# Install the Omnia Control Plane

## Typical layout of a HPC cluster supported by Omnia 1.1.1
## Typical layout of a HPC cluster supported by Omnia 1.1.2
Using Omnia 1.1.1, you can provision and monitor hardware devices such as servers, storage devices, network switches, and InfiniBand switches in an HPC cluster. To enable Omnia to provision or configure the supported hardware devices, Omnia requires the following connections to be made available in your HPC cluster environment.

## Prerequisites to install the Omnia Control Plane version 1.1.1
* Ensure that a stable Internet connection is available on management station, manager node, login node, and compute nodes.
* CentOS 8.4/ Rocky 8.4 is installed on the management station.
* To provision the bare metal servers, go to the [ISODirect](http://isoredirect.centos.​org/centos/7/isos/x86_64/) and download the **CentOS-7-x86_64-Minimal-2009** ISO file or the [Rocky Linux](https://rockylinux.org/) and download **Rocky 8.4**.
* CentOS 8/ Rocky 8 is installed on the management station.
* To provision the bare metal servers, go to the [ISODirect](http://isoredirect.centos.​org) website and download the appropriate ISO file or the [Rocky Linux](https://rockylinux.org/) and download **Rocky 8**.
* For DHCP configuration, you can provide a host mapping file. If the mapping file is not provided and the variable is left blank, a default mapping file will be created. The provided details must be in the format: MAC address, Hostname, IP address, Component_role. For example, `10:11:12:13,server1,100.96.20.66,compute` and `14:15:16:17,server2,100.96.22.199,manager` are valid entries.
>> __Note:__
* In the *omnia/examples* folder, a **mapping_host_file.csv** template is provided which can be used for DHCP configuration. The header in the template file must not be deleted before saving the file.
