Abstract
A technique for managing storage tiering in a data storage apparatus operates at a fine level of granularity in response to write requests as blocks are allocated for writing. As write requests arrive or are otherwise processed by the data storage apparatus, the data storage apparatus identifies a quality of service to be provided for satisfying each write request and allocates a set of blocks from storage devices of storage tiers that provide the identified quality of service. The data storage apparatus may then store the information specified in the write request in the newly allocated blocks.
