{: #ceph_storage}

IBM Storage Ceph is a scalable, open, software-defined storage platform. It combines an enterprise-hardened version of the Ceph storage system, with a Ceph management platform, deployment utilities, and support services.
{: shortdesc}

If you select **IBM Storage Ceph** from the **Storage** section, configure the following details:

 | Field | Description |
 |--------------------------|----------------|
 | Display name | Enter the name to be displayed.|
 | Bucket name | Enter your existing object storage bucket name.|
 | Endpoint | Enter the endpoint URL.|
 | Access key | Enter your access key. |
 | Secret key | Enter your secret key. |
 | Connection Status | Click the Test connection link to test the storage connection. If the connection is successful, a success message appears.|
 | Designate this bucket as the ACL store | Use the toggle switch to designate this bucket as the ACL store. If you enable the toggle switch, \n An **Enable Access Control List (ACL)?** dialog appears, Click **Enable**. \n This feature applies to watsonx.data Premium, for more information see [Governance through Access Controlled Lists (AC)](https://dataplatform.cloud.ibm.com/docs/content/wsj/wx-data/gov_acl.html?context=wxd&audience=wdp&format=markdown). If you enable the toggle switch, the Associate catalog option is selected by default, with the Apache Iceberg catalog preselected. You cannot choose a different catalog for ACLs. You can designate only one storage as the ACL store per instance. After a storage is designated, this option will no longer be visible or available.|
 | Associate catalog | Enable the toggle switch to add a catalog for your storage. This catalog is automatically associated with your storage and serves as your query interface with the data stored within. |
 | Catalog type | Select the catalog type from the list. The recommended catalog is Apache Iceberg. The other options for catalog are Apache Hive, Apache Hudi and Delta Lake.|
 | Catalog name | Enter the name of your catalog.|
 | Base path (optional) <br> **Note:** This field is available only in the watsonx.data Lite instance. This field appears only when you select Apache Iceberg as the catalog type. | Enter the base path for the catalog in the object storage. This allows you to associate multiple Iceberg catalogs with a single storage. <br>**Note:** You cannot share a storage between Iceberg and non-Iceberg catalogs. |
 | Associate | Click Associate to create the storage. |

If IBM Storage Ceph is already inactive in old instances, the system will display the `Activate` button. Once you activate IBM Storage Ceph, the system will automatically remove the `Activate` button.
