Configuring connection settings for S3 API

There are a number of settings you must configure, before the Archive Node can communicate with an external archival storage system that connects to the StorageGRID Webscale system through the S3 API.

Before you begin

About this task

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.


  1. Select Grid.
  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. Clear to disable endpoint SSL certificate and host name verification for the targeted external archival storage system. Only clear the checkbox if the network to the external archival storage system is trusted. If another instance of a StorageGRID Webscale system is the target archival storage device and the system is configured with publicly signed certificates, you do not need to clear the checkbox.
    • Storage Class: Select Standard, the default value, for regular storage, or Reduced Redundancy, which provides lower cost storage with less reliability for objects that can be easily recreated. If the targeted archival storage system is another instance of the StorageGRID Webscale system, Storage Class controls the target system's dual-commit behavior.
  6. Click Apply Changes.
    The specified configuration settings are validated and applied to your StorageGRID Webscale system. Once configured, the target cannot be changed.
