Migrating Data of Sequential Workloads to Zoned Storage Devices
Techniques are provided for migrating data of sequential workloads to zoned storage devices. One method comprises obtaining a sequentiality classification of at least one workload of an application associated with a storage system comprising a plurality of zoned storage devices; and migrating data from one or more non-zoned storage devices that store data of the at least one workload to one or more zoned storage devices in response to the at least one workload being classified as a sequential workload. A sequentiality classification of a workload (e.g., as a sequential workload or a random workload) can be determined by: (i) evaluating the application name and/or application type of an application, (ii) learning input-output workload patterns, such as sequential read/write operations or random read/write operations, and/or (iii) detecting the application access mode to persistent volumes, such as a sequential write access mode.
