A reliable, scalable, resilient server infrastructure is critical for a Siebel eBusiness Applications deployment to succeed. Low overall cost of this infrastructure can be a major contributing factor in achieving ROI in the shortest amount of time. IBM provides servers for Siebel solutions that are low cost and at the same time among the most reliable and scalable servers on the market.
Choose to Scale Up or Scale Out
The choice of servers and the technology in those servers gives you the choice to have your infrastructure scale up or scale out. Infrastructures that scale out rely on many smaller servers and adding capacity usually means adding additional servers. Scaling up relies are using a small number of larger servers. Server virtualization is often critical to these infrastructures to make the best use of available resources. Adding capacity involves adding additional processors and memory to existing systems and this must be done with as little disruption as possible.
Siebel Systems architecture is suited for both scale out or scale up with a few exceptions. Database servers must be implemented on a single system so the choice of that server should be made with future growth in mind. Most of the other Siebel servers work well in both environments so vendors like IBM, HP, Sun offer the choice of many smaller servers or a few larger ones.
A wealth of performance knowledge
The sizing shown in this document is based on a deep understanding of how Siebel eBusiness Applications perform on server systems.
IBM was the first to publish benchmark results under Siebel System’s Platform Sizing and Performance Program (PSPP). IBM published three sets of results before any other vendor made their results public.
Understanding that benchmarks give only limited insight into the performance of an overall solution. IBM has worked with its customers, integration partners, our internal implementation team, Siebel System’s internal implementation team, the IBM-Siebel International Competency Center, Siebel development and Siebel Expert Services to document and incorporate the characteristics of over 200 benchmarks, performance studies and customer implementations into IBM’s tools for sizing Siebel eBusiness Applications. Siebel Systems has even adopted IBM’s sizing methodology for its own use.
Collaboration that adds value and reduces risk
The collaboration between IBM and Siebel make our joint solution stronger. Siebel Systems does the first deployment of each new release, its own implementation, on IBM eServer Systems. IBM is in the middle of one of the largest rollouts of Siebel eBusiness Applications with over 100,000 users planned to go online by early 2005.
IBM maintains onsite development resources at Siebel Systems headquarters in San Mateo, CA. These people work side-by-side with Siebel architects, developers and performance engineers throughout each release. They are involved from design through general availability to confirm that every advantage is leveraged and the performance and scalability of the entire solution is well understood
