3.6 Summary

The DS8000 series delivers the first use of the POWER5 processor IBM Virtualization Engine logical partitioning capability. This storage system LPAR technology is designed to enable the creation of two completely separate storage systems, which can run the same or different versions of the licensed internal code. The storage facility images can be used for production, test, or other unique storage environments, and they operate within a single physical enclosure. Each storage facility image can be established to support the specific performance requirements of a different, heterogeneous workload. The DS8000 series robust partitioning implementation helps to isolate and protect the storage facility images. These storage system LPAR capabilities are designed to help simplify systems by maximizing management efficiency, cost effectiveness, and flexibility.
