Content
This Redbook guides through the concepts and usage of IBM Storage Scale Information Lifecycle Management policies (ILM). It explains the IBM Storage Scale ILM terminology and describes how the IBM Storage Scale policy engine works. This paper further explains the rule language for migration, placement, and list policies. Many practical examples for IBM Storage Scale policies are provided that can be used to efficiently place, migrate, recall, and list files in IBM Spectrum Scale file systems.
