IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Processor requirements
For best performance, processor speeds should be as fast as possible. Choosing faster processors should result in improved response time, greater throughput, and lower CPU utilization. For Windows or Linux on AMD and Intel systems, an x64 processor is recommended.
Multiprocessor systems are generally recommended for the IBM Tivoli Infrastructure components. The infrastructure components (monitoring server, portal server, portal client) run as multithreaded processes and are able to run threads concurrently across multiple processors if they are available. CPU utilization for most components is bursty, and steady-state CPU utilization is expected to be low in most cases. For components supporting large environments, using multiprocessor systems can improve throughput.
When the infrastructure components are installed in a virtualized environment (PowerVM, VMWare, and so on), virtual machines with multiple logical processors are recommended, but dedicated processors are not usually required. Capping the CPU usage of these virtual machines is not generally recommended, so that processing for bursts of activity can utilize spare capacity on the system.
When multiple infrastructure components are installed in a single system or virtual machine, additional processors might be needed for best performance.
For large environments, consider using four or more processors for the Tivoli Data Warehouse database server and the Summarization and Pruning Agent. Although it is not required, the Summarization and Pruning Agent can run on a machine separate from the Tivoli Data Warehouse database server. In this case, ensure that a high-speed network connection exists (100 Mbps or faster) between the Summarization and Pruning Agent and the database server.
