Virtualization environments
In a virtualization environment, such as...
- IBM PowerVM VIOS
- IBM z/VM
- IBM PR/SM
- VMware ESX/ESXi
...part of the system capacity will be used by the virtualization software to manage and service resource requests. The hardware requirements listed on this page are the minimum necessary requirements for WebSphere Commerce to run, after all virtualization demands are taken into account, including disk space and processor demands.
Partitioning of hardware into multiple virtual servers can have a dramatic affect on performance. Application Servers in particular can be very sensitive to processor caching and overall memory constraints, and software virtualization resource availability can be unpredictable. Depending on the virtualization configuration, the overhead of operating in virtualized environment could be as much as 30% or more of the overall available hardware capacity.
If you are planning to deploy a virtualized environment, ensure that stress testing is a part of the project plan.
