#Citrix blog post – Get Up To Speed On #XenDesktop Bandwidth Requirements
Welcome to the HDX bandwidth testing blog series! In the following posts I’ll be sharing key findings and results from an extensive round of XenDesktop 5.6 / XenApp 6.5 bandwidth testing. Already using XenDesktop 7? Well then stay tuned for the last post in the series where I will be discussing that as well. Before I begin, I want to take this opportunity to thank Andy Baker and Thomas Berger for their tremendous help and guidance in managing this effort.
Part 1: The Prologue
It is not uncommon these days to have great LAN networks with what seems like unlimited bandwidth. I find myself at the office running multiple virtual desktops, uploading my files to ShareFile, all while streaming Spotify to my machine at the same time without even noticing. Even at home you have a nice fast connection just for yourself. Unfortunately many users do not have this luxury due to expensive business grade connections which are often over utilized. Overlooking this fact during a deployment can result in frozen and disconnected sessions and an overall poor user experience. This leaves IT departments frequently asking “how much bandwidth do I need for XenDesktop?”
Of course the answer to this question – in my opinion more so than most questions – is it depends. Why is that? Because it depends on what is on the screen at any given time. The amount of bandwidth consumed will be close to none when the session is idle, but can vary greatly depending on whether a user is typing, browsing a document, running a slideshow, or watching a video. Of course there is always the magic number of 20-30kbps that has been around forever, but that was before the explosion in multimedia content both on the web and now seen more frequently in applications as well . (Although I would note that we did reach and beat that 20-30kbps zone with some of our less multimedia intensive tests).
To help better answer this question our team decided to start running some tests…..a lot of tests. We measured general daily usage, took a deep dive into single application tests, and put some optimizations and best practices to the test. In part one of this blog I will be discussing the infrastructure and methodology for our first round of testing.
Infrastructure
The tests that I will be discussing were run in the environment shown below. A laptop was connected to anApposite WAN Emulator and used as the endpoint for both the manual and Login VSI tests. The emulator was used to control the bandwidth limits for each scenario that I describe later on in this blog post. The other end of the emulator was connected to a switch that was configured to send all packets in and out of the emulator to a mirrored port monitored by a server running Wireshark. This ensured all communication between the client and virtual desktop were captured without interfering with the VSI scripts. The environment infrastructure and desktop pool were also connected to the switch and communicated transparently to the laptop.
The environment was built using the product versions shown below. This is important to note as future tests are planned with XenDesktop 7 which benefits from newer codecs and algorithms for rendering. These tests were also run with the latest version of Login VSI which features more intense workloads than previous versions and a large randomized content library.
- XenServer 6.1
- Microsoft Server 2008 R2
- Windows 7 x86
- XenDesktop 5.6
- VDA 5.6.2
- Receiver 3.4 Enterprise
- Login VSI 4.0
Disclaimers
Before I begin to explain the tests that we ran I need to make a few disclaimers. The first being that quality of service (QoS) was not…

A look at Work Folders – #Microsoft, #WorkFolders, #MIM, #BYOD – via @STEALTHPUPPY
This is an interesting new feature by Microsoft. I’ve touched upon the topic in my earlier post: #Microsoft – On the right track! – #Windows, #BYOD, #Citrix
And here you have another good blog post from Aaron Parker around the topic!
Microsoft announced some interesting new features in Windows Server 2012 R2 at TechEd 2013 and one of those that piqued my interest is Work Folders. I’m not the biggest fan of Redirected Folders and Offline files, but it’s essentially the only enterprise solution Microsoft provides today for taking your data offline. Microsoft needs to provide a completely new method of syncing file data – one that is designed for todays use cases and computing environment.
Work Folders is a brand new direction for enabling access to data in offline scenarios, along the lines of Citrix ShareFile and Dropbox, but without the web and sharing features. Like most Microsoft OS features, Work Folders is tied to a specific release of Windows; however according to this Channel 9 video, Microsoft will release Work Folders for Windows 7, iOS and “other devices” (presumably Android). This is excellent news.
Here’s a short look at setting up and connecting to Work Folders using the preview releases of Windows Server 2012 R2 and Windows 8.1 – what’s version 1.0 going to deliver?
Server Configuration
For a more detailed walkthrough on deploying Work Folders, download this document: Windows Server 2012 R2: Enabling Windows Server Work Folders.
Work Folders is a component of the File and Storage Services role in Windows Server. I’ve installed Windows Server 2012 R2 into a virtual machine and am using local storage.
Once installed, Work Folders is managed through Server Manager:
Creating a new sync share is performed via a wizard which will first ask where the Sync Share will be located. This can be a new folder or an existing share – mixing user home drives and Work Folders should be possible. Note that at this time, Work Folders only supports providing users with exclusive access to Sync Share location – there is no provision for providing access to shared data. Read more…
#Citrix #XenDesktop 7 on #vSphere Validated Design Guide is available now!
Really good design guide by Citrix and blog post by Carisa Powell:
We are pleased to announce the availability of the Citrix Solutions Lab 5000-user XenDesktop 7 on vSphere Validated Design Guide.
Yes, you read that right, XenDesktop on vSphere. XenDesktop is also known to many vSphere customers as the best VDI solution for vSphere, and this design guide showcases the latest release of XenDesktop features and functionality all being hosted on a vSphere hypervisor. XenDesktop is the best of both virtual apps and desktops from a single platform, so XenDesktop is VDI, XenDesktop is app virtualization, XenDesktop is server-hosted apps and desktops, XenDesktop is secure remote access, XenDesktop is mobility…and with XenDesktop 7 you get all of this functionality from a single platform.
This design guide combines everything that is XenDesktop 7 and delivers it from vSphere to showcase how you can provide an app, desktop, remote access, and more solution for any type of user:
- VDI – XenDesktop offers a variety of VDI use cases, whether the user needs a standardized, corporate desktop that remains consistent and routine, or the user needs a personalized virtual desktop that he or she can customize to meet their business needs. This design guide validates XenDesktop Provisioning Services central image management technology for Pooled VDI on vSphere and XenDesktop Personal vDisk technology for delivering Personal VDI on vSphere.
- Server-hosted Apps and Desktops – XenDesktop also offers server-hosted apps and desktops by leveraging Microsoft Remote Desktop Shared Hosted (RDSH) technology to enable multiple users to connect and share resources from a single server. This design guide showcases XenDesktop server-hosted resources from Windows Servers on vSphere.
- Remote Access – XenDesktop leverages Citrix NetScaler appliances to provide secure, remote access from any location. NetScaler can be a virtual or physical appliance, and this design guide highlights the implementation and configurations of NetScaler Gateway virtual appliances on vSphere.
So why showcase all the features and functionality of XenDesktop 7 on vSphere? Staying true to the Citrix vision, XenDesktop continues to remain the only hypervisor agnostic app and desktop virtualization solution – including VDI, virtual apps and more. This means XenDesktop 7 seamlessly integrates with any hypervisor including Microsoft Hyper-V, Citrix…

Remote Desktop Services are now allowed on #Windows #Azure – #RDS, #TS, #XenDesktop
This is a great thing that you should have a look at and investigate how it would fit you and your organization! Finally Microsoft has changed the license model! They still have some work to be done on it though so we can run Virtual Desktops (VDI’s) as well!! 😉
Read this great blog post from lpanzano:
I’ve not seen a lot of news about this so I thought it was worth writing a short post just to remember everyone that on July 1st, Microsoft has officially changed Windows Azure licensing terms (PUR) to allow the use of Remote Desktop Services (RDS) on Windows Azure Virtual Machines. Previously this scenario was not allowed in Windows Azure. Before July 1st you could only access an Azure Windows Server VM for purpose of server administration or maintenance (up to 2 simultaneous sessions are authorized for this service).
Let’s see some details about this change:
-
To enable more than 2 simultaneous sessions you will need to purchase RDS Subscriber Access Licenses (SALs) through the Microsoft Services Provider Licensing Agreement (SPLA) for each user or device that will access your solution on Windows Azure. SPLA is separate from an Azure agreement and is contracted through an authorized SPLA reseller. Click here for more information about SPLA benefits and requirements.
-
RDS Client Access Licenses (CALs) purchased from Microsoft VL programs such as EA, do not get license mobility to shared cloud platforms, hence they cannot be used on Azure.
-
Windows ‘Client’ OS (e.g. Windows 8) virtual desktops, or VDI deployments, will continue to not be allowed on Azure, because Windows client OS product use rights prohibit such use on multi-tenant/shared cloud environments.
-
Customers can use 3rd party application hosting products that require RDS sessions functionality (e.g. Citrix XenDesktop), subject to product use terms set by those 3rd party providers, and provided these products leverage only RDS session-hosting (Terminal Services) functionality. Note that RDS SALs are still required when using these 3rd party products.

Citrix also created a good blog post on their view of the top 5 scenarios for putting XenDesktop on Azure:
Top 5 Scenarios for XenDesktop on Windows Azure
Since Windows Azure launched I have looked forward to the day Citrix would be able to work jointly with Microsoft to support XenDesktop and XenApp workloads. We are excited that today is the day we announce support for XenDesktop 7 and XenApp 6.5 on Windows Azure. Customers can now take advantage of the leading Citrix desktop virtualization solution and all of the HDX user experience goodness on Microsoft’s leading public cloud. With the announcement we’ve published two design guides (here andhere) to help get you started with your deployments.
#Microsoft – On the right track! – #Windows, #BYOD, #Citrix
I don’t know if you all agree but I find that Microsoft is making some really good strategic decisions to align themselves and be ready for the “next generation” workplace and client services. Everyone has been talking about BYOx and that everyone will bring their own device and consume business services and functions on that device in parallel to doing personal stuff.
But has BYOD taken off yet?
I personally think that it hasn’t to the extent that many thought it would, there are some companies in some countries that have adopted it for some use cases and user categories, but the majority is still struggling with it though their business apps and functions aren’t really there to support this way of working yet.
Even if they have a NetScaler or similar remote access capabilities with some sort of Desktop and App virtualization (like Citrix XenDesktop) to run the apps it’s still not enough. How do you solve the offline working scenario? And isn’t hosted apps and desktops just a legacy workaround until those business processes have been SaaS’ified? And what about “dropbox” alternatives, H: drives and G: drives, Sharepoint data etc. There is still a user data mess (read my earlier post on this) that needs to be solved and especially a “mega aggregator” tool for getting data/content and synch across devices in a secure manner (data also encrypted at rest on ALL devices and not just mobiles)…
Microsoft is kind of stepping up here I must say from a strategy point of view that makes me believe in them, even though I’ve said that no one ever will take my MacBook Air from me! Have a look at the features that are coming with Windows 8.1 to support a more “semi-controlled” or “semi-trusted” device, and the new cloud services like Azure AD, Windows Intunes offerings in combination with the online messaging and collaboration Office 365 services. And they are apparently also working on a “legacy” cloud service to offer desktops as a service (DaaS) as I wrote in a previous blog post as well.
I think that Microsoft is moving in the right direction towards offering the next generation enterprise IT services and to support the new way of working, and fast!
Have a look at these posts/articles on the news in Windows 8.1:
Everything you need, right from (the) Start
Microsoft is focused on delivering one experience across all the devices in your life. The centerpiece of that strategy and experience are the Microsoft services and apps that come right from (the) Start on your new Windows device.
This is the first blog post in a series that will highlight the apps and services driving toward this “one experience” vision. This experience comes to life through more than 20 new and improved Microsoft apps and services that come as part of Windows 8.1, including a new one that we are announcing today – Skype, right from (the) Start!

#Citrix #NetScaler #SDX Installation Overview Video
This is a pretty good “quick” video of the SDX installation! Have a look at it, and remember not to use 1Gbps interfaces only if you want to run more than 7 VPX’s on the SDX! Then go for 10Gbps interfaces or many channels/interfaces of 1Gbps to not hit the SR-IOV limit of 7/1Gbps interface! 😉
Description
12:45 screen capture with PPT overview on IP Addressing, and walking through install, IP Change for SDX’s SVM and XS IPs, licenses, and then the install of a NetScaler instance with NSIP and SNIP. This is intended to be a quick overview before you set out on a first SDX install, and is in compliment with the SDX Quick Install Guide.

Upgrading to #Citrix #Receiver for #Windows – why and how?
This is something that all Citrix admins should read! How many questions don’t U get about which version of the client to use and why etc?
This document describes the various versions of Receivers for Windows, lists the reasons for upgrading, and recommends best practices for upgrading to the latest version of Receiver based on specific circumstances.
Note: The Online Plug-in 12.x will reach end of its maintenance in March 2013. Customers using Online Plug-in with XenApp 5, XenApp 6.x, XenDesktop 4.x, or XenDesktop 5.x must upgrade to the latest version of Receiver for Windows 3.X prior to that date where practical.
Citrix Receiver is the latest Citrix software you install on Windows end points to gain access to virtualized apps and desktops. It is also regularly installed on virtual desktops to enable access to virtualized apps.
The name of Citrix client software and the built-in functions are changed over the years. The clients in common use today are the Online Plug-in for Windows 12.X and the Receiver for Windows 3.X.
Where the Online Plug-in for Windows 12.X provided Web and PNAgent support, Receiver for Windows 3.X provides additional support. It can be configured for self-service access to applications, VPN-less remote access, single sign-on the Windows, Web, and SaaS applications, and has a built-in method to check for updates.
Both the Online Plug-in and Receiver have two versions.
- The Online Plug-in Web is used solely for Web access to applications and the Online Plug-in (Full) supports Web access as well as PNA Services. The Full version supported SSO, Smart Cards, and access to apps through the Start menu
The standard Receiver for Windows, CitrixReceiver.exe, can be considered is a complete replacement for the Online Plug-in Web and largely a replacement for the Online Plug-in (Full). It can be used for web access. It can be configured to access PNA Services. And it can also be used with the latest versions of StoreFront, CloudGateway (App Controller), and Access Gateway to provide a rich set of services. It contains the latest, multithread, multi-stream HDX engine.

Choose your #Citrix #NetScaler … wisely… – via @hlouwers
This is a question I get a lot and I must say that Henny Louwers did answer it well in this blog post!
I spend a lot of my time breaking down the different models of Citrix NetScaler appliances and different Software Editions within the Citrix NetScaler portfolio.
I decided to set up a blog about this since the path is usually pretty much (lengthy but) the same. This does not mean the answer is always easy because there are a lot of questions that need to be answered.
The first thing I would like to get off my chest is the following: Stop seeing/selling the Citrix NetScaler as a replacement for Secure Gateway. It is so much more than that. I often have discussions with various engineers and consultants telling me that Citrix NetScaler is so expensive for a Remote Access solution because Secure Gateway always used to be free. No offense but a Citrix NetScaler solution belongs to the networking department, not the Citrix XenApp sys admin department. Or maybe limited.
That leads me to the first difficult thing of a Citrix NetScaler project. The adoption of the Citrix NetScaler appliances to the networking guys of an organization. They need to embrace the solution to make this a success. For some reason they too see it as a ‘’Citrix’’ solution. For that reason one of the most important meetings to setup is usually with the networking guys to try to explain the L3-L7 functionality of the Citrix NetScaler solution. When they realize it competes with F5, Juniper, Cisco, etc then we are on the right track.
NetScaler Gateway or NetScaler Standard Edition
Usually the first question of a customer is regarding something simple like replacing the Remote Access solution. Since the NetScaler is going to be the main platform for publishing Citrix publications a NetScaler Gateway can be considered as a valid option. This is when I tell a customer it would be wise to spend a little extra on the NetScaler Standard Edition since this would leverage the solution be having full load balancing capabilities (among others). When you compare prices between the NetScaler Gateway and NetScaler Standard Edition you will see that the Standard Edition will be somewhat more expensive but I for one think that it is worth the difference given the feature set that come with the Standard Edition. Of course the NetScaler Gateway can always be upgraded to a NetScaler Standard Edition (or higher) if you will.
Another feature of Citrix NetScaler Standard Edition is the ability to run Citrix Web Interface on the appliance. Honestly, I do think is not really that important anymore….
