 * The device credentials are stored in **idrac_credential**, **ethernet_credential**, **infiniband_credential**, and **powervault_me4_credential**. The **node_credential** stores the credentials of nodes in the cluster. 
 * Four groups are created under **node_inventory**-manager, compute, login, and nfs. All nodes in the inventory are to be added to these groups from the AWX UI by the user.
 * iDRAC, networking switches, InfiniBand switches, and PowerVault storage devices can be configured using the respective templates: **idrac_template**, **ethernet_template**, **infiniband_template**, and **powervault_me4_template**. **deploy_omnia_template** is used to deploy Kubernetes and Slurm on the compute nodes.
