IBM TotalStorage SAN File System is designed to help you build a tiered disk-storage environment. It is designed to provide policy-based, data movement while avoiding disruption to applications that can help IT managers reduce overall disk-storage costs significantly.
SAN File System is designed to help you match the value of your data to the appropriate cost and performance of your storage. The solution is designed to allocates files to the most appropriate tier of storage automatically, and moves files to other tiers of storage while avoiding disruption to applications throughout the lifecycle of your data. Data that is no longer needed may be deleted, automatically.
With SAN File System, your most recent and critical business data can reside on your highest-performance storage, while older and less-critical business data can reside on lower-cost storage.
Data movement across tiers of storage is designed to occur without impact to end users and business applications, because the files remain in the same place in the directory structure, regardless of the physical tier of storage they reside on. Data residing in multiple tiers of storage is available online to business applications.
