The system migrates frequently accessed data (hotspot data) to high-speed disks, accelerating the system response to hotspot data. The storage performance of the overall system is enhanced. -Reduced overall cost of deployment: Cold data is stored on large-capacity and low-rotational speed disks, maximizing the cost effectiveness of different storage media and reducing deployment and maintenance costs. -Intelligent data management: Based on custom file storage policies, InfoTier automatically collects properties, such as the file size, access time, and access frequency. Data is automatically migrated based on the mapping between file properties and storage tiers, simplifying management and reducing management cost accordingly.
