The value of the one or more bits is set to a value configured to prevent a copy-on-write operation being applied to the one or more data tracks to which the read access was detected. Corresponding systems and computer program products are similarly disclosed, all of which advantageously improve storage system performance by reducing I/O bandwidth via preventing unnecessary copy operations."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reducing data storage system I/O bandwidth via read-once point in time copy","description":"A computer-implemented method includes: detecting a read access to one or more data tracks of a target data storage module; and setting a value of one or more bits in response to detecting the read ac","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9601151","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.
