Some percentage of your data is inactive--it hasn't been accessed in weeks, if not months. IBM Tivoli Storage Manager for Space Management (formerly known as HSM) can automatically move inactive data to less-expensive offline storage or near-line storage, freeing online disk space for more important active data.

IBM Tivoli Storage Manager for Space Management frees administrators and users from manual file system pruning tasks, and defers the need to purchase additional disk storage, by automatically and transparently migrating rarely accessed files to Storage Manager storage, while the files most frequently used remain in the local file system. IBM Tivoli software now offers increased scalability and performance via parallel migrations, improved candidate search and optimized synchronization between the Storage Manager server and the hierarchical storage management (HSM) client.

IBM Tivoli Storage Manager for Space Management complements both IBM Tivoli Storage Manager and IBM Tivoli Storage Manager Extended Edition. OTG's DiskXtender 2000 (DX2000) provides migration of NTFS files to the IBM Tivoli Storage Manager server. This gives DX2000 users the ability to have their data managed and protected by the centralized Storage Manager server, and it gives Storage Manager users the ability to manage data space on the Windows® platforms.
