Azure NetApp Files introduces an enhancement to storage with cool access for Premium and Ultra service levels that more precisely aligns throughput with data tiering. When cool access is enabled, maximum throughput is dynamically calculated based on the amount of data tiered to cool access storage, rather than applying a fixed reduction. Hot data retains its configured performance, and throughput is adjusted only when data is tiered to the cool tier. This enhancement delivers more predictable QoS behavior while optimizing performance and cost as data access patterns evolve, without requiring manual tuning or reconfiguration.
