HSM is Dead, meet the New HSM

Traditional HSM is Outdated Technology

Traditional hierarchical storage management (HSM) solutions got their start in the 1990s, and weren’t architected for today’s complex storage environments with multiple storage vendors, different file systems, public cloud, and different 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 alternatives to HSMs must support robust policy controls, multi-vendor storage infrastructures, and dynamic data movement during the data’s life cycle. Most HSMs cannot support these rigorous requirements. And those HSMs do nothing for data classification, or advanced metadata features for effective data management.
Traditional HSMs rely on hard links called stubs that make moved data appear to reside on primary storage, but intercepts access requests. This then retrieves the data from where it actually resides, and rehydrates it back to primary storage. This process adds latency and increased risk. Stubs can also be brittle. When stubbed data is moved from its storage – file, object, cloud, or tape – to another location the stubs can break. The HSM then no longer knows where the data has been moved to, and it can become orphaned. The stub has a proprietary format for accessing the moved data, so data cannot be accessed without the stub. When primary storage is tech refreshed, stubs can become broken or corrupted.

StrongLink Autonomous Data Management – The Modern Alternative to HSM

StrongLink connects across bridges multi-vendor storage systems 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 platform according to lifecycle or other policies. In this way the system can use any vendor storage type, including disk, tape, or cloud. StrongLink makes sure data is accessible no matter where it resides, minimizing disruption to users. 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.
