VHD Chain Operations - Merge Consolidate differencing disks
into Another differencing disk New base disk No Maintenance version
can exist No Test version(s) can exist
Slide 24

Slide 28
Exporting vDisk Versions
Slide 29
Copy new versions to new store location Copy XML file to new
store location
Slide 30
Importing vDisks Versions Copy vDisk and any associated
properties files to shared storage Check vDisk versions to be added
to vDisk pool
Slide 31
Import and export of both versioned and unversioned vDisks,
from an existing store to a store in a different farm Import or
Export of VHDs and VHD chains Treat disks from external sources as
single VHD All differencing disks not exported with PVS must be
merged to a base disk before imported VHD Chain Operations
Import/Export
Slide 32
Performance The longer the VHD chain the more IOPS and memory
it will consume Upgrade and backward compatibility Upgrade ALL
SERVERS before using vDisk versioning Old target drivers specific
versions are compatible with vDisk versioning Performance
Considerations

Automated vDisk Updates
Slide 34
Automates updating of vDisks Electronic Software Delivery (ESD)
tools or scripts can be used: SCCM and WSUS in first release Others
including AV tools in subsequent releases Multiple supported

Inventory and Replication
Slide 45
In-memory Inventory Table created at startup Keeps track of
every vDisk version in the file system Keeps track of which disks
are up to date Let admin choose replication method Examples: DFS,
PeerSync, Robocopy or scripts vDisk Inventory Service
Slide 46
vDisk Replication Status
Slide 47
Will keep PVS server out of HA if vDisk version not available
Better logon with no hanging devices Better reconnect with no Blue
Screens A graphical view to check replication status Replication
