#Netscaler Insight and Integration with #XenDesktop Director – via @msandbu

November 15, 2013 Leave a comment

Great blog post by Marius! 🙂

This is another one of Citrix hidden gems, Netscaler Insight. This product has been available from Citrix some time now, but with the latest update in became alot more useful. Insight is an virtual applance from Citrix which gathers AppFlow data and statistics from Netscaler to show performance data, kinda like old Edgesight. (NOTE: In order to use this functionality against Netscaler it requires atleast Netscaler Enterprise or Platinum)

Insight has two specific functions, called Web Insight and HDX insight.
Web Insight shows traffic related to web-traffic, for instance how many users, what ip-adresses, what kind of content etc. 
HDX Insight is related to Access Gateway functionality of Citrix to show for instance how many users have accessed the solution, what kind of applications have they used, what kind of latency did the clients have to the netscaler etc.

You can download this VPX from mycitrix under Netscaler downloads, important to note as of now it is only supported on Vmware and XenServer (They haven’t mentioned any support coming for Hyper-V but I’m guessing its coming.

The setup is pretty simple like a regular Netscaler we need to define an IP-address and subnet mask (Note that the VPX does not require an license since it will only gather data from Netscaler appliances that have a platform license and it does not work on regular Netscaler gateways)

After we have setup the Insight VPX we can access it via web-gui, the username and password here is the same as Netscaler nsroot & nsroot


After this is setup we need to enable the insight features, we can start by setting up HDX insight, here we need to define a expression that allows all Gateway traffic to be gathered. 
Here we just need to enable VPN equals true. We can also add mulitple Netscalers here, if you have a cluster or HA setup we need to add both nodes.


After we have added the node, just choose configure on the node and choose VPN from the list and choose expression true.

#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! 😉

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.

New v3 #AWS CloudFormation Template for #XenApp with support for #NetScaler and #StoreFront

Great info and post from Peter Bats!

Since Paul Wilson and myself first introduced a CloudFormation template in the blog  “Jumpstarting your XenDesktop Farm in AWS with a CloudFormation Template,” we’ve added support for multiple Regions and Availability Zones in a v2 version of this CloudFormation template in the blog “Announcing the Multi-Region AWS CloudFormation Template for XenDesktop”.

We are now announcing the third version of our AWS CloudFormation template which adds the new Asia Pacific Sydney region and support for StoreFront and NetScaler Access Gateway Enterprise. This release makes use of the NetScaler VPX instances available via AWS MarketPlace, and replaces Web Interface with StoreFront to be able to support all the advanced features of our latest Citrix Receivers.

Version 3 of the CloudFormation JSON template can be downloaded from here.

We’ve also made a video available for you that walks you through the whole process on Citrix TV. Check it out here.

For detailed instructions on using the v3 CloudFormation template, download the setup guide here.

Using this new template, in only a couple of hours you’ve constructed a XenApp farm in your selected Region within the AWS cloud using Netscaler and StoreFront technology. You can use the farm for a number of purposes, including:

  • Application Testing
  • Business Continuity
  • Proof-of-Concept
  • Testing XenApp performance in the      cloud
  • Learning how to manage AWS resources

We welcome your…

How does #Citrix #NetScaler SDX isolate its instances?

Ok, I received this question the other day and this article is really spot on! Get a cup of coffee and enjoy! 😉

And remember this: YOU CAN ONLY HAVE 7 INSTANCES/1Gbps NIC!!!! So if you intend to host more than 7 VPX’s on your SDX then ensure that you plan your network design if you use 1Gbps otherwise go for the 10Gbps ports and SPFS.

NetScaler SDX Appliance with SR-IOV and Intel-VTd

This article contains information about the Single Root I/O Virtualization (SR-IOV) and Intel Virtualization Technology for Directed I/O (Intel-VTd) technology and how NetScaler appliance uses this technology to achieve fully isolated high performance NetScaler instances.

NetScaler SDX Appliance with SR-IOV and Intel-VTd

Server Virtualization presents both a tremendous opportunity and a major challenge for Enterprise Data Centers and Cloud Computing infrastructure. Current Hypervisors already facilitate the consolidation of many servers that are not utilized efficiently to a smaller number of physical servers delivering better space utilization, lower power consumption, and reduced overhead costs.

Virtualization architectures are built on a virtualization layer called a Virtual Machine Monitor or Domain 0 that becomes the primary interface between a virtual machine and the physical hardware. Even though virtualization allows multiple virtual machines to share the same hardware, it also creates additional overhead and can lower server performance as it becomes the bottleneck between a virtual machine and input/output (I/O) hardware as the number of virtual machines increase.

The NetScaler SDX appliance breaks through these performance bottlenecks by leveraging next generation of I/O virtualization technology called SR-IOV as defined by the PCI-Special Interest Group (SIG). SR-IOV enabled Intel chips along with Intel VT-d enable the NetScaler SDX appliance to significantly reduce virtualized network processing overheads, and provide more secure and predictable mechanisms for sharing I/O device among multiple virtual machines.

Intel Implementation of Single Root I/O Virtualization

Intel has worked with the PCI-SIG to define the SR-IOV specification. As shown in the following image, SR-IOV provides dedicated I/O to virtual machines bypassing the software virtual switch in the Virtual Machine Manager (VMM) completely, and Intel Ethernet Controllers improve data isolation among virtual machines. Another feature of SR-IOV is a feature called Virtual Functions. These are Lightweight PCIe functions that allow a single physical port to look like multiple ports. Therefore, multiple virtual machines can now have direct assignment on the same port. This increases the scalability of the number of virtual machines on the machine through more efficient I/O device sharing.

Intel VT-d Technology

Intel VT-d is a hardware enhancement for I/O virtualization that is implemented as part of core logic chipset. Intel VT-d defines an architecture for DMA remapping that improves system reliability, enhances security and…

#Citrix #NetScaler VPX on the #Cisco 1110 Virtual Network Services platform – via @pigram86

January 28, 2013 Leave a comment

Interesting!!! 🙂

This week at Cisco live! in London, Citrix is demonstrating the Citrix NetScaler VPX virtual application delivery controller (vADC) on the Nexus 1110 Cloud Services Platform . NetScaler VPX is the industry-leading vADC and is further testimony to the expanding ecosystem for the Cisco Nexus 1000V virtual networking portfolio and the Cloud Network Services platform. The integrated Cisco-Citrix solution follows on the heels of last year’s agreement by the two companies that Cisco would reference sell the Citrix NetScaler portfolio, and Cisco’s demonstration of its Nexus 1000V virtual networking portfolio on Citrix XenServer.



The Nexus 1110 is the latest generation of appliances that started with the Nexus 1010. The Nexus 1110 helps customers that are virtualizing more of their application and security services and want to run them on a dedicated platform. For example, virtual firewalls, like our Virtual Security Gateway (VSG), complement physical firewall appliances to support virtual application deployments and VM mobility requirements. The Nexus 1110 appliance serves that need, running a range of virtual services on a platform that the networking and security teams can more directly control than the other application servers.

With Citrix NetScaler VPX integrated into the Nexus 1110 Cloud Services Platform, enterprise IT admins can scale-out deployments by enabling additional virtual NetScaler instances (VM’s) directly from the Nexus 1110. NetScaler VPX also provides feature and management consistency across physical and virtual ADC’s, as well as consistency across physical and virtual workloads that are being managed. The NetScaler…

Why only Platinum version of NetScaler SDX VPX Package? – #NetScaler #SDX #Citrix

December 4, 2012 Leave a comment

Why does Citrix only sell Platinum versions in bundles of 5 for the SDX platform? Wouldn’t it be great to be able to purchase for instance Enterprise or Standard for the VPX’s you want to setup for capabilities provided by the Enterprise version of NetScaler?



I’d like to buy that instead… what about you guys? Or does this model exist?

Access Gateway Licensing Demystified

November 17, 2012 Leave a comment

Ok, this is a good blog post from Prashant Batra and touches an area that I get so many questions about!

Access Gateway Licensing Demystified

Access Gateway discussed in this blog is the Access Gateway based on NetScaler, which is popularly referred to as Access Gateway Enterprise. Citrix has recently announced End of Life for all non-NetScaler based Access Gateway platforms, which then makes Enterprise edition, the de-facto Access Gateway.

In this blog, we will discuss the two license types used on your Access Gateway appliance, the two kinds of vServers you can set up to leverage these licenses to provide standard / advanced functionalities, and an example scenario towards the end, to help illustrate these concepts in a real scenario.

License Types

Access Gateway is licensed at two levels:

  • Platform License
  • Universal License

Platform Licenses

Every Access Gateway (VPX/MPX) comes with a…  continue reading here!
