US 6,772,178 B2 · Method and apparatus for managing remote data replication in a distributed computer system

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.

Claims22

Dependent claims

A method for managing remote data replication from a management terminal in a distributed computer system having a primary host with a first storage device connected by a network to a secondary host with a second storage device, the method comprising:

(a) running in the primary host a first federated SNDR bean;
(b) running in the secondary host a second federated SNDR bean that communicates, via the network, with the first federated SNDR bean;
(c) connecting the management terminal to the first federated SNDR bean and providing data replication commands from the management terminal to the first federated SNDR bean which thereupon controls the second SNDR federated bean;
(d) using the first federated SNDR bean to configure and manage the first storage device for data replication;
and
(e) using the second federated SNDR bean to configure and manage the second storage device for data replication.

A computer program product for managing remote data replication from a management terminal in a distributed computer system having a primary host with a first storage device connected by a network to a secondary host with a second storage device, the computer program product comprising a computer usable medium having computer readable program code thereon, including:

program code that runs a first federated SNDR bean in the primary host;
program code that runs in the secondary host a second federated SNDR bean that communicates, via the network, with the first federated SNDR bean;
program code that connects the management terminal to the first federated SNDR bean and provides data replication commands from the management terminal to the first federated SNDR bean which thereupon controls the second federated SNDR bean;
program code that uses the first federated SNDR bean to configure and manage the first storage device for data replication;
and
program code that uses the second federated SNDR bean to configure and manage the second storage device for data replication.
