Module 4: Desktop Management

1. Module 4: Desktop Management

2. Agenda • Desktop deployment • Options and process • Persistent vs Non-Persistent Desktops • Template Usage • Desktop Configuration Options • Maintenance Windows • Searching and filtering

3. Understanding Desktop Deployment

4. Desktop Deployment • VM is created • Personalization layer created • ‘Boot’ Image created (BIC) • VM reconfigured • VM Powered on • Windows Mini-Setup executes • Registration with broker (more in Module 5) • Non-persistent reboot

5. VM Created • VM hardware settings • Memory, CPU, network, OS Type, etc • VM Name in vCenter • The VM is just a shell at this point. Once the VM itself is created Unidesk begins the process of making is an operational VM

6. Boot Image Creation (BIC) • “Boot” image VMDK is wiped • Files needed prior to CFS/NTFS start are copied from layers to “boot” image • Registry is composited (Blended) and put on “boot” image • Boot image is connected to VM as first Disk Personalization Layer App layer App layer App layer App layer O/S layer

7. BIC of a NEW Desktops Connect MM “boot” disk to CP for updates – You will see reconfigure tasks in vCenter Repartition and Format (Zero to Boot Image out) OS Layer Bootfiles and Registry and copied (based on bootfiles needed before CFS loads) Iterate through each layer copying bootfiles (App Layers and Pers Layer) Iterate through each layer reading the registry changes in to the boot image Reconnects the boot image to the VM and readies for Power On

8. Power On and Mini-Setup • At this point the Pers Layer is a PERSISTENT disk • VM is powered on • Desktop begins mini-setup reading Unattend.xml • Depending on unattend.xml configuration and desktop type VM may reboot once or twice. • This runs ONCE only for any machine!

9. Broker Registration • Each broker’s registration process is slightly different. But keys are as follows: • Happens after mini-setup runs • Must have DNS working and firewall ports open • Non-pers desktops will have registration come BEFORE the Disk is “flipped” to non-persistent • More on brokers in Module 5

10. Persistent/Non-Persistent • Simple difference is that the Personalization Layer is changed to an independent non-persistent disk • Unidesk looks for logout of user and powers off the VM • Broker has power options turned on and powers the machine back on • This hard restart “flushes” the non-persistent disk

11. Persvs Non-Pers Desktop

12. Desktop Configuration Options • Non-Unidesk settings: • Broker/ Pool configuration • Desktop Name • Network • OS Type (for VMware) • Number of CPUs • Memory (VM RAM) • Pagefile size (Windows) • Core Dump Type (Windows)

13. Desktop Configuration Options • Unidesk Specific Settings: • Template • CachePoint or Cluster assignment • Persistent or Non-Persistent • OS Layer and App Layers • Pers Layer size (thin provisioned) and backup settings • Desktop Maintenance Schedule

14. LAB Desktop Creation

15. Unidesk Templates

16. Unidesk Templates • Templates are basically a bill of materials for the desktop • Contains both Unidesk and non-Unidesk info • Not all options have to be configured • Templates can be tied to a pool, but don’t have to be

17. Template Uses • Used to build new desktops • Used in Searching and Filtering to update desktops (based on a specific template or template association w/ a pool) • In later versions will be used to configure Power Management and Power State options

18. LAB Creating and Using a Template

19. Maintenance Windows

20. Maintenance Windows • Created in the Settings and Configuration tab within System Settings • Dictates desktop update behavior based on: • Day of the week • Time of the day • Status of desktop (in use or not) • There are 3 default Maint. Windows defined • 24x7 – wait for user to logoff • System Default Maint. Schedule(9pm-5am & Weekends) • Weekends

21. In Use/Status Option • When a user has logged out… • Means they have logged out NOT just disconnected • Must be logged out for 10 minutes minimum • As soon as possible • Means even if the user is logged in they get logged out for this update.

22. Maint. Window Options - Desktop Editing • Use existing maint. Schedule set for desktop • Execute right now! • Specify a time and date regardless of status • At next user log out

23. LAB Creating and using maintenance schedules

24. Searching and Filtering for desktop updates

25. Search Wizard…

26. Search Wizard • Contains these words = computer names or owners • Have owners in this group = AD or Unidesk Groups • CachePoint = Currently associated w/ a specific CP • Maintenance Schedule = Self Explanatory • Are Using this: • Template = Using that specific template or version • Layer = Using that specific layer or version • Has pending configuration changes

27. Beware • Beware of the non-wild card, wild card… • Search terms do not use wild cards. A Search for Zoo will return both Zoo and Zoom • Search on longer names when possible not just fragments: • MS Office instead of Off

28. LAB Filtering and desktop Updates

29. Questions you may see again

30. When updating a desktop what are the options available for the maintenance window? • You are asked to deploy 50 identical desktops over the next month, what is the easiest way to do this? • Can you have a template with no broker configuration defined? • You notice your non-persistent desktops reboot after they are built. Is this normal? If so Why?
