  • Method and apparatus for managing data imaging in a distributed computer system
    Patent number: 7054890
    Abstract: A three-tiered data imaging system is used on a distributed computer system comprising hosts connected by a network. The lowest tier comprises management facade software running on each machine that converts a platform-dependent interface written with low-level kernel routines that actually implement the data imaging system to platform-independent method calls. The middle 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 tier of the inventive system comprises presentation programs that can be directly manipulated by management personnel to view and control the system. In one embodiment, the federated Java beans can run on any machine in the system and communicate, via the network. A data imaging management facade runs on selected hosts and at least one data imaging bean also runs on those hosts.

  • Method and apparatus for managing remote data replication in a distributed computer system
    Patent number: 6772178
    Abstract: A three-tiered data replication management system is used on a distributed computer system connected by a network. The lowest tier comprises management facade software running on each machine that converts a platform-dependent interface written in low-level kernel routines that actually perform the data replication to platform-independent method calls. The middle tier is a set of federated Java beans, which communicate with each other, with the management facades, and with the upper tier of the system. The upper tier of the inventive system comprises presentation programs that can be directly manipulated by management personnel to view and control the system. The federated Java beans can run on any machine in the system and communicate via the network. A data replication bean runs on each host and at least one such bean communicates directly with a management interface that is controlled by a user.
