The storage nodes is in a hierarchical tree arrangement, and each storage node in each layer of the tree is allocated with a plurality of identities and configured for remaining hash space with consistency. Instead of sharing one hash space among all storage nodes, there are a plurality of hash spaces kept consistent in each layer of the storage hierarchical tree."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods of handling node failure in a distributed data storage using multi-layer consistent hashing","description":"Disclosed is a systems and methods of distributed data storage using multi-layers consistent hashing comprising: a plurality of storage nodes providing data storage and redundancy protection; a plural","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11461203","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.
