Microsoft Details Its New File System ReFs Coming In Windows 8

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
