Outcome phase II Project VRC: latest generation virtualization technology doubles Terminal Server workload capacity

PQR and Login Consultants combine their strength in Project VRC, to benchmark workloads for Terminal Server (TS) on the latest hardware and virtualization software

De Meern/Amsterdam, 1 February 2010 – PQR and Login Consultants launch the results of phase II of the independent research project ‘Virtual Reality Check’ (VRC). Based on 150 new tests, Login and PQR present their findings on the influence of hardware and virtualization software on the performance of TS and Citrix XenApp, in a new whitepaper: ‘Project VRC: Phase II’.

The Research & Development project ‘Virtual Reality Check (VRC), the Platform Performance Index’ was started early 2009 by Login Consultants and PQR. Goal of the project is analyze the developments in the application and desktop virtualization market and to present the outcomes as objective as possible.

Initiators Jeroen van de Kamp, CTO Login Consultants, and Ruben Spruijt, Technical Officer at PQR, now present – as a result of 150 additional tests – the latest findings in the whitepaper ‘Project VRC: Phase II’.  The document shows the impact of Terminal Servers on the performance of the latest hardware and hypervisors in the (virtualization) market. Spruijt comments: ‘During the second phase of the VRC project, I was surprised by the significant economies of scale, which was made possible by the new processor architecture. Without any change in the hypervisors, this lead to the a 100% increase of possible concurrent users. This is very promising for the future! Van de Kamp adds: “We see that hardware plays a significant part in the increase in scale. A little under two years ago we were careful to virtualize Terminal Servers and XenApp, but this has changed fundamentally. Project VRC’s outcomes substantiate that.

Phase I of the project did not compare hypervisors, but described their behavior in separate whitepapers. The market obviously did compare the outcomes of the different whitepapers, which is why we decided to take up the outcomes of Phase II in one single document. The hypervisors VMware vSphere 4, Citrix XenServer 5.5 and Microsoft Hyper-V2.0 have been tested on HP ProLiant DL380G6 servers equipped with Intel ’Nehalem’ Xeon 5500 processors. The Virtual Session Indexer (VSI) 2.1 made this possible. This product independent benchmark tool for  Terminal Servers  and Virtual Desktop Infrastructures, indexes the performance, base4d on the number of simultaneous working sessions on 1 machine (either virtual or physical; the number of operating systems is leading) . By doing so each platform is tested in an identical way.

People who have an interest in the project can, besides comparing the test results, also execute the tests by themselves. The used testing environment and methods are covered in the whitepaper. The VSI 2.1 tool is freely downloadable through the Login Consultants website

The Whitepaper ‘Project VRC: phase II’ is available for download via www.virtualrealitycheck.net.

Login Consultants today released VSI 2.1. Login VSI 2.1 is  a specifically designed benchmark for SBC and VDI environments. VSI loads the system with simulated user workload, and focuses on how much users can run on the system before it saturates. VSI is platform and protocol independent, and configuration is simplified and automated where possible. As a result, VSI is a turn-key benchmark: perform tests within days instead of weeks, there is no need to create the workloads first. VSI is intended to be used by VDI/SBC engineers/admins, a degree in testing methodologies is not required. The free version is called “VSI 2.1 Express”, the advanced version is “VSI 2.1 PRO”.

Changes in VSI 2.1

  • Updated VSImax 2.0 to 2.1 to improve accuracy (e.g. VSImax is reached when CPU is around 100%)
  • Switch from launching calc.exe to notepad.exe in response time measurement (calc.exe footprint is much bigger in Windows 7 and Windows 2008 R2)
  • New VSI PRO workload “MediumNoFlash” which disables the CPU intensive Flash app used in Internet Explorer
  • VSI.exe is now running native 64-bit instead of x86 when running on x64 Windows, still 32-bit IE is launched because of flash support
  • Citrix XenApp 6 support
  • Custom scripts added to the VSI PRO workload can use VSI settings through environment variables
  • It is now possible to specify a custom interval for session intervals
  • New VSI customization framework with image detection (VSI Foundation only)

Fixes in VSI 2.1

  • VSI does not generate an event when the workload is finished before logoff
  • AD Setup now generates a GPMC missing warning when running on Windows 2003×64
  • AD Setup now requires Admin right to prevent UAC errors
  • Slave Launchers can be started before the Master launcher
  • When launchers are finished, active session cleanup is performed only after choosing OK.
  • Launcher now fully supports x64 Windows
  • The CSV used with the custom command line CSV now supports a comma (,) and (;)
  • Launcher installation now work on other partitions than the systemdrive
  • Added the ability to specify a custom (language dependant/older versions) adobe windows title (PRO feature)

VSI can be downloaded from Login Consultants tools section of http://www.loginconsultants.com/downloads.

In the last week i installed a XenDesktop4 environment at a customer to build a infrastructure to make video conferencing and multimedia sessions possible.

First of all you need severals things:

  • AD Admin Account (or User with special rights in one OU) to let the Citrix AD Config Tool create the needed settings for the DesktopFarm 
  • a Windows Server 2003 to install the Delivery Controller
  • a virtuell Client ( i used Windows 7 and Windows XP SP3)

The AD Account is very important. The Tool is creating a SPN, a Group and an additional OU with the name of the farm. The SPN is needed for the virtuell Clients, where the XPsAgent will be installed. This Agent will query the AD for the Farm Settings. Later more…

The Installation of the Delivery Controller is very easy and Citrix’s setup works very fine. It install all neccessary features/roles and software automatically. It is possible that the setup need the Windows Source to install something. It also reboot the machine and restart the setup…. this works good, but the Setup asks not what to install at all. Only some components. The WebInterface and Diagnostic Facility will be installed automatically. Later more about the Web interface and the Consoles!

After choosing the components the setup will ask you about the farm and later the Setup wants to know where the new farm will be created and asks about the licensing. The Setup will start and after several Minutes it will ask to install some printers. This message appears up to 6 times. The first and second time while the setup installes the printers and againg after applying some hotfixes.

If the installation has finished you must first start the AD Config Tool to select the OU where the farm communications will be stored. If the tool runs successfully you find the FarmOU and FarmGUID in the CDS Console under the view “read-only properties”. 

DDC-Console-RO-Info

After that you can install the  XDsAgent on the vClient. Logon with a domain account! The setup should automatically find the Farm.

When installation has finished and the vClient has rebooted you can connect to the webinterface which is installed on the DDC.

Important Hints for the Setup and usage:

  • If the Farmname will not automatically displayed here you have a Problem with the SPN and the XD OU (or the user has no rights to read the OU)!
  • Do NOT use two or more network adapters with the DDC and the vClient. I got many Problems with the communication between all components!
  • You must use the .ADM-Files on the DVD (folder “configuration”) to configure the settings for the client and server!
  • define policies on the DDC for the farm to activate USB otherwise no WebCam or other non storage device will be connected (PSC – Policies)! (disabled per default!)

 

To see the Toolbar in the desktop session you must use the DesktopWeb (Directory DesktopAppliance) – WebInterface. This is a setting in that webinterface. Normal Webinterfaces (also V5.2.0) dont have this setting! Also the usb settings are not configurable with normal xenapp web interfaces.

When all settings and configurations are complete you can see in the toolbar the usb-button where you can connect the available devices.

If you want to use the Micrsoft TableCam you must first install the Microsoft Office Communicator 2007 R2 – The Device Drivers are included in that package.

Here some helpfull links from citrix KB:

 Troubleshooting Virtual Desktop Agent Registration with Controllers in XenDesktop – CTX117248

 

What i used and what runs:

  • Logitech Express WebCam + Sound
  • Logitech Fusion WebCam + Sound
  • Microsoft RoundTable Cam + Sound
  • Office Communicator 2007 R2
  • Windows Media player
  • Flash 10 ActiveX Client on alle involved devices

 

All Webcams were running with a very good performance! The Windows 7 Movie “wildlife” runs extremly good over the vDesktop!

Very impressive what XenDesktop 4 can do with such content!

I troubleshooted an ES5.2 installation and found a strange bug with the function to display the logfiles from the ez_queue’s.

The default path for the logging is:
%ProgramFiles%\Citrix\System Monitoring\Server\EdgeSight\scripts\rssh\log. When you want to view this logs from the ES-Website you will get an error: cannot find ….Scripts\rssh\log\file.log

You can see that the folder Scripts was created during the installation in lowercase and will be used in uppercase. normally it should not be a problem.

So i reviewed the logs and in all logfiles the path is called Scripts

I renamed the folder and the logs are visible on the website.

really strange!

I found several examples how to copy a complete folder with c# and i want to share this script because for me it is the best and easiest solution. it is copy from the famous web-site csharp411
I’ve added some more functions to handle different scenarios, when the folder already exists or the files already exists.

In this example I’m setting ‘overwrite = true’ in the function File.Copy(file, dest, true);

public static void CopyFolder(string sourceFolder, string destFolder)
{
    if (string.IsNullOrEmpty(sourceFolder))
    {
        throw new ArgumentNullException("sourceFolder");
    }
    if (string.IsNullOrEmpty(destFolder))
    {
        throw new ArgumentNullException("destFolder");
    }
    if (!Directory.Exists(sourceFolder))
    {
        throw new ArgumentException("Source folder does not exist", "sourceFolder");
    }
 
    try
    {
        if (!Directory.Exists(destFolder))
        {
            Directory.CreateDirectory(destFolder);
        }
 
        string[] files = Directory.GetFiles(sourceFolder);
        foreach (string file in files)
        {
            string name = Path.GetFileName(file);
            string dest = Path.Combine(destFolder, name);
            File.Copy(file, dest, true); 
        }
 
        string[] folders = Directory.GetDirectories(sourceFolder);
        foreach (string folder in folders)
        {
            string name = Path.GetFileName(folder);
            string dest = Path.Combine(destFolder, name);
            CopyFolder(folder, dest);
        }
    }
    catch (Exception er)
    {
        // Do something with this exception...
    }
}
