The capacity usage ratio of the source SSD is a ratio of a used capacity of the source SSD to an available capacity of the source SSD. The storage controller selects at least one destination SSD in the disk group with a capacity usage ratio less than the average capacity usage ratio of the disk group. And then the storage controller calculates an amount of data to be migrated from the source SSD, based on the capacity usage ratio of the source SSD and the average capacity usage ratio. At last, the storage controller migrates the data to be migrated from the source SSD to the one or more destination SSDs."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data migration method, data migration apparatus, and storage device","description":"A method for extending life of a storage system, wherein a storage controller determines a source solid-state disk (SSD) in a disk group with a capacity usage ratio greater than an average capacity us","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9733844","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.
