Configuring connection settings for the S3 API

If you are connecting to an Archive Node using the S3 interface, you must configure the connection settings for the S3 API. Until these settings are configured, the ARC service remains in a Major alarm state as it is unable to communicate with the external archival storage system.

Before you begin


  1. Select Support > Grid Topology.
  2. Select Archive Node > ARC > Target.
  3. Click Configuration > Main .

    Configuration page for an Archive Node
  4. Select Cloud Tiering - Simple Storage Service (S3) from the Target Type drop-down list.
    Note: Configuration settings are unavailable until you select a Target Type.
  5. Configure the cloud tiering (S3) account through which the Archive Node will connect to the target external S3 capable archival storage system.

    Most of the fields on this page are self-explanatory. The following describes fields for which you might need guidance.

    • Region: Only available if Use AWS is selected. The region you select must match the bucket's region.
    • Endpoint and Use AWS: For Amazon Web Services (AWS), select Use AWS. Endpoint is then automatically populated with an endpoint URL based on the Bucket Name and Region attributes. For example,

      For a non-AWS target, enter the URL of the system hosting the bucket, including the port number. For example,

    • End Point Authentication: Enabled by default. If the network to the external archival storage system is trusted, you can unselect the check box to disable endpoint SSL certificate and host name verification for the targeted external archival storage system. If another instance of a StorageGRID system is the target archival storage device and the system is configured with publicly signed certificates, you can keep the check box selected.
    • Storage Class: Select Standard (Default) for regular storage. Select Reduced Redundancy only for objects that can be easily recreated. Reduced Redundancy provides lower cost storage with less reliability. If the targeted archival storage system is another instance of the StorageGRID system, Storage Class controls how many interim copies of the object are made at ingest on the target system, if dual commit is used when objects are ingested there.
  6. Click Apply Changes.
    The specified configuration settings are validated and applied to your StorageGRID system. Once configured, the target cannot be changed.
