1.0 Primary Server Requirements
Ensure that the server where you install the Primary Server software meets the following requirements:
NOTE:The operating systems listed below are the ones on which the ZENworks Primary Server software can be installed. The list does not necessarily represent the operating systems that ZENworks Patch Management can update.
For this list, see the following links:
-
Legacy Patch Feed: ZENworks Patch Management Content Report (Legacy Patch Feed).
-
Advanced Patch Feed: ZENworks Patch Management Content Report (Advanced Patch Feed).
NOTE:ZENworks no longer supports Windows Server as a Primary Server from version 24.2 onwards. For more information, see End of Support for Windows Primary Server.

Server Usage |
Your server might be capable of handling tasks in addition to the tasks that a Primary Server performs. However, we recommend that any server where you install the Primary Server software be used only for ZENworks. |
For example, you might not want the server to do the following:
|
Operating System Linux |
|
IMPORTANT:
|
Processor |
Speed:2.0 GHz or faster Type: Quad-core or faster |
|
RAM |
16 GB minimum |
16 GB for 3000 devices. Add 1 GB RAM for every additional 3000 devices. If you are using Vertica, please refer to Vertica system requirements. |
Disk Space |
80 GB for installation. Depending on the amount of content you need to distribute the space. For ZENworks database, add 10 GB for every 1000 devices and for Audit database add 10 GB for every 5000 devices. 500 MB is recommended for the tmp directory. This disk space is required for rebuilding and editing the packages. Patch Management file storage (downloaded patch content) requires at least 25 GB of additional free disk space. All content replication servers also require this same amount of additional free disk space if Patch Management is enabled. If you use Patch Management in additional languages, each server also requires this additional amount of free space for each language. |
Because the ZENworks database file and ZENworks content repository can each become very large, you might want a separate partition or hard drive available. For information on changing the default content repository location on a Windows server, see For Linux servers, you might want the /var/opt directory to be located on a large partition. This is where the database (if embedded) and content repository are stored. The /etc directory requires less space. |
DNS Resolution |
The servers and workstations in the Management Zone must use properly configured DNS to resolve device hostnames; otherwise, some features in ZENworks will not work properly. If the DNS is not properly configured, the servers cannot communicate with each other, and the workstations cannot communicate with the servers. Server names must support DNS requirements, such as not including underscores; otherwise, ZENworks login fails. Acceptable characters include the letters a-z (uppercase and lowercase), numbers, and the hyphen (-). Non-english characters are not supported. NOTE:If the host name of a Linux Primary Server contains upper case characters, the server host name should be included in the /etc/hosts file located on that server. |
|
IP Address |
The server must have a static IP address or a permanently leased IP address in the case of DHCP configuration. An IP address must be bound to all NICs on your target server. |
Installation hangs if it is trying to use a NIC that does not have an IP address bound to it. |
Firewall Settings: TCP and UDP Ports |
Many TCP and UDP ports are opened by the ZENworks Installer during installation. If a port required by ZENworks is in use, the ZENworks Installer prompts you to configure an alternate port. IMPORTANT:If the firewall is disabled during installation or upgrade, ensure that you manually open the ports in the firewall settings when the firewall is enabled. |
For the list of TCP and UDP ports and how ZENworks uses them, see ZENworks TCP and UDP Ports. |
Supported Hypervisors |
ZENworks managed device software can be installed on the guest operating systems (VMs) of the following hypervisors:
