building the case for system z linux
DESCRIPTION
By: Marianne Eggett, Linux Emerging Technology Practice Mgr, Mainline Information Systems Are you considering a migration to Linux on IBM System z? The first step is to develop a detailed plan that outlines the short term and long term benefits of your migration. In this presentation you will learn: - How to identify the business case to support consolidation with System z Linux - Examples of cost savings other businesses have experienced - How to build a Total Cost of Ownership report specific to your environment To view this presentation with audio, visit: http://go.mainline.com/pages/start/knowledge-center-building-the-case-zlinux-webcast-june-2009/index.html?Campaign_Id=7071&Activity_Id=6131 For other topics, visit: www.mainline.com/kcTRANSCRIPT
Building the Case for System z Linux
Marianne Eggett Linux Emerging Technology Practice Manager
Mainline Information Systems
The Value Statement
• Value of Virtualization• Analyst reports • Customer References• Reliability, Availability, Serviceability (RAS)• Proximity to VSE or zOS data• TCO• Buying once for today and the future
Choosing Applications
• Evaluate server choices – Total Cost of Ownership (TCO) – Correct application availability– Supporting applications– Politics within the organization.– Porting issues
• Shortening end-to-end path length for applications– Collocation of applications– Consolidation of applications from distributed servers– Reduction in network traffic– Simplification of support model
What Makes Good Fit
•DB2 Connect•Oracle•WebSphere Application Server, MQSeries & Portal•WebSphere HATS & HOD•Lotus Domino eMail and Applications•Tivoli TSM Server•DB2 UDB•Communication Controller for Linux (3745 replacement)•Natural migration from VSE•Attachmate•University Classes•Development Environment
Server Consolidation Best Fit
Server Consolidation Best Fit
• CICS® Transaction Gateway • IMS Connect™ for Java™ • Java applications for production and development • Applications requiring top end disaster recovery
model• ComServer and Communications Controller for Linux• LDAP security services • IBI Web Focus
