2. Session Overview System Center Virtual Machine Manager 2012
Windows Server 2012
Offloaded Data Transfer (ODX)
Support for Thin storage (TRIM/UNMAP)
Windows Hyper-V (VHDX & Virtual HBA)
System Center Virtual Machine Manager 2012
Storage Management Services (SMI-S)
Storage Integration
Extreme Virtual Machine Performance

3. Efficient Storage - ODX

4. Offloaded Data Transfer (ODX)
Why?
We transfer a great deal of data
Microsoft SQL Server environments
Backups to alternate systems
Virtualised environments
Movement of VHDs & Virtual Machines
Deployments from Templates
Data movement consumes resources
Read block from storage
Transfer block to alternate system
Write block to storage

5. Offloaded Data Transfer (ODX)
TechEd 2013
4/19/2017 8:39 AM
Offloaded Data Transfer (ODX)
How?
Built into Windows 2012
SCSI Inquiry on LUN
Firmware prior to Q4/2012 might not have support.
Automatically invoked
Any operation invoking Windows Copy API
Within a LUN
Within a host across LUNs
Across Windows 2012 Servers (via SMB 3.0)
Third party “Copy Engine”
Target ODX capable?
Yes
Pass token
Offload Read
Write using Token
Transfer executed in “chunks”

6. ODX Demo

7. VIDEO DELETED FOR WEB OPTIMISATION

8. ODX – Operational Behaviour
ODX can dynamically fallback to legacy read/write
When a fallback occurs
ODX session switches to legacy copy and remains in legacy copy
Timer (3 minutes) begins between source/target pair for copy engine
Already in-process ODX operations on separate copy engine continue
NOTE: Install KB “Offloaded Data Transfers fail on a computer that is running Windows 8 or Windows Server 2012”
Associated with KB

9. ODX Control Storage arrays may provide control Volumes can “opt-out”
This can occur with certain filter drivers
Disable ODX
Set-ItemProperty hklm:\system\currentcontrolset\control\filesystem -Name "FilterSupportedFeaturesMode" -Value 1
Enable ODX
Set-ItemProperty hklm:\system\currentcontrolset\control\filesystem -Name "FilterSupportedFeaturesMode" -Value 0

10. ODX – Additional Uses VHDX creation Hyper-V Storage Migration
Special case of “Write Using Zero Token”
“Writes” zeros to allocated storage range
Hyper-V Storage Migration
Transfer of block storage occurs via array

11. ODX and SCVMM Demo

13. Thin Storage - UNMAP

14. Thin Device Support Why? Making storage more efficient
A lot of “empty” storage (volumes and within files)
Windows Server NTFS implemented logical file removal
Making storage more efficient
Space is returned to Thin Pools
Previous storage allocations are “zeroed”

15. Thin Storage Volumes How? Built into Windows 2012
TechEd 2013

Thin Storage Volumes
How?
Built into Windows 2012
SCSI Inquiry on LUN
Firmware prior to Q4/2012 might not have support.
Automatically invoked
File deletion can generate UNMAP operations
Background operations
As a scheduled task through “Optimize Drive”
Volume initialization (format) can generate UNMAP
File Delete
Thin storage?
UNMAP

16. UNMAP Demo

17. VIDEO DELETED FOR WEB OPTIMISATION

18. UNMAP – Operational Behaviour
Hyper-V VHDX supports Thin/UNMAP
Windows Server can serialise operations
File is deleted : NTFS volume update may wait
NTFS volume create can traverse all blocks looking to deallocate
These items may cause operations to appear to “stall”
NOTE: Watch for HotFix
Resolves serialisation of UNMAP in NTFS volumes

19. UNMAP Control Storage arrays may provide control Disable UNMAP
fsutil behavior set DisableDeleteNotify 1
Enable UNMAP
fsutil behavior set DisableDeleteNotify 0

20. Hyper-V support: ODX & UNMAP
Windows Server 2012 as parent OS & VM OS
Support for ODX “pass-through” with VHDX
Support for UNMAP “pass-through” with VHDX
Virtual Machine with Virtual HBAs
This is effectively the same as a physical server for ODX/UNMAP

21. Trivia Time!

22. Windows Storage Management

23. Windows Server Storage Management
Standards based Storage Management Support for SMI-S providers

24. Storage Management with SMI-S Demo

26. Scripts are great and all …. But ….
