Hardware and software requirements
Before you begin the installation, verify that your hardware and software meet the minimum requirements. For a complete list of system requirements for any particular version, see the System requirements section on Jazz.net Deployment wiki. For a list of IBM Engineering Lifecycle Management (ELM) deployment and sizing guidelines, see Maximizing performance.
Tip: If you plan to configure and administer a high availability environment, make sure that all of the hardware and software components are of the same type and version, such as Linux.
