What is auto tiering?
Auto-tiering is a storage method in which different types of data are directed to separate storage components in a connected or networked storage system.
Auto-Tiering wird auch als automatisierter Tiered storage, automatisiertes Storage Tiering und automatisches Storage Tiering bezeichnet.
In complex systems it may be necessary to distinguish or select different types of data for storage optimization. In such situations, auto-tiering can be an effective way to create storage categories for data.
Auto-tiering solutions can be applied to a logical unit number (LUN) or other types of file systems. IT pros sometimes refer to 'sub-LUN' as a specific type of auto-tiering.
As a specific type of software-defined storage, automatic tiering is often appropriate for systems that contain solid-state drives and other types of storage networks with different types of storage. In many cases, automatic tiering ensures that 'hot' or frequently used data is kept in certain more accessible drives or drives with certain characteristics, while 'cold' data is kept in other types of drives for longer-term storage.
