diskRedundency is a DisplayString reporting the state of the gateway's local disk redundancy feature, alerting when it is not configured or has encountered an error. An admin who assumes their gateway has mirrored/redundant local storage should check this object to confirm redundancy is actually active, since a misconfiguration here means a single disk failure could cause data loss. For example, "Alert: Disk Redundancy: Error" on a gateway the admin believed had mirrored disks would reveal the redundancy feature has broken and the box is now running on a single unprotected drive.
