-. Download an archive file from an Oracle resource. The archive file includes files for creating cluster resources and custom manifests. The archive file also includes a script, and when you run the script, the script creates {oci} resources, such as DNS records, an instance, and so on.

+= About the {ai-full} and {oci} integration
 
 You can run cluster workloads on {oci-first} infrastructure that supports dedicated, hybrid, public, and multiple cloud environments. Both Red{nbsp}Hat and Oracle test, validate, and support running {oci} in an {product-title} cluster on {oci}.
 
-The {ai-full} supports the {oci} platform, and you can use the {ai-full} to access an intuitive interactive workflow for the purposes of automating cluster installation tasks on {oci}.
+This section explains how to use the {ai-full} to install an {product-title} cluster on the {oci} platform. The installation deploys cloud-native components such as {oci-ccm-full} and {oci-csi-full}, and integrates your cluster with {oci} API resources such as instance node, load balancer, and storage. 
 
-.Workflow for using the {ai-full} in a connected environment to install a cluster on {oci}
+The installation process uses the {product-title} discovery ISO image provided by Red Hat, together with the  scripts and manifests provided and maintained by {oci}.

+== Preinstallation considerations
 
-{oci} provides services that can meet your needs for regulatory compliance, performance, and cost-effectiveness. You can access {oci} Resource Manager configurations to provision and configure {oci} resources.
+Before installing {product-title} on {oci-first-no-rt}, you must consider the following configuration choices.
 
-[IMPORTANT]
-====
-The steps for provisioning {oci} resources are provided as an example only. You can also choose to create the required resources through other methods; the scripts are just an example. Installing a cluster with infrastructure that you provide requires knowledge of the cloud provider and the installation process on {product-title}. You can access {oci} Resource Manager configurations to complete these steps, or use the configurations to model your own custom script.

+.Deployment platforms
 
-Follow the steps in the _Installing a cluster on {oci-first-no-rt} by using the Assisted Installer_ document to understand how to use the {ai-full} to install a {product-title} cluster on {oci}. This document demonstrates the use of the {oci} Cloud Controller Manager (CCM) and Oracle’s Container Storage Interface (CSI) objects to link your {product-title} cluster with the {oci} API.
+The integration between {product-title} and {oci-first-no-rt} is certified on both virtual machines (VMs) and bare-metal (BM) machines. Bare-metal installations using iSCSI boot drives require a secondary vNIC that is automatically created in the Terraform stack provided by Oracle. 
+
+Before you create a virtual machine (VM) or bare-metal (BM) machine, you must identify the relevant {oci} shape. For details, see the following resource: 
+
+* link:https://catalog.redhat.com/cloud/detail/216977[Cloud instance types (Red{nbsp}Hat Ecosystem Catalog portal)].
+
+.VPU sizing recommendations
 
-[IMPORTANT]
-====
 To ensure the best performance conditions for your cluster workloads that operate on {oci}, ensure that volume performance units (VPUs) for your block volume are sized for your workloads. The following list provides guidance for selecting the VPUs needed for specific performance needs:
 
 * Test or proof of concept environment: 100 GB, and 20 to 30 VPUs.
 * Basic environment: 500 GB, and 60 VPUs.
 * Heavy production environment: More than 500 GB, and 100 or more VPUs.
 
-Consider reserving additional VPUs to provide sufficient capacity for updates and scaling activities. For more information about VPUs, see Volume Performance Units (Oracle documentation).
