With the_________feature (for file) of Huawei hybrid flash storage, data in the primary file system...

The required feature is SmartMobility.

The function implements policy-driven movement of file data according to its value or activity level. Frequently accessed, performance-sensitive data remains on the local primary storage, while colder data can be relocated to remote storage resources. The objective is to preserve high performance for active data while reducing the cost of retaining less frequently accessed information.

Huawei characterizes next-generation hybrid flash storage as supporting “Free warm and hot data flow” and states that “Warm and hot data can be migrated in a gateway-free, software-free, and cross-device manner.”

The broader tiering architecture similarly describes policy-based classification of hot, warm, and cold data and automated migration according to storage policies. This enables the physical location of cold data to change without requiring the application to manage the movement manually.

SmartMobility extends that lifecycle principle to file-service scenarios in which cold file data is migrated away from the primary system to suitable remote devices while the frequently accessed portion remains local.
