Fully Automated Storage Tiering (FAST)

EMC fully automated storage tiering (FAST) automatically moves active data to high-performance storage tiers and inactive data to low-cost, high-capacity storage tiers. The result is higher performance, lower costs, and a denser footprint than conventional systems. With FAST, enterprise flash drives increase application performance by up to 800 percent, and serial advanced technology attachment (SATA) disk drives lower costs by up to 80 percent.

Who uses FAST, and why

FAST optimizes performance, cost, and floor space, allowing IT organizations to manage more information more efficiently in a smaller footprint while lowering power and cooling, capital, and operational costs. Any organization can use FAST with systems that store and process active and inactive data that’s difficult to identify and move manually to different tiers.

How FAST works

FAST continuously monitors and identifies the activity level of data and automatically moves active data and inactive data to the most appropriate storage tier based on policy. Active data goes to the highest performance tier, and inactive data to the lowest-cost, highest-capacity tier. Policy settings enable administrators to control and manage automated activity.

Benefits of FAST

FAST makes a storage system both faster and lower-cost because it only uses high-performance tiers when needed and low-cost, high-capacity tiers when possible. Policies provide control for how performance and cost are optimized, and the automation of FAST means that the storage system has no added management burden compared to slower, more costly systems.
