Trends Driving High Performance Mass
Storage System Requirements
Rapid improvements in applications and algorithms, processing, memory sizes, data collection devices, multimedia capabilities, integration of enterprise data producing multigigabyte-to-terabyte datasets and the need for scalability to petabyte stores.
Significantly slower improvement in storage device performance relative to other system components (e.g., ~ 20%/yr for disk vs. > 50%/yr for processing) yielding increasing I/O imbalance.
The users need for high-level application centered views of information not a low-level storage view.
The shift from centralized to distributed computing and the need to integrate distributed information repositories.
Rapid improvements in local and wide area networking technology.
