A modified bitmap and a tree of bitmap summary pages are used to manage the free space of a large scale storage system. The bitmap is separated into fixed size pages and has bitmap summary entries to summarize the information in the bitmap. Bitmap summary pages can be further summarized into secondary summary pages. The tree data structure can continue to N levels until a topmost level has one bitmap summary page."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Scalable space management using bitmap summary tree","description":"Systems and methods for allocating space in persistent storage are provided.
