method that includes obtaining object usage data from the plurality of storage devices, determining, using the object usage data, object clusters, where at least one object cluster of the object clusters includes at least two objects that are associated based on access patterns, migrate a first object, of the two objects, from a first storage device of the plurality of storage devices to a second storage device of the plurality of storage devices.

Abstract: Techniques for processing I/O operations may include: receiving a write I/O operation that writes first data to a target logical address in a logical address range, wherein physical storage is currently unallocated for the target logical address; selecting a first storage tier from which to allocate first physical storage for storing the first data, wherein said selecting uses first I/O access information characterizing I/O activity of a first logical region and performance and capability characteristics of storage tiers to select the first storage tier; allocating first physical storage from the first storage tier; and storing the first data in the first physical storage. The target logical address may be located in the first logical region. The target logical address may alternatively be located in another logical region predicted, based on temporal trends and application profile information, to include the target logical address at a future point in time.

Abstract: Techniques for data storage optimization processing that may include: receiving I/O access information characterizing observed I/O operations directed to a logical address space; analyzing the I/O access information to identify a predicted I/O access distribution expected for the plurality of logical regions of the logical address space at multiple points in time; determining a placement plan specifying placement of data portions of the plurality of logical regions among a plurality of storage tiers; and performing, in accordance with the placement plan, at least one data movement that moves at least a first data portion of a first of the plurality of logical regions from a first of the plurality of storage tiers to a second of the plurality of storage tiers.
