24. Storage Spaces delivers a new category of highly capable storage solutions to all Windows customer segments at dramatically lower price-points and maximized operational simplicity

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

26. ReFS is a new file system delivering on demanding customer needs while providing a foundation for significant future innovations. Windows Server 2012 customers can deploy the most cost-efficient platform for available and scalable data access using commodity storage, by utilizing an integrated storage stack comprising ReFS and Storage Spaces.

27. ReFS Overview
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 of the file system remain unaffected and online.
Availability
Architecture enables efficient evolution for new storage devices and new access patterns
Architectural Evolution

28. Integrity
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

29. ReFS and Storage Spaces
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

On media failure, the scrubber will get an alternate copy of the data
With NTFS, Scrubber verifies all copies can be read

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

31. Scalability
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

32. Availability
ReFS provides rapid recovery from file system corruption without affecting volume availability
If corruption occurs:
If a redundant copy is available, then correction happens automatically
If a redundant copy is unavailable, then repair happens online and only the corrupt portion of the namespace is affected

33. Application Compatibility (1/2)
While delivering on new capabilities, ReFS also builds on NTFS’ 20 years of application compatibility
ReFS largely reuses the upper-layer to provide API compatibility to applications while providing a new on-media engine that enables new capabilities
NTFS.SYS
Upper API Layer
On-media Store
ReFS.SYS
Upper API Layer
MinStore

34. Application Compatibility (2/2)
ReFS supports the majority of the Win32 APIs
However, there are certain features that ReFS does not support
Legacy
Short Names
TxF
NTFS-specific
Reparse Index
Named Streams
MFT
Superseded
NTFS Encryption
NTFS Quotas
NTFS Compression
Other
Hard Links          
Extended Attributes

Windows Server 2012 customers can deploy the most cost-efficient platform for available and scalable data access using commodity storage, by utilizing an integrated storage stack comprising ReFS and Storage Spaces.

37. Maximized Data Availability
Modern NTFS CHKDSK

38. Confidently deploy multi-TB volumes with Windows Server 2012

39. Maximizing Availability in Windows Server 2012
Improved detection and handling of corruptions in NTFS
Change in the CHKDSK execution model
Separate analysis and repair phases
Integration with Cluster Shared Volumes (CSV)
In Windows Server 2012, NTFS reaches new levels of availability through significant CHKDSK enhancements

40. Online Analysis and Repair Workflow
Possible Corruption Detected
NTFS detects a perceived anomaly in file system metadata
Online Self-Healing
NTFS attempts to rapidly self-heal
Volume remains online
Online Verification
NTFS will validate whether issue is transient or genuine
Online Identification & Logging
If not self-healed, NTFS will identify and log corrective actions for later processing
User or Admin is notified
Volume remains online
Precise & Rapid Offline Repair
The user or admin can take the volume offline when convenient, and outstanding logged corruptions are rapidly repaired a.k.a. “spot fixed”
With CSV, IO is transparently paused for rapid repair, then automatically resumed

41. Only Seconds Offline to Repair a Corruption

42. Confidently deploy multi-TB volumes with Windows Server 2012

43. Storage Management PowerShell with SMI-S Integration
Ease of Storage Administration
Storage Management PowerShell with SMI-S Integration

44. With Windows Server 2012, storage management is an integrated and intuitive experience, which reduces operational complexity

45. A New Approach to Storage Management

Designed for remote administration and scripting
WMI-based class structure for managing heterogeneous storage
SMI-S integration enables broad multi-vendor interoperability
Storage Management Provider (SMP) framework enables easy extensibility
