IBM i prerequisites
Before you install WebSphere® Application Server, verify that your hardware and software meet the minimum requirements.
Hardware requirements
Overall system requirements vary based on actual workload requirements. Use IBM® Systems Workload Estimator for sizing assistance.
Systems that do not meet the recommended minimums might be used in environments that support a
limited number of users and where longer server initialization times are acceptable. The recommended
hardware minimum requirements follow:
These requirements are based on a single WebSphere Application Server profile. Additional profiles running concurrently require additional resources.
These requirements represent the recommended minimum requirements. Deployments that must support many users or require shorter response times might require additional resources.
