If you want to use image mode  volumes, decide whether and how you plan to migrate them into managed mode  volumes. – Information on the back-end storage that exists in the environment and is intended to  be virtualized by the Storwize V7000. GLYPH<SM590000> Decide whether you are going to use Storwize V7000 to virtualize external storage. If you  do, collect and document the following items: GLYPH<SM590000> Collect and document the number of hosts (application servers) to attach to the Storwize  V7000. Identify the traffic profile activity (read or write, sequential, or random), and the  performance requirements (bandwidth and input/output [I/O] operations per second  [IOPS]) for each host.

Always verify any statements that are made in this book with the  IBM Storwize V7000 supported hardware list, device driver, firmware, and recommended  software levels information that are available at the following websites: To maximize the benefit that is realized from the Storwize V7000, pre-installation planning  must include several important steps. These steps ensure that the Storwize V7000 provides  the best possible performance, reliability, and ease of management for your application  needs. The correct configuration also helps minimize downtime by avoiding changes to the  Storwize V7000 and the storage area network (SAN) environment to meet future growth  needs. This book is  not  intended to provide in-depth information about the described topics. For an  enhanced analysis of advanced topics, see  IBM System Storage SAN Volume Controller and  Storwize V7000 Best Practices and Performance Guidelines , SG24-7521. The general rule of planning is to define your goals, and then, plan a solution that can be  shown to meet these goals. Always remember to verify that each element of your  configuration is supported. Consider the following points when planning for the Storwize V7000: 44  Implementing the IBM Storwize V7000 with IBM Spectrum Virtualize V8.2.1
