--- title: Postinstallation storage configuration --- # Postinstallation storage configuration {#post-install-storage-configuration} You can configure persistent storage after installation by using dynamic or static provisioning to retain application data beyond the lifetime of individual containers. After installing OpenShift Container Platform, you can further expand and customize your cluster to your requirements, including storage configuration. By default, containers operate by using the ephemeral storage or transient local storage. The ephemeral storage has a lifetime limitation. To store the data for a long time, you must configure persistent storage. You can configure storage by using one of the following methods: Dynamic provisioning : You can dynamically provision storage on-demand by defining and creating storage classes that control different levels of storage, including storage access. Static provisioning : You can use Kubernetes persistent volumes to make existing storage available to a cluster. Static provisioning can support various device configurations and mount options. ## Dynamic provisioning {#post-install-dynamic-provisioning_post-install-storage-configuration} Dynamic provisioning allows you to create storage volumes on-demand, eliminating the need for cluster administrators to pre-provision storage. ## Recommended configurable storage technology {#recommended-configurable-storage-technology_post-install-storage-configuration} Review the recommended and configurable storage technologies for the given OpenShift Container Platform cluster application. **Recommended and configurable storage technology** | Storage type | Block | File | Object | | --- | --- | --- | --- | | ROX | Yes | Yes | Yes | | RWX | No | Yes | Yes | | Registry | Configurable | Configurable | Recommended | | Scaled registry | Not configurable | Configurable | Recommended | | Metrics | Recommended | Configurable | Not configurable | | Elasticsearch Logging | Recommended | Configurable | Not supported | | Loki Logging | Not configurable | Not configurable | Recommended | | Apps | Recommended | Recommended | Not configurable | where: `ROX` : Specifies `ReadOnlyMany` access mode. `ROX.Yes` : Specifies that this access mode `RWX` : Specifies `ReadWriteMany` access mode. `Metrics` : Specifies Prometheus as the underlying technology used for metrics. `Metrics.Configurable` : For metrics, using file storage with the `ReadWriteMany` (RWX) access mode is unreliable. If you use file storage, do not configure the RWX access mode on any persistent volume claims (PVCs) that are configured for use with metrics. `Elasticsearch Logging.Configurable` : For logging, review the recommended storage solution in Configuring persistent storage for the log store section. Using NFS storage as a persistent volume or through NAS, such as Gluster, can corrupt the data. Therefore, NFS is not supported for Elasticsearch storage and LokiStack log store in OpenShift Container Platform Logging. You must use one persistent volume type per log store. `Apps.Not configurable` : Specifies that object storage is not consumed through PVs or PVCs of OpenShift Container Platform. Apps must integrate with the object storage REST API. > [!NOTE] > A scaled registry is an OpenShift image registry where two or more pod replicas are running. ## Deploy Red Hat OpenShift Data Foundation {#post-install-deploy-OCS_post-install-storage-configuration} Red Hat OpenShift Data Foundation is a provider of agnostic persistent storage for OpenShift Container Platform supporting file, block, and object storage, either in-house or in hybrid clouds. As a Red Hat storage solution, Red Hat OpenShift Data Foundation is completely integrated with OpenShift Container Platform for deployment, management, and monitoring. > [!IMPORTANT] > OpenShift Data Foundation on top of Red Hat Hyperconverged Infrastructure (RHHI) for Virtualization, which uses hyperconverged nodes that host virtual machines installed with OpenShift Container Platform, is not a supported configuration. For more information about supported platforms, see the Red Hat OpenShift Data Foundation Supportability and Interoperability Guide. | If you are looking for Red Hat OpenShift Data Foundation
