Automated Data Migration
• Automatically migrate data according to user-defined
– Extends HSM capabilities with policy engine
– Might also include discovery and classification tools
Automated Data Migration (ADM) tools automate the migration of data from
one storage class to another based on user-defined policies. ADM solutions
are a combination of intelligent storage resource management (SRM) and
HSM was designed to automate data migration for archival purposes,
and it is access-driven
how frequently the data is accessed determines where it is stored.
ADM solutions migrate data across storage resources based on user-
defined criteria, not just age or frequency of usage.
ADM solutions are designed to classify different tiers of storage, not just online
versus nearline versus offline storage. Ultimately, HSM and ADM solutions are
similar in terms of the underlying technology, but ADM solutions are “value-
driven” rather than “age-driven”.
