Best Practices for Deploying
ZENworks on a Citrix Server
This section describes the items you need to consider when deploying Novell ZENworks 10
Configuration Management on a Citrix server. This information is intended to supplement the online
resources that Novell provides to give you a better understanding of the design-related topics and
requirements when deploying a Novell ZENworks 10 Configuration Management solution on a
Citrix server.
ZENworks Configuration Management is also supported by other documentation (in both PDF and
HTML formats) that you can use to learn about and implement the product. For additional
documentation, see the ZENworks 10 Configuration Management SP3 (10.3) documentation (http://
www.novell.com/documentation/zcm10/index.html).
The information in this document is organized as follows:
Section 1.1, “Understanding the Need for Integrating ZENworks and the Citrix Server,” on
page 9
Section 1.2, “Gathering Critical Information for Design Activities,” on page 10
Section 1.3, “Performing Lab Tests and Validation,” on page 12
Section 1.4, “Deploying the ZENworks Configuration Management Agent on Citrix Server,”
on page 12
Section 1.5, “ZENworks Configuration Management Agent Architecture,” on page 12
Section 1.6, “ZENworks Configuration Management Tuning Parameters,” on page 13
1.1 Understanding the Need for Integrating
ZENworks and the Citrix Server
When ZENworks and the Citrix Server are properly integrated, these powerful solutions provide a
functionally rich and manageable solution that is not possible when they are implemented in
isolation. It is important to provide additional functionality without losing the functionality or
reliability of either of the components.
By integrating Novell ZENworks Configuration Management and the Citrix Server, you achieve the
following benefits:
Improved application accessibility and manageability
Strengthened security through Patch Management
Improved compliance through Asset Management
Improved remote access of applications that are on the Citrix server
Allows you to gain simple and one-click access to the applications on the Citrix server. Having
all your local and remote software in one place allows you to reduce complexity and increase
productivity.
Management of the Citrix servers

10 Deploying ZENworks on a Citrix Server Best Practices Guide
novdocx (en) 16 April 2010
Patching of the Citrix servers and the applications hosted on the Citrix servers
Load balancing of the Citrix servers
Availability of support for the Citrix Server farm that has servers that are a part of an Active
Directory forest or a workgroup
1.2 Gathering Critical Information for Design
Activities
You need to gather information to help you design your specific implementation for deploying
Novell ZENworks 10 Configuration Management on a Citrix Server.
Review the following sections:
Section 1.2.1, “Performing a Technical Assessment,” on page 10
Section 1.2.2, “Factors Influencing Scalability,” on page 11
Section 1.2.3, “Scale Numbers,” on page 11
Section 1.2.4, “Ports Used by the ZENworks Agent,” on page 12
1.2.1 Performing a Technical Assessment
You need to perform a technical assessment to review what you already have, identify what you
need, and document your requirements.
You also need to have a good understanding of the existing infrastructure. To do this, you should
hold a set of workshops or meetings to obtain all the information you need.
The two main results from a technical assessment are documentation on your findings, along with a
set of tasks that you need to perform. Information that you should gather includes the following:
Which version of Citrix Server should you use?
For more information on the supported versions of Citrix Server, see the ZENworks 10
Configuration Management Installation Guide (http://www.novell.com/documentation/zcm10/
index.html).
What is the maximum number of user sessions per server that can be active on Citrix Server?
If the maximum number of user sessions per server is more than the recommended number, try
adding more servers to the Citrix farm. We plan to provide such recommendations for the
ZENworks 11 Configuration Management product after the product is released.
Is user-based management used?
If it is used, a policy or bundle must be assigned to the users only if the policy or bundle is not
applicable to all the users logging in to the server. However, if the policy or bundle is applicable
to all the users logging in to the server, assign it to the device instead of assigning it to all the
users.
For example, if there are 150 bundles that are assigned to the users and 50 bundles are common
to all the users logging in to a device, assign these 50 bundles to the device instead of the user.
Are servers available in the Citrix farm? If they are, how many servers are available and are
these servers load balanced?
