A DataKeeper job contains the endpoint information for all mirrors that are part of the job. This information includes the host name, IP address, and drive letter of each mirror endpoint.
Within a job, an IP address cannot be duplicated on more than one node. For example, in a 4-node job, nodes “A” and “B” may be configured with a private network connection, and nodes “C” and “D” may be configured with a separate private network connection. However, the IP addresses on those private networks must be unique for each node. If nodes A and B use 192.168.0.1 and 192.168.0.2 for replication, then nodes C and D cannot also use 192.168.0.1 or 192.168.0.2 for replication.
