Before you install WebSphere® Application
Server, verify that your hardware and software meet the minimum requirements.
Hardware requirements
Overall
system requirements will vary based on actual workload requirements.
Use IBM® Systems
Workload Estimator for sizing assistance.
Systems that
do not meet the recommended minimums may 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:
- Minimum server requirements
- Recommended minimum server models:
- WebSphere requires
a partition with a minimum of 600 CPW
- WebSphere applications
can benefit from the addition of an Accelerator Feature on models
where this is available
- Each active WebSphere profile
requires a minimum of 1 GB of memory
- Any partition running WebSphere Application
Server should have a minimum of 2 GB of memory. This memory requirement
is in addition to memory required for any other applications running
on your IBM i server.
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.
- Disk requirements

Server for IBM i disk
