150 Tivoli Business Systems Manager Version 2.1: End-to-End Business Impact Management
6.1 Hardware and software prerequisites
This chapter describes the required hardware configuration and prerequisite
software components for the implementation of IBM Tivoli Business Systems
Manager.
We have noted the hardware and software environment used to support the
examples in this book as one possible operational configuration.
6.1.1 Hardware configuration
Basic IBM Tivoli Business Systems Manager implementation requires only two
Intel or compatible computers running Microsoft Windows Server operating
systems, also referred to as wintel servers. This two-server configuration is
adequate for most production environments although a three-server
configuration also can be used. It is always advisable to consult your local IBM
representatives for the optimal configuration.
The two-server basic configuration consists of a server for the SQL database and
another for console and propagation. For the three-server basic configuration,
the console and propagation services run on separate servers.
In additional to the basic configuration, and if it is required, the IBM Tivoli
Business Systems Manager Reporting System would run on the history server.
If Web console service is needed, it should run on its own wintel server. This is
highly recommended because of its demand on the usage of CPU and memory
resources.
Although a Health Monitor System (HMS) is optional, it is advisable to have this
feature enabled and customized to allow the monitoring of IBM Tivoli Business
Systems Manager services. HMS is not very resource-consuming, so it is can
share a machine with the history server. However, it is not recommended to put it
on other IBM Tivoli Business Systems Manager servers.
The total number of servers from this combination makes up the total number of
production system servers.
The other server considerations, besides the production servers, will be the
failover and test and quality assurance (test/QA) servers:
? The Failover System set should be a duplicate of the Production System set.
? Test and QA should be run from two wintel servers. These two servers should
at least match the configuration from the two-server Production System set.
