INCREASING DATA PERFORMANCE BY TRANSFERRING DATA BETWEEN STORAGE TIERS USING WORKLOAD CHARACTERISTICS

摘要

A computer-implemented method includes: receiving one or more suggestions which correspond to placement of data in storage, where the one or more suggestions are based on data workload characteristics. The one or more suggestions are used to identify portions of actual data stored in actual storage which correspond to the one or more suggestions. For each of the identified portions of the actual data stored in the first tier the one or more suggestions is further used to determine whether to transfer the given identified portion of the actual data to the second tier. Moreover in response to determining to transfer at least one of the identified portions of the actual data to the second tier one or more instructions are sent to transfer the at least one of the identified portions of the actual data from the first tier to the second tier.
