Which lifecycle management concept does StorageGRID use to distribute copies of object data?

• A. Storage lifecycle management (SLM)
• B. Information lifecycle management (ILM)
• C. Application lifecycle management (ALM)
• D. Object lifecycle management (OLM)

Answer: (B)

The concept being tested is Information Lifecycle Management. StorageGRID uses ILM to control how object data is placed, protected, and retained over time. ILM policies define what happens to each object as it ages: how many copies to keep, where those copies live (across different sites or storage tiers), how long to retain them, and when to move or delete them. This policy-based approach lets StorageGRID distribute replicas or use erasure-coded data across multiple locations to ensure durability and availability, while also allowing data to transition to cheaper storage as it becomes less frequently accessed. The other terms describe different areas (software development, generic storage asset management, or a non-standard object-specific term) and don’t capture the way StorageGRID implements data distribution and lifecycle management across the grid.
