Need some guidlines for server sizing

server administration XI Server Discussion
1

Hi,
Following is my configuration :
( Two Tomcat servers behind Load balancers, Two BOE/CMS servers in cluster, One DI server & Two Oracle DB repository servers in Veritas Cluster environment)

Two dual core CPUs with 8 GB RAM on each PROD server.
CPU model name : Dual-Core AMD Opteron™ Processor 2218
cpu MHz : 2600.943

Hard drives - Mirrored 146 GB drives.

Memory - 8 GB

I need inputs on the following
@How can we assign services per cpu or per processor
@If the CMS is in cluster shall we consider it as single or double CMS
@Dual core processor means shall we consider as two processors per cpu
@what is the differrence between the cpu support and service support fro users for processing requests

Regards
Badri

Here is some information on the XI R2 Architecture

Each two CPU Tomcat server supports about 95 Concurrent Users and this would be the same for a 4 CPU tomcat as tomcat application is memory bound.

You should always have One CMS per server and two CMS in the Cluster

Hi,

In the sizing recommendation guide provided by Business Objects,
it has been mentioned that,

“1 Dual processor with 2 Web application services” can support 400 simultneous requests.

Please let me know how it is possible to have 2 Web App Services in a Dual Processor system.

You can use Apache Load balancer to multiple Tomcat Web Servers.
