During installation if you get an error message stating that the temp folder does not have enough space, try executing this command with the -is:tempdiroption, where is the absolute path of an existing directory.

./ManageEngine_DDI_xxxx.bin -is:tempdir

For non-x11 machines, use the following command:

./ManageEngine_DDIr_xxxx.bin -i console

License components in DDI Central

Clusters in ManageEngine DDI Central

Clusters are logical groupings of servers - DNS, DHCP or both organized for identification and administrative purposes. These clusters operate independently of other clusters configured within DDI Central. Each cluster you add has its own internalized  IP address plans, IP inventory,  IP Address Manager, DNS manager and DHCP manager.

A single cluster can accommodate any number of DNS servers and DHCP servers. However, ManageEngine DDI Central enables you to add only one Primary DHCP server for each cluster and the rest of DHCP servers act secondary servers configured under DHCP failover configurations.

Essential Plan:

The Essential plan includes one DNS cluster and one DHCP cluster. With the single DNS cluster, you can add up to three DNS servers into the DDI Central console. Similarly, the single DHCP cluster allows for the addition of up to two DHCP servers.

These servers can be grouped together within a single cluster or distributed across multiple clusters in any combination as per your preference. There is no restriction on the number of clusters you can create.


Professional Plan:

The Professional plan provides two DNS clusters and two DHCP clusters. This way you can add up to six DNS servers and four DHCP servers in total. You have the flexibility to organize these servers by grouping them into a single cluster or by creating multiple clusters. You can configure the clusters in any combination that suits your needs, with no limit on the number of clusters.

You can also purchase additional DNS clusters, DHCP clusters, subnets, zones, and users as add-ons. Please refer the ManageEngine Store page to check the prices of DDI Central add-ons.

Once installed, DDI Central runs in evaluation mode for 30 days. You can obtain a registered license for DDI Central at any time during the evaluation period by contacting DDI  Central Support. If you have not upgraded to the Licensed Edition by the end of the evaluation period, DDI Central evaluation license expires and you will have only read-only access.
