Storage grid is the best solution to manage the interaction between an application and the storage resources through business rules.
The benefits are:
1. Better performance of applications (immediate access to data through websites and storage supports)
2. Business continuity in real time and protection of DATA(protection of data losses and inactivity)
3. Extensibility and scalability (for all applications and locations)
4. No dependence from hardware and software suppliers (it supports all storage producers)
5. total cost of ownership (consolidated Storage infrastructure; optimized performance in relation to costs)
