INCREASED PARALLELIZATION EFFICIENCY IN TIERING ENVIRONMENTS

摘要

A computer-implemented method, according to one embodiment, includes: receiving an operation request which corresponds to a given object, identifying multiple block addresses which are associated with the given object, determining whether any one or more of the identified block addresses have a token currently issued thereon, and combining the multiple block addresses to a first set in response to determining that at least one token is currently issued on one or more of the identified block addresses. A first portion of the block addresses determined as having a token currently issued thereon is transitioned to a second set. A remaining portion of the block addresses is also divided into equal chunks. The chunks are allocated in the first set across parallelization units, and the block addresses in the second set are divided into equal chunk. Furthermore, the chunks in the second set are allocated to a dedicated parallelization unit.
