This document provides a methodology for selecting storage virtualization options for IBM Power Systems environments to enable quicker and simpler virtual machine provisioning. It discusses using Shared Storage Pools (SSP) technology with IBM PowerHA and Spectrum Scale. While PowerHA officially supports SSP, there is no official support statement for Spectrum Scale and SSP yet. The document also references articles about mixing SSP and NPIV storage and confirms they can be used on the same virtual machine. It proposes recommendations for using NPIV or SSP based on factors like I/O intensity and replication requirements.
