You create a replication link on either one of the systems you want to participate in the link. When you first create the link, you set these properties:
- The link name.
- Optionally, a description of the link.
- The link type. This can be active/active, outbound (for an active/passive link you’re creating on the primary system), or inbound (for an active/passive link you’re creating on the replica).
- Whether HCP should compress and/or encrypt data before transmitting it to the other system. For an active/active link, these settings apply to data being replicated in both directions on the link.
- Whether priority should be given to objects with the oldest changes, regardless of namespace, or processing should be balanced across namespaces. For an active/active link, this setting applies to both systems involved in the link.
- The identity of the other system you want to participate in the link. You can identify the other system either by domain name or by the IP addresses of storage nodes in that system.
- The port on which the other system will listen for transmissions from the system where you’re creating the link. Typically, you accept the default of 5748.
- If the system where you’re creating the link uses network address translation (NAT):
NoteIf either or both of the systems involved in a link use a NAT, the NAT or NATs must be configured for port forwarding.
- The domain name or IP addresses the other system should use to communicate with the system where you’re creating the link
- The port on which the system where you’re creating the link will listen for transmissions from the other system
When you create a link, the automatic failover and failback properties default to disabled. You cannot modify these properties during link creation.
