Microsoft today detailed its new file system for Windows 8 Server that will also be compatible with Windows 8 clients. ReFS, (which stands for Resilient File System), is built on the foundations of NTFS, will have compatibility with older file systems and also provides way for a new generation of storage technologies and scenarios. ReFs features the following,
- Metadata integrity with checksums
- Integrity streams providing optional user data integrity
- Allocate on write transactional model for robust disk updates (also known as copy on write)
- Large volume, file and directory sizes
- Storage pooling and virtualization makes file system creation and management easy
- Data striping for performance (bandwidth can be managed) and redundancy for fault tolerance
- Disk scrubbing for protection against latent disk errors
- Resiliency to corruptions with “salvage” for maximum volume availability in all cases
- Shared storage pools across machines for additional failure tolerance and load balancing
