Offloaded Data Transfers
Traditional transfers have avoidable resource consumption when (simply) moving data around
Consumes CPU cycles and Memory on hostsUtilizes both storage and network bandwidth
Performance always constrained by available network bandwidth
ODX transparently enables through Drag-and-Drop, Copy, Powershell, Robocopy, etc
Supports local volumes, file shares, VHDs, from within VMs
Great for Hyper-V VM/VHD Provisioning, Data Mining, Hyper-V Storage Migration

Background
NTFS supports volumes up to 256TB
Practical volume size is reduced due to potential volume unavailability with long running CHKDSK
Overall CHKDSK execution time has decreased with every Windows release since Windows 2000
Windows 8 and Windows Server 2012
maximizes volume availability
![Page 35: Windows Server 2012: Storage Capabilities for Everyone Bryan Matthew Program Manager Microsoft Corporation WSV327.](https://reader035.fdocuments.in/reader035/viewer/2022062421/56649dc75503460f94abc282/html5/thumbnails/35.jpg)
Maximizing Availability & Improving Scalability in Windows Server 2012

Modern CHKDSK
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
• Volume remains online
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 Correction
• The user or admin can take the volume offline when convenient, and outstanding logged corruptions are rapidly corrected aka. “spot fixed”
• With CSV, I/O is transparently paused for rapid correction, then automatically resumed

Next-Gen Scalability, Availability, and Data Integrity
Integrated Storage Stack with the Resilient File System (ReFS)
![Page 51: Windows Server 2012: Storage Capabilities for Everyone Bryan Matthew Program Manager Microsoft Corporation WSV327.](https://reader035.fdocuments.in/reader035/viewer/2022062421/56649dc75503460f94abc282/html5/thumbnails/51.jpg)
Introduction
Customer NeedsWindows customers want a cost-effective platform that maximizes data availability, scales efficiently to very large data sets across diverse workloads, and guarantees data integrity via resiliency to corruption (regardless of software or hardware failures)
The Resilient File System (ReFS)ReFS is a new file system targeting these customer needs while providing a foundation for significant future innovations. Windows 8 customers can now deploy the most cost-effective platform for available and scalable data access using cost-efficient storage, by utilizing an integrated storage stack comprising ReFS and Storage Spaces.
![Page 52: Windows Server 2012: Storage Capabilities for Everyone Bryan Matthew Program Manager Microsoft Corporation WSV327.](https://reader035.fdocuments.in/reader035/viewer/2022062421/56649dc75503460f94abc282/html5/thumbnails/52.jpg)
ReFS
Integrity of Metadata and (optionally) User DataChecksums detect changes to on-disk representation of dataUtilizes data redundancy offered by Storage Spaces to auto-correct corruptionsMetadata always protected and auto-corrected. Optionally, user data can be protected and similarly auto-correctedScrubber to protect against latent corruptions
