SGI® DMF™ — Storage Tier Virtualization
Proven for over 21 years in some of the world's most demanding data environments.
SGI DMF is a powerful storage tier virtualization solution for creating and managing a virtualized storage fabric, which can include disk, tape, object and cloud storage in a massively scalable, completely protected environment at a fraction of the cost of conventional solutions.
Relied upon by some of the world's largest online data repositories for over 20 years, DMF enables all data to appear simply as online data, regardless of which tier or storage device is may be on at the moment. This is made possible with a rich policy engine that gives IT administrators the ability to optimize placement of data on any or all storage devices and locations based upon what works best for the access requirements and data protection policies.
Based on user criteria DMF continuously monitors and automatically migrates data between storage tiers with different cost and performance characteristics. Only the most critical or timely data resides on higher performance, more expensive storage media, while less critical or timely data is automatically migrated to less expensive, lower performance storage media. Data always appears to be online to end users and applications regardless of its actual storage location.
DMF has been protecting data in some of the industries largest virtualized environments all over the world, enabling them to maintain uninterrupted online access to data for more than 20 years. Some customers have installations with over 100PB online data capacity, and nearly 2 billion files, at a fraction of the cost if conventional online architectures.
DMF's industry leading features include a rich policy engine that gives IT administrators the ability to have complete control over how data is managed and protected. DMF operates in the background so there is no interruption or degradation of service to end users and applications, even as administrators upgrade or replace storage infrastructure over time. Because data protection is inherent in the DMF virtualized storage fabric, it also enables IT administrators to reduce the back-up windows in their primary storage tiers.
DMF's Active Backup feature allows multiple copies of data to be created during the migration process. Because copies of critical data already exist, DMF can significantly reduce the time it takes to perform storage backup since only file system and DMF database information need to be copied during the backup process.
DMF delivers significant storage management benefits including:
