## Storage area network 

## 2 

The storage area network (SAN) is one of the most important aspects when implementing and configuring IBM Spectrum Virtualize and IBM FlashSystem. 

This chapter does not describe how to design and build a flawless SAN from the beginning. Rather, it provides guidance to connect IBM Spectrum Virtualize and Storwize in an existing SAN to achieve a stable, redundant, resilient, scalable, and performance-likely environment. However, you can take the principles here into account when building your SAN. 

Important, IBM FlashSystem 9200:  On 11th February 2020 IBM announced the arrival of the IBM FlashSystem 9200 to the family. This book was written specifically for IBM FlashSystem 9100, however most of the general principles will apply to the IBM FlashSystem 9200. 

If you are in any doubt as to their applicability to the FlashSystem 9200 then you should work with your local IBM representative. 

This book will be updated to include FlashSystem 9200 in due course. 

The Flashsystem 9200 product guide is available at:
