What technology allows for automated tiering of data based on access frequencies?

The correct choice is FabricPool, which is a technology developed by NetApp that enables automated tiering of data based on access frequencies. FabricPool works by intelligently migrating less frequently accessed data to lower-cost cloud storage, while keeping the more frequently accessed data on higher-performance on-premises storage. This dynamic tiering optimizes storage costs and performance, ensuring that organizations can manage their data in a more efficient manner, taking advantage of the cost benefits of cloud storage alongside the speed of on-premises solutions.

FlexGroup is a technology that allows for the creation of large volumes from multiple storage nodes, enhancing scalability and performance, but it does not specifically handle automatic tiering based on access frequency. RAID, which stands for Redundant Array of Independent Disks, is focused on data redundancy and performance rather than tiering based on access patterns. Data Deduplication is a technique used to eliminate duplicate copies of data but does not involve the tiering of data based on how often it is accessed.

FabricPool ultimately provides an effective means for organizations to manage their data lifecycle more intelligently through access frequency-based data tiering, leading to potential cost savings and optimized performance.
