ReFS: Performance

ReFS (Resilient File System – is a Microsoft file system, which ensures data integrity by means of resiliency to corruption (irrespective of software or hardware failures), increases data availability and scales to large data sets across various workloads. Its data protection feature is represented by the FileIntegrity option, which is responsible for file scanning and repair processes.

ReFS: Log-Structured

Here is a part of a series about Microsoft Resilient File System, first introduced in Windows Server 2012. It shows an experiment, conducted by StarWind engineers, dedicated to seeing the ReFS in action. This part is mostly about the FileIntegrity feature in the file system, its theoretical application and practical performance under real virtualization workload. The feature is responsible for data protection in ReFS, basically the reason for “resilient” in its name. It’s goal is avoidance of the common errors that typically lead to data loss. Theoretically, ReFS can detect and correct any data corruption without disturbing the user or disrupting production process.

ReFS: Overview

This is a short overview of Microsoft Resilient File System, or ReFS. It introduces the subject and gives a short insight into its main characteristics and theoretical use. It is a part of a series of posts dedicated to ReFS and is, basically, an introduction to the practical posts. All the experiments that show how ReFS really performs, are also listed in the blog. ReFS seems to be a great replacement for the NTFS and its resilience is most convenient for cases, when data loss is critically unacceptable. The file system cooperates with Microsoft Storage Spaces Direct in order to perform automatic corruption repairs, without any attention of the user.
