Resilient File System (ReFS) Next-generation scale, availability, and integrity

All metadata corruption is always detected. Optionally, user data corruption is also detected. ReFS utilizes Storage Spaces’ resiliency to auto-correct. Integrity ReFS efficiently scales to PB datasets comprising very large files. Scalability

ReFS maximizes data availability. If corruption occurs and a redundant copy is unavailable, the non-corrupt portions remain unaffected and online. Availability Architecture enables efficient evolution for new storage devices and new access patterns. Architectural Evolution

Allocate-on-write eliminates corruption from errors associated with in-place update Checksums detect whether the data on media has changed since it was last written File system metadata is always protected, maximizing online operation Flexible user data protection is configurable on a per-volume, per-directory, and per-file basis

Data Volume - NTFS Scrubber Data Volume - ReFS Storage Pool Data Copy0 Data Copy1 Data Copy2 On media failure, NTFS will get an alternate copy of the data With NTFS, Scrubber verifies all copies can be read Checksum is inspected on all copies of the data If corruption detected, trigger auto-correct and return a healthy copy of the data With ReFS, Scrubber verifies checksums on all copies and auto-corrects as needed Copy1 Data Copy2 Data Copy0 Data Mirror Space

Application accesses data ReFS volume detects corruption and automatically replaces the corrupt data with correct data Mirror space offers all data copies to the file system ReFS

ReFS uses a highly scalable, flexible, B+ tree data structure for all metadata Ensures maximum scalability and volume sizes beyond NTFS File system abstractions are implemented using key-value tables built from the B+ trees Capacity allocation is handled by a hierarchy of allocators Ability to allocate at different sized granularities
