With x440 capabilities such as system partitioning, you can migrate and consolidate workloads across systems for improvements in systems management and resource utilization.

This approach is typically appropriate for implementations of key packaged applications such as SAP, PeopleSoft, and Siebel, where minimal integration with other applications and data is required. LAN file/print servers using Windows 2000 or Novell NetWare solutions represent another opportunity area for consolidation activities and savings.

Storage consolidation is combining data from different sources (same or disparate types) into a single repository and format. This means that storage is viewed as an enterprise resource, where centralized disk space is used to supply the storage for the servers of the enterprise.

Additional benefits can be gained through data integration and application integration. While these are often more complex projects that require extensive analysis, planning and implementation, they can provide significant return-on-investment.

￿Data integration

Data Integration involves physically combining data from different sources across the enterprise into a single repository and format. The result is that the merged data can reside on fewer servers and more centralized and consistent storage devices, greatly lowering the total costs.

When all corporate data resides on the same system, consolidation allows high levels of security and data integrity that are nearly impossible to achieve in a distributed environment. In addition, data sharing throughout the enterprise is vastly simplified.

The data can be file data such as Windows 2000, Novell, or Linux consolidated to a single network operating system. Also, multiple types of databases, such as DB2, Informix, Oracle, Sybase, etc., can be converged to fewer database architectures.

In many client/server infrastructures, centralizing LAN data can bring dramatic improvements in data transfer speed. New enhancements in communications hardware will expand the high-speed connectivity options to server platforms of all types.

There can be two kinds of data integration:

Data integration from several servers and consolidated on a unique repository

Data integration from several repositories in one server and consolidated on a unique repository

Depending on the type of application integration selected, data integration can be performed separately or together with application integration.
