Data Storage Management refers to the set of business practices and technologies involved in configuring, monitoring and managing data storage devices so as to optimize their utilization and performance as well as secure them from unauthorized access and data loss. Although this is a broad category that includes Data Security and Data Protection via backups and/or replication some of these are broken out into separate categories. Also note that some Data Storage Management software is included by data storage hardware vendors as the default way to manage the storage (E.g. EMC Navisphere) and some is higher level management software that is not hardware vendor specific.
