NetApp AutoSupport technology monitors customer storage environments and provides intelligence to optimize storage. The amount of data received doubles every 16 months, so NetApp IT sought a more flexible archiving solution. They expanded their one-tier system to a three-tier solution with hot, warm, and cold tiers to automatically migrate older data and keep recent data accessible. Data older than 12 months is cold archived for cost savings, 6-12 months is warm for performance and cost, and under 6 months is hot for performance.
