Error-correcting codes are used to identify different front-end tracks in a back-end track when the back-end track is copied from the managed drives into storage array memory. CKD front-end tracks can be split into multiple partial CKD front-end tracks that are located at contiguous address space in different back-end tracks. The front-end tracks that are located in a particular back-end track may be selected to reduce or minimize unused space. The front-end tracks in a back-end track may be logically stored on different production volumes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-BCRC raid protection for CKD","description":"A storage array that presents a logical storage device to hosts that is accessed using front-end tracks and access tangible managed drive using back-end tracks locates multiple front-end tracks in ind","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11256447","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.
