AS/400 Disk Storage Topics and Tools

Uncover the basics of AS/400 disk storage. This redbook is designed to help AS/400 system administrators and operators gain a broad understanding of AS/400 disk storage, architecture, and management. The technology covered in this redbook is based on current AS/400 system offerings, along with pertinent history, in contrast to newer technology and methods.

This book is divided into two parts. Part 1 discusses hardware architecture and components, while Part 2 discusses tools to manage disk storage. You’ll gain a base understanding of AS/400 system architecture and learn about the architecture of disk storage, disk storage components, and disk storage options. You’ll also learn about the storage features that are available to maximize the availability and performance of the disk subsystem.

Plus, this redbook offers information on tools and tips to help the AS/400 system administrator and operator to better manage the AS/400 disk storage subsystem space utilization, both historically and in real-time. Management tips are based primarily on the software components offered with OS/400 V4R4.

Throughout this redbook, the term direct address storage drive (DASD) is used. For the AS/400 system, DASD is another term for disk storage. We use these two terms interchangeably.
