In accordance with the principles of the present invention, management of a data
replication system is provided by a three-tiered arrangement. The lowest, or agent,
tier comprises Common Information Model (CIM) provider objects that reside in the
hosts providing the data replication service and that can make method calls on
the low-level kernel routines. The middle, or logic, tier is a set of federated
Java beans that communicate with each other, with the management facades and with
the upper tier of the system. The upper, or presentation, tier of the inventive
system comprises web-based presentation programs that can be directly manipulated
by management personnel to view and control the data replication system.
