25 The Great VDI Divide - IT Cost or User Personalization? Common Base Image Operating System or User Profile & Settings Departmental Applications User Installed Applications Local Peripherals User Profile & Settings Departmental Applications User Installed Applications Local Peripherals User Profile & Settings Departmental Applications User Installed Applications Local Peripherals BASE / PARENT VM Base Image Base Image Base Image Operating System Operating System Operating System VM1 VM2 VM3

26 Citrix Personal vdisk Satisfies Both! User Profile & Settings Departmental Applications User Installed Applications Local Peripherals User Profile & Settings Departmental Applications User Installed Applications Local Peripherals User Profile & Settings Departmental Applications User Installed Applications Local Peripherals PVD 1 PVD 2 PVD 3 Common Base Image Enterprise scope Highly personalized for users Increased user acceptance Reduced infrastructure reqs. Centralized management Uptime & predictability Operating System BASE PARENT VM 26

27 Complete personalization Personalized PC experience Departmental & user installed apps Personalized apps, data & prefs Efficiency and management Single OS image management Reduce storage by 65% Enables pooled VDI for all

28 Delivering and Managing the PvD Desktop 1. Common Base Setup» Install OS, common apps and VDA in base VM» Create VM pool and entitle 2. User Access» Login through Receiver User s Workspace» PVD assigned on first login» Locally administered dept. apps» User installed apps» Streamed apps 3. Image Update Common Base Image Operating System» Update base VM without affecting any user personalization

29 What Does Personal vdisk Do? PVD intercepts application I/O requests (files, registry keys, registry values) and redirects these requests. Requests are satisfied from the base Virtual Machine or Personal vdisk. C PVD decides which layer to satisfy the request from by consulting i t r a set of rules found in a resource i catalog. C Personal vdisk provides a blended view of both base Virtual o n f Machine and the users Personal ivdisk. x d e n t i a l -

30 Inventory The PVD inventory consists of a few things The resource catalog A set of 0-byte sentry files which track files sourced from the base VM Essentially information about what is installed in the base VM t The inventory is created by the administrator r Start -> Citrix -> Personal vdisk -> Update Inventory x C At each base VM shutdown via the shutdown o tracker n These options are only available in the base f VM C i i i d e n t i a l 30

31 Template VHD The basis of personalization Inventory is computed and placed in a template VHD which is stored on the base Virtual Machine. Template VHD is saved and used during first time pool VM use. t The XenDesktop catalog is created r after inventory creation. This creates the PVDISK for the user. C i i x C o n f i d e n t i a l -

32 The personalization disk Personal vdisk disks can be attached to any Storage Repository supported by the hypervisor. Can be located on different SR allowing IOPS to be spread across spindles. PvD size and location selected in Desktop Studio / PVS XenDesktop Setup Wizard during catalog creation. PvD disks can be resized after initial creation.

33 Pooled VM User Changes Over time users will make changes to their environment Add/delete/change files Add/delete/change registry keys/values Install/uninstall software (if rights permit) C Receive provisioned applications (eg, via SCCM) i It s important to note that PVD captures x all changes being made C These changes are redirected to the PVD VHD o file n No changes to the VM image are permitted f t r i i d e n t i a l 33

34 Base VM Life Cycle Base VM images can and will change over time A new inventory will be computed and stored in the base VM On next pooled VM boot the VM will notice that it is out-of-date C with respect to the new base VM i r PVD drivers will not start virtualization in this i case x PVD drivers will mount the VHD and merge the changes from the previous inventory C with the new inventory, respecting any changes o made by the user. n After this 3-way merge the VM will restart. f e Note the broker will stop user logins n during image update t i d t i a l 34

40 Deployment Considerations

41 Choosing a solution Choose MCS if you Are deploying VDI only Are using NFS storage Need to be quickly up and running Have a lot of dedicated desktops Are managing individual single sites Add PVD for Personalisation Choose PVS if you Are deploying multiple FlexCast models Are using CIFS, SAN, or NFS storage Need maximum performance and scale Need image management features Are managing across multiple sites Add PVD for Personalisation 2012 Citrix Systems, Inc. All rights reserved

42 Storage considerations MCS PVS Single storage tier ᵒ Same storage for base and diff disks ᵒ Configure for IO optimization More IO intensive ᵒ Dynamic diff disks ᵒ IntelliCache on XenServer an option Storage capability dependent ᵒ NFS storage preferred ᵒ Block only option for Hyper-V Two storage tiers ᵒ Base disks on any storage ᵒ Write caches on IO optimized storage Less IO Intensive ᵒ Fixed size write cache disks ᵒ Caching in RAM on PVS servers Storage capability agnostic ᵒ SAN, SMB 2.1+, NFS 3+, HDD ᵒ No dependence on cloning capabilities 2012 Citrix Systems, Inc.

47 Checklist for a successful deployment Run a real Proof of Concept Try out your production storage and network environment Start with clean images A fresh or tightly controlled build will keep junk from causing problems Rationalize your images Do you really need all those variants?
