Make sure that no single server is overloaded. For information on load balancing mechanisms,
see the
Citrix Web site (http://www.citrix.com)
.
Is the Novell Client installed on the Citrix server?
If the Novell Client is not installed on a Citrix server, the Citrix server session might crash
during login. To avoid this issue, see
“Tasks to be Performed After Deploying the Agent on
Citrix Servers” on page 12
.
Do you plan to use the DLU policy? If you do, are the profiles volatile?
If there is more than one Citrix server in a farm, you must use the volatile DLU and Roaming
Profile policies to enable the users and their profiles to exist on all the servers in the farm. If
you do not use the volatile DLU and Roaming Profile policies, a profile synchronization issue
might exist among the servers.
Do you have a mechanism to handle idle and disconnected sessions? If you do, how often is it
used?
The idle and disconnected sessions should be periodically logged out to enable the ZENWorks
events such as memory release and policy unenforcement to happen. Otherwise, the server
might have high memory consumption.
Are the Citrix servers used only to distribute applications or they are also used as terminal
servers?
You must deploy ZENworks 10 Configuration Management on Citrix Server only if you want
the Citrix server to be used as a terminal server in addition to distributing applications.
However, if you only intend to distribute applications, create thin client bundles and assign
them to devices or users
1.2.2 Factors Influencing Scalability
The main physical factor that govern the scalability of the Citrix servers is the RAM. The majority
of operations are performed by three services: zenworksWindowsService, ZenNotifyIcon, and
zenUserDaemon. The RAM consumption depends on the number of sessions and the number of
effective assignments that each session has.
For the minimum hardware recommendations, refer to the
Citrix Web site (http://www.citrix.com)
.
If you can provide hardware that exceeds these recommendations, your system will perform better.
Additional processing power and faster drives can make the systems more responsive.
The other factors that you need to consider include:
Device refresh frequency
Bundle schedules
System requirements
1.2.3 Scale Numbers
The information will be available for ZENworks 11 Configuration Management product after the
product is released.
