When creating a replication target on the source appliance, a connection is established that enables secure communications between a source and replication target. This operation requires the following details:
Name of the replication target - used only to identify the target in the BUI and CLI of the source appliance.
Network IP address - the data interface of the replication target. The address must be an IPv4 address or host name. Remote replication does not support IPv6 addresses.
Target root password - to authorize the administrator to set up the connection on the replication target.
The appliances exchange keys used to securely identify each other in subsequent communications. These keys are stored persistently as part of the appliance configuration and persist across reboots and upgrades. They will be lost if the appliance is factory reset or reinstalled. The root password is never stored persistently, so changing the root password on either appliance does not require any changes to the replication configuration. The password is never transmitted in the clear because this initial identity exchange (like all replication control operations) is protected with SSL.
By default, the replication target connection is not bidirectional. For example, if an administrator configures replication from source A to target B, target B cannot automatically use source A as a target. However, the system supports reversing the direction of replication, which automatically creates a target for source A on target B (if it does not already exist) so that target B can replicate back to source A. For more information, see Reverse the Direction of Replication.
To configure replication targets, see Creating a Replication Target BUI, CLI.
