Preface

Introduction

The IBM® b-type Gen 8 Fibre Channel directors and switches provide a resilient, scalable, and secure foundation for modern data centers, supporting virtualization, hybrid cloud, and next-generation Non-Volatile Memory Express (NVMe) and flash storage workloads. This IBM Redbooks® publication helps administrators design, implement, and migrate to an IBM b-type Gen 8 storage area network (SAN). It provides an overview of key hardware and software components and explains how to install, monitor, optimize, and troubleshoot SAN environments. By using this book, you can learn best practices for SAN design, along with techniques for managing, monitoring, and maintaining a high-performance storage infrastructure.
