Explanation
Logical groups (C) allow you to organize storage resources by application or business function, making it straightforward to monitor capacity consumed by a specific application across all associated volumes and pools. Device groups (A) are used to group physical storage devices for management purposes, not for application-level capacity tracking. Host groups (B) organize host access to storage ports/LUNs for zoning and connectivity control, not capacity monitoring. Application groups (D) is not a standard Hitachi Device Manager feature - it is a distractor likely designed to tempt those who reason by name alone.
Memory tip: Think "Logical = Let me see by workload" - logical groups mirror how your business thinks about data (by app or service), so they're the natural lens for application-level capacity reporting.
