Slide 10

New VHD types New vDisk lifecycle operations and modes New target device types How does Versioning Work?

Slide 11

The existing VHD file types are preserved Fixed Dynamic New VHD types VHD Base Disk, *.vhd (either fixed or dynamic VHD) VHD Differencing disk, *.avhd New VHD Types

Slide 12

VHD Chains Examples

Slide 13

VHD Chains Read/Write Access

Slide 14

VHD Chains Multiple Streams

Slide 15

Properties file for each version to retain printer configurations Cache type will be determined by top version Lock file will exist for each version Properties & Lock Files

Lifecycle Operations Promoting a vDisk Version Promoting a Maintenance to Test or Production

Slide 22

Lifecycle Operations Reverting a vDisk Version Reverts a Production to Maintenance or Test Reverts a Test into Maintenance

Slide 23

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 27

Automatic Merge Warning

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

Slide 33

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 hypervisors XenServer, Hyper-V, ESX Multiple update modes Scheduled Manual Automated vDisk Updates

Slide 35

vDisk Update Management Components

Slide 36

Remote vDisk Store Virtual Host ProviderOptional: ESD Server Provisioning Services Provisioning Services designated for Automated vDisk Updates

Slide 37

Configuring Image Updates (1) Enable vDisk Update in the site properties dialog

Slide 38

Configuring Image Updates (2) Add a Host

Slide 39

Configuring Image Updates (3) Select vDisks and assign them to VMs

Slide 40

Configuring Image Updates (4) Create an update task

Slide 41

Citrix vDisk Update Service

Slide 42

Add Scripting Points into Update Sequence Server Pre- update script Prepare Image Post- update script Start VM Maintenance Device Pre- update script Apply updates Post- update script Shutdown Server Post-VM script Submit Image Post- update script Update Complete

Slide 43

Server side Create scripts folder under installation folder Client side names to be exact Create scripts folder under installation folder Preupdate.bat Postupdate.bat Enabling Scripting

Slide 44

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 Benefits Summary
