OIM Requirements¶

This section outlines the key requirements for the Omnia Infrastructure Manager (OIM) used to deploy HPC clusters. For more information about the supported devices and software, see Support Matrix.

Omnia Infrastructure Manager¶

Choose a server outside of your intended cluster that meets the required Storage Requirements to function as the Omnia Infrastructure Manager (OIM).
Ensure the OIM has at least 64 GB RAM. To check the free RAM size, use the free -h command. To check the disk space, use the df -h command.
Ensure that the OIM has the RHEL operating system installed with the Server with GUI Base Environment. For a complete list of supported RHEL versions, see the supported operating systems.
Ensure that Podman container engine is installed on the OIM.
The OIM must have access to the admin (PXE) network and to every configured package, container, and source repository. Internet access is required when public repositories are used; an offline deployment can use reachable local mirrors instead.
Verify that Git is installed. If not, install it using:
Run on: OIM host
```
dnf install git -y
```
All target bare-metal servers (cluster nodes) must be reachable from the OIM.
Make sure that the required Omnia ports are available on the applicable hosts. For detailed information on the required ports, refer to Ports used by Omnia.
Complete Setup the OIM to install the shared environment and initialize the deployment modules.
