Traditional hierarchical storage management (HSM) software wasn’t architected for today’s complex storage environments with multiple storage vendors, different file systems, public cloud, and geographic locations. Today’s sophisticated workflows and the sheer volume of unstructured data requires a deeper insight into the data, its value to the business and the requirements for long-term retention. Modern HSM must support robust policy controls, multi-vendor storage, and dynamic data movement across multi-destinations during the data’s life cycle. Most HSM cannot support these rigorous requirements. And HSM does nothing for data classification, data protection, data verification, data resilience, and data provenance.
HSM has a reliance on hard links called stubs that make moved data appear to reside on primary storage, but intercepts access requests, and retrieves the data from where it actually resides, and rehydrates it back to primary storage. This process adds latency and increase risk of data loss and corruption. Stubs are also brittle. When stubbed data is moved from its storage – file, object, cloud, or tape – to another location the stubs can breaks. The HSM then no longer knows where the data has been moved and it’s orphaned. The stub has a proprietary format for accessing the moved data, so data cannot be accessed with the stub. When primary storage is tech refreshed, stubs can become broken or corrupted.
Symlinks (symbolic links) or HSM agents are not the answer. Symlinks might not rehydrate data but adds redirect latency and can break when primary storage is tech refreshed. HSM agents must be implemented, upgraded, patched, and managed on every physical or virtual server.
Most HSM was designed for a much simpler storage era of single vendor, single source and target storage.
StrongLink Autonomous Data Management – The Modern HSM
StrongLink connects across storage system and dynamically migrates data based on policy to the right storage. StrongLink eliminates the identified HSM problems and does not use stubs, symlinks, or agents. Local, network and cloud storage is presented in a global name space so users maintain a persistent file view based on permissions regardless of where files are stored. StrongLink data movers ensure data is automatically stored on the right storage tier, files are automatically archived to meet life cycle management policy, and user can use any vendor disk, tape or cloud. StrongLink makes sure data is accessible no matter where it resides. Files can be saved in the original path name for archive and business continuity so files can be directly accessed from the storage without dependency on StrongLink. StrongLink enforces data provenance with audit trails. And StrongLink costs less than HSM since it does not license based on capacity.
