# (Optional) Create a bucket for Data Optimizer

Use this task to manually create a bucket for the Data Optimizer instance.

   The Namespaces page opens.
2. On the Namespaces page, click **Create Namespace**.

   The Create Namespace panel opens.
3. Use the following steps to create a namespace:

   2. Configure **Hard Quota** to provide adequate capacity for an individual Data Optimizer instance.
   3. Set **Cloud Optimized** to **On**.
   4. Set **Versioning** to **On**.
   5. Enable version pruning older than 0 days.
4. Use the following steps to enable an access control list (ACL):
   1. In the Tenant Management Console, click **Namespaces**.

      The Namespaces page opens.
   2. In the list of namespaces, click the name of the Data Optimizer namespace.
   3. Click the **Settings** tab.

      The Settings panel opens.
   4. On the left side of the Settings panel, click **ACLs**.

      The ACLs panel opens.
   5. In the ACLs panel, select **Enable ACLs**.

      A confirmation prompt displays.
   6. Click **Enable ACLs**.
5. Use the following steps to enable the Hitachi API for Amazon S3:
   1. In the Tenant Management Console, click **Namespaces**.

      The Namespaces page opens.
   2. In the list of namespaces, click the name of the Data Optimizer namespace.
   3. Click the **Protocols** tab.

      The Protocols panel opens.
   4. Select **Enable Hitachi API for Amazon S3**.

      **Note:** Enable HTTP only if you will not be using TLS.
   5. Click **Update Settings**.
6. Specify the namespace name in the **BUCKET** parameter of the Data Optimizer configuration file, `/etc/ldo`.
