Building a XenApp 6.5 Farm inside your Lab Infrastructure – (Part 1)

Recently, I am setting up a poor man’s lab of Citrix XenApp 6.5 (64 bit). The reason to call it a poor man’s lab is because of the equipment in use. Though, I am complaining about the equipment I will tell you “my way” of efficiently setting up XenApp on a desktop class  Dell machine. My configuration is as follows:

Desktop Configuration:Dell Desktop Hardware Configuration

Preparatory Steps:

  • Install Windows 2008 R2 with Hyper-V as the choice of operating system on the Desktop.
  • Connect the desktop with internet to get all the Windows Updates
  • My next big thing was to create a Windows 2008 R2 EE template to create multiple VM’s and not waste time in creating individual virtual machines
  • Create a new Virtual Machine with Windows 2008 R2 EE SP1 and install all the Windows Updates
  • Install Features such as .Net 4 and Telnet Client from the “Add Features” as its reusable component on all VM’s 
  • Enable the ICMP inbound rule under the Windows Firewall port else you would be clueless during your troubleshooting
  • Sysprep the image Selection Option OOBE === Check Generalize === Shutdown. Your VM template is ready for use

Citrix Architecture for the lab

  • Plan to install Citrix XenApp 6.5 on 4 VM’s with the following server role breakup

Virtual Machine

Role

Memory

VM1 Active Directory/Citrix Licensing/Remote Desktop Licensing 400 – 700 MB
VM2 Citrix Web Server/SQL 2008 R2 Express/File Server 400 – 700 MB
VM3 Citrix XenApp1 (Application Streaming/Publishing) Static 700 MB
VM4 Citrix XenApp2 (Hosted Shared Desktop) Static 700 MB

Note: Clubbing up of roles like I have done is strictly for lab environments. Production environments should be sized and designed in a different way

List of my Best Practices:

  • Create a reusable Sysprep template to create multiple VM’s on the fly
  • Enable the ICMP inbound rule on all VM’s else you would be clueless during troubleshooting
  • Use Dynamic Memory for all your VM’s. Predefine the values for Startup and Maximum RAM options under VM Settings. I must say this feature is a savior when building labs with restrictive resources
  • Make sure the Citrix Licensing file (*.lic) carries the exact hostname of the virtual machine as it’s case sensitive. Simply type hostname under the command prompt and copy/paste the same while generating Citrix license file from www.mycitrix.com
  • In my case, the SQL Server Express is installed on the Web server. You will have to create a custom firewall rule to open the port number 1433 for all SQL related communication between the VM’s
  • During the Citrix installation make sure you select the “Install XenApp Server” option as this option brings in the convenience of installing all the prerequisite such as RDS, IIS components etc. automatically

Though, I am not sharing the step by step information on how to install each and every role because a lot of information is already available from Citrix & Microsoft and don’t want to make the blog lengthy.

I will be writing a series of blog on topics such as:

  • Application Publishing (Applications installed locally on Citrix XenApp Server)
  • Application Streaming (Application Streaming Server/Client Side)
  • User Profile Management (Separating the user profile using Citrix Profile Management)

Hi, nice blog. Can you shed more light of this part?

Thanks
