Abstract
A system and method for data storage management is disclosed. The method includes determining, by an access tracking component, a quantity of access requests for at least one data block, and determining a quantity of current copies of the data block. The method also includes creating, by a duplication component, at least one additional copy of the data block when the quantity of the access requests exceeds an access request threshold. Additionally, a deduplication component removes at least one current copy of the data block when the quantity of the access requests falls below the access request threshold. The access request threshold can be a threshold number of access requests for the data block, the presence of an input/output bottleneck, or a given length of a read latency when accessing the data block. Further, data coloring techniques can be used to distribute current copies of the data block.
