We recommend that you install DCImanager on a dedicated server. You may install the panel on a virtual machine based on hypervisor virtualization, but we didn't test this scenario in the enterprise environment. Dot not install DCImanager on virtual machines based on container virtualization due to network limitations.
Note
The server where you want to install DCImanager must be in the same broadcast segment with the servers that you will manage in the panel.
Supported operating system — CentOS 7 x64. Supporting only one operating system allows reducing the number of testing tasks that the QA performs and improves system stability.
Note
Install the panel on the server with the latest minor version of the operating system.
Do not change the major version of the OS.
Note
We strongly recommend a clean install of DCImanager. To ensure the best software performance, do not connect any third-party repositories.
When you install the panel on CentOS 7, use XFS as the file system.
Allocate 100-150 Gb for the root partition for DCImanager files and OS templates. OS templates use about 80 Gb. 10-15 Gb for every Windows template and about 100 Mb for every Linux template. The templates are kept in the directory of the root partition /DCI/.
