The Phone Home service is used to manage the ZFSSA registration as well as the Phone Home remote support service. No user data or metadata is transmitted in these messages.
Registration connects your ZFSSA with Oracle's inventory portal, through which you can manage your Oracle equipment. Registration is a prerequisite for using the Phone Home service.
The Phone Home service communicates with Oracle support to provide:
Fault reporting - The system reports active problems to Oracle for automated service response. Depending on the nature of the fault, a support case may be opened.
Heartbeats - Daily heartbeat messages are sent to Oracle to indicate that the system is up and running. Oracle support may notify the technical contact for an account when one of the activated systems fails to send a heartbeat for too long.
System configuration - Periodic messages are sent to Oracle describing current software and hardware versions and configuration as well as storage configuration.
