A method includes receiving a user I/O write request comprising data to be written to a RAID array operating in a degraded mode, and determining whether spare capacity has been allocated for rebuilding missing data of an inaccessible storage device of the RAID array and whether a missing data block, which is associated with I/O write request, has been rebuilt to the spare capacity. A degraded write operation is performed without using the spare capacity, when the missing data block, which is associated with the data of the I/O write request, has not been rebuilt to the allocated spare capacity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Balancing resiliency and performance by selective use of degraded writes and spare capacity in storage systems","description":"Techniques are provided for processing user input/output (I/O) write requests in a fault-tolerant data storage system (e.g., a RAID storage system) by selecting between performing a degraded write ope","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11301162","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.
