The Citrix NetScaler documentation script version 2 has been a huge success from the moment Carl announced during Citrix Synergy last may. The script has been downloaded over 1.500 times already and we still see a daily demand for it. I’ve also received a huge amount of response with new ideas or just a basic thank you, all of this gave me the energy to start working on a new release. This was supposed to be a release with some new requested functionality but in the end the script has been completely rewritten from start to end.

Before I start with explaining what has changed I want to point out that, although I started this script, this truly has been a team effort. The script wouldn’t have been this great if it wasn’t for Carl Webster and Iain Brighton. Webster developed an amazing PowerShell template to get started with documenting and outputting to Microsoft Word. Iain has written all of the functions I use in the script to make sure I’m getting all the values out in a way it’s readable.

Please have a look at the team page to see a list of everyone who helped me develop and test the script.

Citrix NetScaler Traffic Domains ins and outs

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.

Citrix NetScaler 10.x java applet hangs while starting

Citrix NetScaler 10.x java applet hangs while starting

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.

Citrix NetScaler sizing guide

NetScaler Sizing Guide intro

About a year ago Citrix started with the NetScaler Tri-Scale method to scale up, in or out the Citrix NetScaler platform. Although this sounds great and gives you an option to pay-as-you-grow we all understand that we should take proper care for initial sizing. Doing so makes sure your users won’t be disappointed and plain simply pay less $$$.

My focus for this article is small to midrange sized Citrix NetScaler platforms up to the MPX 8600 6 Mbit/s. My experience is based on projects within the Netherlands and unfortunately for me this is as big as it gets. This doesn’t mean you can’t use the information when sizing larger platforms. This is also the reason why you will not find any information about clustering in this article.

This article is a follow up on two earlier articles mainly focused on the performance and sizing of a virtual (VPX) Citrix NetScaler Access Gateway, now called NetScaler Gateway.

This leads to questions about why there is a difference in theoretical and practical numbers. I’m not Google and therefore can’t answer them all but I will try to answer some of them.
