The use of external storage and the benefits of virtualization have become a topic of discussion in the IBM i environment during the last several years. The question tends to be, what are the advantages of using external storage attached to an IBM i environment, as opposed to using internal storage. The use of IBM PowerVM virtualization technology to virtualize Power server processors and memory has also become common in IBM i environments. On the other hand, virtualized access to external storage and network resources using a VIO server is still not widely used.
This IBM Redbooks publication gives a broad overview of the IBM Storwize family products and their features and functions. It describes the setup required on the storage side and describes and positions the different options for attaching IBM Storwize family products to an IBM i environment. Basic setup and configuration of a VIO server specifically for the needs of an IBM i environment is also discussed.
In addition, different configuration options for a combined setup of PowerHA System Mirror for IBM i and the Storwize family products are described and positioned against each other. Detailed examples are provided for the setup process required for these environments.
The information that is provided in this book is useful for clients, IBM Business Partners, and IBM service professionals who need to understand how to configure their IBM i environment with attachment to the Storwize family products.
