The storage control apparatus manages mapping information that expresses a correspondence relationship between a virtual area and a physical area. The storage control apparatus performs at least one of change of any of fine-grained virtual areas to a coarse-grained virtual area and change of any of coarse-grained virtual areas to a fine-grained virtual area, based on the number of duplication areas of each virtual area and a size of the mapping information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Storage system","description":"A storage control apparatus performs, for each virtual area to which a physical area is allocated, any one of coarse-grained management for managing a correspondence relationship between a virtual are","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9720608","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
