 LPAR Security on POWER5 Processor-based Systems
Securing a system is a trade off between flexibility and security. The IBM POWER5 systems core function provides a robust platform with strong hypervisor controls on the separation of partitions from one another. The optional components of the POWER5 systems provide additional functionality and flexibility to virtualize devices, dynamically move resources. Each of these functions affects the security posture of the system. |
