InfoTier, which is also named dynamic storage tiering (DST), can store files on storage devices with different performance levels according to the file properties, and can migrate files between devices. In this way, InfoTier fits users' requirements on the files processing speed and storage capacity, and ensures optimized space utilization, enhanced access performance, and reduced total deployment cost.

Application restrictions of OceanStor 9000 InfoTier include: - A node cannot be directly migrated from one node pool to another. If you want to change the node pool of a node, delete the node from its original node pool, and then add the node to another node pool by expansion. - A node pool belongs to one storage tier. The system creates a default storage tier for a new node pool, and you can use DeviceManager to affiliate this pool to another storage tier. - You cannot delete a node pool containing nodes or a storage tier containing node pools. If you want to delete the node pool or storage tier, you must empty it first. - Popularity statistics are performed based on files. - During restriping or file MIGRATE, ensure that data reliability is not impaired and the redundancy ratio remains unchanged.

OceanStor 9000 InfoTier mainly applies to scenarios that require automatic data categorizing and intelligent data management. In scenarios that require automatic data categorizing and intelligent data management, OceanStor 9000 allows data to be automatically stored in different storage media and adjusts data storage locations according to file attributes, improving overall system storage performance and cutting costs.
