Demystifying VMware Mirage: Tips and Tricks for Success Simon Long, VMware Justin Venezia, VMware EUC4815 #EUC4815

2 Agenda  Horizon Mirage – A Quick Overview  Tips & Tricks For Success  High-Level Architecture Examples  Q & A

3 Horizon Mirage – A Quick Overview

6 Typical Use Cases  Automated Windows OS Migration & Deployment  System Recovery (BC/DR)  Hardware Migration & Refresh  Simplified Image Management  BYOD (With Fusion Pro & VMware Workstation)

7 Mirage server • Images are stored and manipulated in datacenter • Unlike VDI, images do not run in datacenter • Images are automatically synchronized with endpoints • Logical layering of images increases granularity Centralized images Data Transfer optimized • Stores data only once • Transfers only what is not present on destination • All transfers are compressed Base layer Desktops or laptops with Mirage client • Endpoints always run local copy of Windows • Does not require hypervisor or format • Local drivers are leveraged • Changes from Mirage are merged directly into Windows End users Mirage Architecture – Manage Centrally, Execute Locally!

8 Layered, Single Image Management Horizon Mirage Layers  Layers are stored in the data center  Mirage performs granular operations on Mirage-managed endpoints  Orange layers continuously backed up from endpoints  Green layers managed by IT End User PC Machine Identity Layer (identity, customizations) User Personalization Layer (user data, installed apps & profile) Base Layer (OS, infra SW, core apps) Driver Library Mirage Application layers

9 Bringing it all Together: Single Image Management Single Base Layer Windows 7 Antivirus Common Apps Dell Drivers HP Drivers VMware Drivers Finance Apps HR Apps IT Apps Up to 20,000 Endpoints

10 Horizon Mirage Components Horizon Mirage Client  Four Megabyte MSI deployed to all clients  Mirage-related endpoint operations & File/Folder Recovery Horizon Mirage Servers  Mirage Management Server (interfaces with DB)  Mirage Server (controls all operations and objects) File Portal And Web Management  Optional feature(s) used for Web Administration & File/Folder Recovery  Must be on a server that is on the domain  Can co-reside on the Mirage Server itself Branch Reflector  “In-branch” device that can service base layers & updates, drivers, and migration functionality, eliminating WAN traffic for certain Mirage operations  No additional setup/install required; simply designate an existing endpoint as a Branch Reflector Management Console  MMC Admin Console to connect to Mirage Management server

12 Tips and Tricks For Success

13 Endpoint Assessment  Know Thy Endpoint! • If you don’t understand what’s on the desktop, you won’t know what or how much data you will be managing  Good data drives good Mirage design decisions  Tools & Techniques • Lakeside/Liquidware Labs • SCCM or other Desktop Inventory Tools • Mirage PoC (Sample of Desktops)  Hardware, Networking & Security • Speed of Hardware • Connectivity (LAN/WAN/VPN) • Disk Encryption & Endpoint Protection

14 Endpoint Assessment (cont.)  Application Rationalization • Installed Applications • Are those apps READY for Windows 7?  User Data & Behavior • Personal vs. Corporate Data • Movies, Pictures, Music • The “Gypsy User”

15 Application Integration  Mirage does not differentiate how applications are installed • It’s WHERE they are installed that’s important  Place applications in the Base Layers when it makes sense • Globally-used applications • System-level software (AV, VPN, etc.)  Continue leveraging the application delivery & integration strategy that works best for you • SCCM, Active Directory, Tivoli • Mirage Application Layers • ThinApp & App-V • User Installed Applications

16 Application Layers  Application Isolation • Not part of Mirage Application Layers unless used with ThinApp • Appear and function as if natively installed  Application Conflicts • Application conflicts can exist, even using Horizon Mirage Application Layers  Application Packaging • Use a Virtual Machine for Application Layer Reference CVD • Restore VM to original state using VMware Snapshot before capturing another application • Application Packages are specific to OS version & type • Start with a clean capture machine

17 Base Layer Considerations  Keep the amount of Base Layers to a minimum • Prevent image sprawl - keep image as generic as possible • The larger the image, the more data you will send across the wire  When creating Driver Libraries, download the drivers from the hardware vendor  Base Layer Applications • Include system-level software & globally-used applications  Full Disk Encryption • Exclude from the base layer image

18 Base Layer Conflicts  Base Layers can potentially conflict with software installed on Endpoints. • Older version of application in Base Layer conflict with updated application in Base Layer • Windows updates in Base Layer conflict with Endpoint application requirements • Newer updates on Endpoint conflict with versions in Base Layer  Handling Conflicts 1. Test before deployment 2. Layer Dry-Run Reports 3. Base Layer Rules 4. Base Layer Override Policies

19 Upload Policies  Upload Policy “Areas” • Protected Area – Files and folders on a device that are centralized in the datacenter • Unprotected Area – Files and folders that will NOT be centralized • User Area – Protected files and folders that belong solely to the endpoint user  Applications or data placed into the user profile are captured in the user area  Applications or data placed anywhere else are captured in the Protected Area.

20 Upload Policies  Upload Policies impact centralization & synchronization  Don’t back up what you don’t need!  Do you NEED to back up the endpoints for OS migrations? • Accelerates migration timeline & reduces storage needs for Mirage • No roll-back of Windows XP or Windows 7 Endpoint during OS Migration  Large Files • To back them up or not?

21 Steady State Synchronization – The Balancing Act  Getting the right synchronization interval is key  Network speed (LAN/WAN/VPN) • Type of connection & available bandwidth  Amount of changed data on endpoint • Data de-duplication – does it already exists (i.e. Patch Tuesday)? • Upload policies – do I need to backup all changed data? • How long does an incremental upload take?  Storage performance & capacity • IOPS • Available disk space  Endpoint availability • Stationary vs. mobile/laptop users

22 Branch Reflector  Branch Reflectors are your FRIEND • Use it on the LAN & WAN • Make sure your AD Sites & Services are configured properly • Only supports “Downstream” operations ONLY  Use desktop PC that is not assigned to a user & has ample compute/storage resources  Powered on 24/7 to support Mirage operations  Avoid using laptops, if possible • Taken home or moved between offices • If laptops are the Branch Reflector available • Use cabled connection & no power management • Ensure ample compute/storage

23 Networking  Know Thy Network! • Map it out – know bandwidth capacity and utilization of the network • Wi-Fi Considerations  Mirage Network Necessities • Quality and Class of Service/Priority Queuing/Traffic Shaping critical • Network maps and performance statistics • Understand the Mirage network usage patterns from a PoC/Pilot  What should I expect on the network with Mirage? • LAN vs. WAN centralization/synchronization • Amount of data centralized/synchronized – more data, more bandwidth

24 Networking (cont.)  Don’t forget the network path to the storage • Separation of client & storage network traffic, if at all possible • End-to-end networking (Mirage NIC out, the path, and the File Server NIC in)  Include “Downstream” Operations in planning • Base Layer/App Layers, etc.  If the network path to storage or networking is oversubscribed, Mirage will “throttle” the server. • It’s a safety net, not an design principle

25 Storage  Sizing your storage is massively important • Conduct a PoC/Pilot to help with storage sizing estimates (IOPS, Capacity) • Pilot multiple use cases and variations of desktops, not just one • The IOPS requirements will depend on multiple factors • Amount of concurrent centralizations & downstream operations • Network bandwidth • User connectivity (on and off the network) • User productivity (how often the machine is in use) • Snapshot policy  Local vs. Shared Storage • Shared storage is recommended (required for Mirage Clustering/Single Instance) • Local storage in a Mirage Cluster – it may work at first, but it will break  Place Mirage Cache on Flash/SSD where possible

26 Storage (cont.)  Single vs. Multiple CIFS shares • Better data de-duplication seen when more CVD’s are on a share • Recovery and other Single Instance Store maintenance operations can be significantly extended when using a single CIFS share • Shares with more CVDs become extremely large in size • Balance number of CIFS based on the needs and requirements of your organization  Driver libraries are stored on the default Mirage SiS • If you delete this store, your drivers are gone

27 Security  Full Disk Encryption • Enable Full Disk Encryption (FDE) that modify hard drives after Mirage integration • Decrypt FDE before any operation that modified MBR • Data files are NOT stored in an encrypted format on the Mirage Single Instance Store (SiS) when using FDE  Microsoft Bitlocker & Sophos FDE are Supported • Bitlocker - upstream/downstream operations function properly • Sophos - disk encryption supported for OS Migration  Microsoft Encrypted File System (EFS) • Encrypted files uploaded with EFS are restored with EFS  Centralization over the Internet not supported • Must use VPN connection

28 Security (Cont.)  Single Instance Store (SiS) Security • Files stored on Mirage SiS cannot be executed • Use NTFS, Share & ACL Permissions to secure Mirage SiS access • Limit data on share to ONLY Mirage-related data  SSL • Encrypts Mirage network traffic over TCP 8000 – Use it! • All or nothing • Use it for the Web & File Portals  Anti-Virus • It WILL affect Mirage Performance and Operations • Exclude Mirage Cache & Wanova.Server.Service.exe process • NAS and CIFS/SMB Filer Anti-Virus implementations are typically independent of scanning on Mirage Server

29 Operations & Administration  Delegated Administration • Delegate based on risk, job responsibility and best suited IT group to support Mirage • Roles are Active Directory-integrated – use AD groups  Operational Procedures • Run books for OS and hardware migrations, desktop backup/recovery, archiving & other Mirage operations • Run books for Help Desk - common support issues • Endpoint Centralization – Automatic vs. IT-initiated  User Self Service – File/Folder Recovery • Provide simple procedures for file/folder recovery

30 Backup & Recovery  Don’t forget the Mirage Database  Lots and lots of files and folders means longer backup windows • Restoring Mirage components will also take awhile  Integrate Mirage into corporate DR strategy • Conduct simulated Mirage recovery & document recovery procedures

31 Availability & Resiliency  Use multiple Mirage servers in a clustered configuration (N+1)  Use a Load-Balancing solution to distribute load across all Mirage Servers in a cluster  Consider a dedicated/clustered MS SQL Database

32 Sizing Considerations  Network • “You can’t drive a Buick through the eye of a needle.” • Bandwidth Speed & Overall Circuit Utilization are critical • Quality of Service/Class of Service or Priority Queuing • LAN-speed considerations  Storage • IOPS, Connection Speed/Capacity to Storage • Amount of Data • Single vs. Multiple CIFS Shares

33 Sizing Considerations (cont.)  Upload Policies • More Data = More Resources (Storage, Network) = More Time to complete a Mirage task  Differential Data • Data change impacts how much data can be uploaded in a given time period  Endpoint Availability and Connectivity • Laptops or Mobile Users - On/Off Network • Remote Users (VPN)  Consider the volume & frequency of centralization, steady state & base layer operations  Centralized vs. Distributed Architecture

34 Sizing Considerations (cont.)  Gather REAL WORLD data through effective testing & validation • Environment uniqueness impacts the design • Real-world sampling/assessment & planning is critical to sizing  Physical vs. Virtual Mirage Servers  General guidelines • Appropriately size the environment based on real world data (PoC/Pilot) implementation • Don’t size for 100% utilization – size for target of 80%  Don’t ignore the dependent infrastructure (i.e. storage & networking)
