#App-V 5.0 Capacity Planning – #Microsoft via @micheroth and @vkleinerde
This is a good article, have a look at this if you’re planning some App-V 5.0 capabilities!
The following recommendations can be used as a baseline to help determine capacity planning information that is appropriate to your organization’s App-V 5.0 infrastructure.
 Important |
|---|
| Use the information in this section only as a general guide for planning your App-V 5.0 deployment. Your system capacity requirements will depend on the specific details of your hardware and application environment. Additionally, the performance numbers displayed in this document are examples and your results may vary. |
Determine the Project Scope
Before you design the App-V 5.0 infrastructure, you must determine the project’s scope. The scope consists of determining which applications will be available virtually and to also identify the target users, and their locations. This information will help determine what type of App-V 5.0 infrastructure should be implemented. Decisions about the scope of the project must be based on the specific needs of your organization.
| Task | More Information |
|---|---|
| Determine Application Scope | Depending on the applications to be virtualized, the App-V 5.0 infrastructure can be set up in different ways. The first task is to define what applications you want to virtualize. |
| Determine Location Scope | Location scope refers to the physical locations (for example, enterprise-wide or a specific geographic location) where you plan to run the virtualized applications. It can also refer to the user population (for example, a single department) who will run the virtual applications. You should obtain a network map that includes the connection paths as well as available bandwidth to each location and the number of users using virtualized applications and the WAN link speed. |
Determine Which App-V 5.0 Infrastructure is Required
| Important |
|---|
| Both of the following models require the App-V 5.0 client to be installed on the computer where you plan to run virtual applications. You can also manage your App-V 5.0 environment using an Electronic Software Distribution (ESD) solution such as Microsoft Systems Center Configuration Manager. For more information see Deploying App-V 5.0 Packages by Using Electronic Software Distribution (ESD). |
- Standalone Model – The standalone model allows virtual applications to be Windows Installer-enabled for distribution without streaming. App-V 5.0 in Standalone Mode consists of the sequencer and the client; no additional components are required. Applications are prepared for virtualization using a process called sequencing. For more information see, Planning for the App-V 5.0 Sequencer and Client Deployment. The stand-alone model is recommended for the following scenarios:Full Infrastructure Model – The full infrastructure model provides for software distribution, management, and reporting capabilities; it also includes the streaming of applications across the network. The App-V 5.0..
- With disconnected remote users who cannot connect to the App-V 5.0 infrastructure.
- When you are running a software management system, such as Configuration Manager 2012.
- When network bandwidth limitations inhibit electronic software distribution.

Almost perfect.. #ShareFile StorageZones on Azure is now generally available! – #Citrix, #Azure
This is a great addition I must say, but some things are missing!
One thing that I’m missing is the full integration with Azure storage containers! You still have to specify a temp/cache storage location that today ShareFile controller requires to be on a CIFS share when you have multiple controllers. And if you put the controller up in Azure as well, how do you then get that CIFS share and make it highly available? There is no CIFS exposure directly from the Azure storage, you have to setup a couple of VM’s in Azure, do something like DFS to expose is.. and then all of a sudden you have a whole file service to manage there as well.. and to monitor and all of a sudden you need AD and monitoring and reporting of it.. phuuu…
So I hope that in next version we can specify an Azure storage container for that cache/temp storage as well! 😉
The other thing I’d really like to see is NetScaler support in Azure, so that we could do proper AAA/CS/LB of the controllers in Azure as well so that we can get a simple and fully cloud based service in Azure! 🙂
BYOD and a growing global workforce are generating demand for instant access to data, offline productivity and seamless collaboration from anywhere. Organizations are challenged with reconciling these forces with leveraging existing investments, protect intellectual property and meet regulatory compliance requirements – driving interest in ShareFile StorageZones. StorageZones offers IT the flexibility to store data in secure Citrix-managed datacenters in multiple worldwide locations, or on-premise within their own datacenters.
At Citrix Synergy 2013, we announced new ShareFile StorageZones options with Microsoft Windows Azure. We are now pleased to announce the general availability of ShareFile StorageZones on Azure with the release of ShareFile StorageZones Controller software version 2.2. This release includes support for Windows Azure storage containers, therefore if you have a Windows Azure account, you can use an Azure storage container for your private data storage instead of a locally maintained share. Hosting ShareFile data natively in your Microsoft Azure account helps IT build the most cost-effective and customized solution for their organization. This customer-managed solution integrates ShareFile with Microsoft Azure’s Binary Large Object (Blob) storage, a cloud service for storing large amounts of unstructured data that can be accessed from anywhere in the world via HTTP or HTTPS.
Product Overview
Azure storage is customer-managed storage hosted in the Windows Azure cloud. File uploads are initially deposited into a temporary storage area shared by all StorageZone controllers. Then, a background service copies those files to the Windows Azure storage container and deletes the local cached copy of the file(s).
Typically with CIFS based StorageZones, the Controller servers are installed on-premise in the customer’s datacenter. However, if a customer is hosting virtual machines in Azure, they could install the StorageZone Controller software on instances running in their Azure account and not necessarily on-premise.
Read the ShareFile StorageZones on Azure Storage Technical Brief and watch the video Installing and Configuring ShareFile StorageZones v2.2 with Microsoft Azure to learn more about this solution.

#Citrix and Palo Alto Networks Team to Deliver Consolidated, Multi-tenant Network Security and #ADC Services on #NetScaler SDX
This is really interesting!!
With the myriad of features that we launched in PAN-OS 6.0, you may have missed a new deployment option for Palo Alto Networks VM-Series in your data center. In addition to the support of VM-Series for VMware environments, you can now deploy the VM-Series on the Citrix NetScaler SDX platform. We launched this with Citrix officially today.
Virtualized and cloud environments require the secure and efficient delivery of the right applications to the right users using any device and from any location. To do this, you need an infrastructure that supports all aspects of application delivery (security, availability, performance and visibility) and embraces the key characteristics of cloud:
- Multi-tenancy – the ability to support differing needs of new application owners, business units or service provider customers
- Agility – the services must have the ability to be provisioned and de-provisioned on demand, with support for automation and orchestration
- Scalability – the services must have the ability to flexibly scale up, scale out capacity to meet the needs of the business
Citrix NetScaler SDX is an open, multi-services platform that addresses these requirements. The NetScaler SDX platform consolidates NetScaler application delivery controller (ADC), and best-in-class network and security services required for application delivery. Now, with the introduction of VM-Series on Citrix NetScaler, you’ll be able to provide dedicated instances of security and ADC for per application load balancing with dedicated firewalling. You now also have a complete, integrated security and availability solution for Citrix XenApp XenDesktop deployments – from secure remote access, high-availability…

#Nutanix – the ultimate Virtual Computing Platform for VDI – CBRC-like Functionality For Any #VDI Solution with #Nutanix – #IaaS – via @andreleibovici
It’s really great to see the capabilities of the Nutanix platform! Just read this great blog post by @andreleibovici around Content Based Read Cache (CBRC) and how this isn’t necessary at all on a platform like Nutanix!
Conclusion
Overtime I will discuss more about the technology behind Content and Extent Caches. For now what is important to know is that Nutanix provides a better in-memory microsecond latency benefits provided by CBRC for any VDI solution on any of the aforementioned hypervizors, for both Linked and Full-Clones. In fact, Nutanix engineers even recommend Horizon View administrators to disable CBRC because the Nutanix approach is less costly to the overall infrastructure.
It is amazing when your world turns upside down and a technology that used to be awesome becomes mostly irrelevant. It amazes me how fast technology evolves and help organizations to achieve better performance and lower OPEX.
For a long time I have discussed the benefits of CBRC (Content Based Read Cache) available with Horizon View 5.1 onwards, allowing Administrators to drastically cut-down on read IO operations, offloading the storage infrastructure and providing greater end-user experience.
Here are few of the blog posts I wrote on CBRC technology: Understanding CBRC (Content Based Read Cache), Understanding CBRC – RecomputeDigest Method, Sizing for VMware View Storage Accelerator (CBRC), View Storage Accelerator Performance Benchmark, CBRC and Local Mode in VMware View 5.1, View Storage Accelerator (CBRC) Hashing Function.
CBRC helps to address some of the performance bottlenecks and the increase of storage cost for VDI. CBRC is a 100% host-based RAM-Based caching solution that helps to reduce read IOs issued to the storage subsystem and thus improves scalability of the storage subsystem while being completely transparent to the guest OS. However, CBRC comes at a cost.
When the View Storage Accelerator feature (CBRC) is enabled, a per-VMDK digest file is created to store hash information about the VMDK blocks. The estimated size of each digest file is roughly:
- 5 MB per GB of the VMDK size [hash-collision detection turned-off (Default)]
- 12 MB per GB of the VMDK size [hash-collision detection turned-on]
The digest file creation for a large replica disk can take a large amount of time and a bulky quantity of IOPS, therefore it’s is recommendable not to run the operation, create new desktop pools, or recompose existing pools during production hours.
CBRC also uses a RAM to manage the cached disk blocks. The per-VMDK digest file is also loaded into memory. That is the reason why CBRC should not be enabled under memory-overcommit environments. If a host is memory over-committed and CBRC is enabled – the memory pressure is increased as CBRC also uses memory for the cache. In such cases, the host could experience increased swapping and the overall host performance could be impacted.
Whilst I wrote about CBRC benefits, I also received numerous negative comments about the technology, including lack of support for full-clone desktops, being unsupported for layering tools like Unidesk, and taking too long to generate new hashes for every replica.
CBRC is a platform feature (vSphere), however it is only enabled and available via Horizon View. Other VDI products such as XenDesktop or vWorkspace cannot utilize the feature.
Nutanix suppress the need for CBCR, providing similar functionality to any VDI solution running on top of vSphere, Hyper-V or KVM. Nutanix has a de-duplication engine built into the solution that works real-time for data stored in DRAM and Flash.

#VDI Calculator v5 is Now Available with Major New Features – #IaaS, #Storage, #BYOD via @andreleibovici
This is awesome! Great work by @andreleibovici!
I am happy to announce the General Availability of the new VDI Calculator v5. This new version is the single biggest release since I started delivering the calculator. I have completely re-architected the way the calculator works, allowing multiple types of desktops to be configured in a single calculation for a single solution.
All existing features have been retained and will work in the exact same way you are used to, but you now have the ability to select different options for different types of desktops or desktop pools.
As an example, you may choose Desktop Type 1 to be a ‘student’ desktop using Linked Clones with 10 different pools; conversely you may choose Desktop Type 2 to be a ‘professor’ desktop using Full Clones with 5 individual pools. This new calculator gives you much more granular control over your calculations eliminating repetitive tasks when sizing larger environments.
To enable multi-desktop pool calculations just select ‘-’ and ‘+’ in the top bar menu.
Another additional feature is what I call ‘Ask for Help‘. During the application session when you select the Update option a new screen will show up asking if you would like to be contacted by VDI solutions vendors that can help reduce costs, improve performance or improve manageability of your VDI solution. If you are interested…

#Nutanix #Prism GUI Interactive Mock-Up Available – via @VirtuallyGeeky and @andreleibovici
Wow, this is great!
Nutanix Sr. Systems Engineer, Tim Federwitz (@VirtuallyGeeky), created a nice interactive mock-up of the Nutanix Prism Administrative Interface.
In Tim’s own words, “I have created a VERY simple, but somewhat functional, slightly interactive look at the Nutanix Prism GUI (the Nutanix Web Console). You can use it from pretty much any device, including mobile phones and tablets. Click or tap on the various items in the GUI to navigate around the different screen captures. The screenshots are all static, of course, but at least you get to see the different screens and features.
It is still in its infant stage as I threw it together in a few hours last Sunday night. I plan on finishing up the screens I didn’t have time for, but feel free to use it as it comes together. I am “releasing” it early as there seems to be a LOT of interest in something like this.
I really created it to easily show potential customers what the Web Console looks like and highlight some of the features and ease of use that it brings. Along with showing how VM centric and granular…

Performance Tuning Citrix Storefront 2.x – #Citrix, #StoreFront via @PeterSmali
Another great blog post from my colleague Peter Smali!
Performance Tuning Citrix Storefront 2.x
First of all I would like to thank Sandbu who came up with an extra performance tuning trick that I have been testing for a while now.
In this post I’ll be demonstrating an updated version of Sandbu’s due some small changes since the introduction of Citrix Storefront 2.x
As we all are aware of, Citrix Storefront is fully dependent on IIS to work, but it is really suffering of some perfromance issues that surely most of us who have been testing or implementing it are aware of. So Let’s give Storefront a new perfromance birth by doing the following
Attention! Take a backup of all files you are going to modify before doing this! And Remember that Citrix Systems does not support this!!
1. Enable Socket Pooling (pooledSockets=”on”)
Open your C:\inetpub\wwwroot\Citrix\Storename\Webweb.config file as administrator and chenge pooledSockets=”off” to pooledSockets=”on”
By enabling socket pooling, Storefront maintaines a pool of sockets instead of creating a new socket each time a new user connects to Storefront, this will give a better performance for SSL based traffic.
2. Changing the application pool to always running (Windows Server 2008 R2)
If you are running Storefront on Windows Server 2012, there is already a new feature implemented in IIS called always running on the application pools but if you are still Windows Server 2008 R2 as I do then you need to do some manual changes…
But if you are still running Windows Server 2008, then you need to do the following:
2.1 Download and install Application Initialization Module for IIS 7.5. A reboot may be required to finish the installation process…
2.2 Open the C:\Windows\System32\inetsrv\config\applicationHost.config on the storefront server as administrator and locate the following setting <configuration><system.applicationHost><applicationPools> and add thealways running paramter startMode=”AlwaysRunning” on each of following application pools
•Citrix Delivery Services Authentication
•Citrix Delivery Services Resources
•Citrix Receiver for Web
•Citrix Delivery Services
The result may look like this:
add name=”Citrix Delivery Services Authentication” autoStart=”true” managedRuntimeVersion=”v2.0″ managedPipelineMode=”Integrated” startMode=”AlwaysRunning”>
2.3 Now locate <configuration>…

And you can also check this tuning blog post:
Finetuning a Citrix StoreFront deployment
And also ensure that you intelligently load balance your XML brokers, my suggestion is to use content switching in combination with load balancing to get a more optimal solution in place.
Ensure that you DON’T use FQDN’s when you add the XML broker name into the Delivery Controllers config of the StoreFront Store!! Use NetBIOS names, and NOT like farm1.company.com, rather specify “farm1″ and then ensure that the StoreFront server can resolve “farm1″ to your CS VIP, that will speed enumeration up a lot due to that StoreFront first checks via NetBIOS/WINS which isn’t that optimal!
Content Switching instead of Load balancing of XenApp XML brokers? – #XenApp #NetScaler #CS #LB
Happy StoreFront’ing!

How to: Create Desktop Appliance site on StoreFront – #Citrix, #StoreFront, #ThinClient
I guess that some of you out there by now are using Thin Clients and some are using Desktop Appliance site functionality in the old Web Interface for these thin clients that are XenApp- or XenDesktop-ready.
So now you have or are thinking on how to setup this on StoreFront!
Citrix has A LOT of work to do in order to ensure that StoreFront becomes a stable and enterprise ready! There are so many tweaks and configurations needed in config files etc. that just isn’t ok! Add them into the console! It’s not hard, even I could code in some menus, forms windows and trigger the underlying PowerShell scripts!
But back to the topic, how do we configure Desktop Appliance site in StoreFront? Well, first we need to have a look at the following edocs articles that explain how to do it:
Desktop Appliance sites – And the most important in this article is the bottom that details WHAT DOESN’T WORK!
Important considerations
Desktop Appliance sites are intended for local users on the internal network accessing desktops from non-domain-joined desktop appliances. When you decide whether to use Desktop Appliance sites to provide users with access to your stores, consider the following restrictions.
- If you plan to deploy domain-joined desktop appliances and repurposed PCs, do not configure them to access stores through Desktop Appliance sites. Instead, configure Citrix Receiver with the XenApp Services URL for the store. For more information, see XenApp Services URLs.
- Desktop Appliance sites do not support connections from remote users outside the corporate network. Users logging on to NetScaler Gateway cannot access Desktop Appliance sites.
How do you release this and don’t support connecting through a NetScaler Gateway? Then you miss the whole point of SmartAccess, you cannot trigger EPA (host checks) for instance to control ICA/HDX features like drive mapping etc. internally. And you cannot have thin clients on the Internet that connects into the enterprise through NetScaler Gateway!
Next you should read this article that details the PowerShell madness 😉
Configure Desktop Appliance sites
I won’t go into details of the article above but rather show you how it’s done and with some examples of arguments to pass to the PowerShell scripts.
Step one is to log on to your StoreFront server, and just to show you our current setup is that we have one Receiver for Web (RfW) sites used for browser access into StoreFront:
From a Store perspective you can see that we have one (1) store that the RfW site exposes:
