1 Chart -2 GSE, June 20th, 2003 Gerard Laumay Architect IBM EMEA Products and Solutions Support Center Montpellier, France Copyright IBM Corporation 2000, All rights reserved. Date of last update: August 6, 2002 Server Consolidation with on Traditional Server Farm Server farm in a box Discrete s consume incremental expense Hardware price and maintenance Floor space, power, cooling Additional support staff Per image software fees Connectivity requires kilometres of cables High availability ensured by spares / re-boots Disaster recovery rarely successfully tested Reduce costs without sacrificing autonomy (one per application) Virtual, high-speed, inter- connectivity Exploit an architecture designed for High Availability Mainframe qualities of service Proven disaster recovery services Connect to discrete s as required

2 Chart 3-4 Virtualization of Servers Reasons for farms Unix paradigm: one application per Additional failover s for high availability Separate s for development, test and production Most farms have low average utilization Typically 0%-5% for UNIX s, Typically 5-0% for Windows s and zseries allows to virtualize s Still separated virtual systems Hardware can be shared between systems Whitespaces can be saved Fast setup of new s by reusing already available hardware Typical Server Utilisation Intranet Servers (Web Applications) Server Utilization Intranet Web Large German Banking Institute Utilized Processors :00 02:00 04:00 06:00 08:00 0:00 2:00 4:00 6:00 8:00 20:00 22:00

Availability of 7 tier chain is 0,98^7 = 0,87 98% means week per year downtime 87% means /2 months per year downtime for the solution Don't forget the network between all the s!! 2 Web 5 Application 6 Internet Firewall 3 DNS Firewall 2 4 Database Intranet 7
