SYSTEM, METHOD, AND COMPUTER-READABLE MEDIUM FOR OPTIMIZED DATA STORAGE AND MIGRATION IN A DATABASE SYSTEM

摘要

A system, method, and computer-readable medium that facilitate optimized data storage and migration are provided. Storage device zones are tested and assigned respective speed quality ratings. The frequency with which data is accessed within the system may be periodically monitored and a corresponding access frequency quantifier assigned to the data is updated accordingly. The data access frequency quantifier may be associated with a storage device zone speed quality rating. The association between data access frequency quantifiers and the storage device zone speed quality ratings may be made in a hierarchical association such that quantifiable differentials may be ascertained between a particular access frequency quantifier and a storage device zone speed quality rating. In this manner, when no storage zone having a speed quality rating that is associated with data having a particular access frequency quantifier is available for storage of the data, a storage zone having a speed quality rating more proximate the speed quality rating associated with the access frequency quantifier may be identified for migration of the data for storage thereby.
