Citrix NetScaler Traffic Domains are a way of segmenting network traffic for different applications or even tenants. You are able to use a traffic domain to create fully isolated network environments on a single NetScaler instance. An instance is a single appliance or a HA setup of two appliances.
Citrix NetScaler Traffic Domains were introduced with NetScaler 10.0. At first NetScaler Traffic Domains started as a somewhat hidden feature which you could only configure by CLI. As of version 10.1 Traffic Domains are fully configurable in the NetScaler GUI which makes it a lot simpler to use.
In a way NetScaler Traffic Domains could compete with the NetScaler SDX platform. With Traffic Domains we segment networks on a single NetScaler instance instead of the SDX where we create a virtual appliance per network segment.
If you are like me and you have been using Apple OSX for a while you might notice that the Mail application has the tendency to slow down after a while. Since Mavericks OSX Mail it also consumes a huge amount of memory.
After searching on the Apple support forum I finally found a solution that solved most of my memory usage and performance issues with Mail.
I’m verry happy to announce that since the 10.1 build 122.11 all is fine again and there is no need to change Java settings. If you are not able to upgrade right now please continue reading.
Normally I’m not all that in to short articles about fixing bugs but this one is nagging so many people I couldn’t resist in jumping in.
Some time ago I started running into issues with the Citrix NetScaler Java applets build in to the GUI. I ignored it for a while because I’d always had my own laptop with me that worked every single time . So here I was thinking I was so smart because I had the only working system in the world……. But then one day it just stopped working, it would load the applet up to 1% and then froze.
With the release of Citrix XenDesktop 7 two provsioning methods are now available which fully support hosted shared (HDC) and hosted private (HDC). The first provisioning method is Citrix Provisioning Services (PVS) and the second is Machine Creation Services (MCS).
There are a couple of important differences between the two provisioning methods which you need to know before choosing the right method for your design. In one of my earlier articles I showed a decision tree which helps choosing between both methods. I would recommend to read this great article about storage resource usage, by Nick Rantalan, as well.
This article focusses on a very important difference between Citrix Provisioning Services and Machine Creation Services, Advanced Image Management.
Advanced Image Management
Advanced Image Management (AIM) is more than simply assigning an image to a specific machine or a group of machines. It’s about a proper way of upgrading and assigning images according to DTP principles in a simple and time efficient manner. Automation plays an important part of AIM as it saves time and more importantly leaves out the possibility of human errors. Andrew Morgan wrote an excellent article about why you want to prevent human errors by using automation.
PVS offers great image versioning functionality, automated DTP and even automated image updates with the integration of third party solutions like Microsoft System Center Configuration Manager. This Citrix article explains the functionality in fine detail.
Citrix XenDesktop 7 VDA
This will be a short article about an issue I ran into automating the Citrix XenDesktop 7 VDA installation.
As described on the Citrix edocs a silent install of the XenDesktop 7 VDA should be really straightforward. This is exactly what I was seeing when installing the VDA on Microsoft Windows 7, Windows 8 and Windows Server 2012.
Citrix XenDesktop 7 is probably one of the biggest product releases by Citrix ever. The consolidation of two of the strongest products, XenApp and XenDesktop into one single product is a huge step forward on so many levels!
For those of you who worked with me or who I had the honor to discuss IT in general, know that I focus on simplicity. I can get really irritated about products with great functionality but are managed with terrible management tools and a lot of different consoles. This is why I love products like SMS Passcode and RES Software products.
For what I’ve seen in the latest announcements and while testing preview releases of XenDesktop 7 (also known as Excalibur), this really is a product that comes close to true simplicity. I’m really happy with the consolidation of products, features and consoles.
This article is not going to be a “what’s new and hip style” article, there are plenty of those out there. What I want to show you is how much simpler this release makes our lives on a product and architectural level. Not only on the implementation side but especially on the management side.
