IBM Midrange System Storage Hardware Guide

Новый Redbook посвященный системам хранения данных производства IBM. Рассматриваются как новые, так и снятые с производства модели класса Midrange. Несмотря на статус Draft, Rebook содержит много полезной информации.

This IBM Redbooks publication consolidates, in one document, detailed descriptions of the hardware configurations and options offered as part of the IBM Midrange System Storage servers which include the DS4000 and the DS5000 family of products.

This edition covers updates and additional functions available with the IBM System Storage DS Storage Manager Version 10.60 (firmware level 7.60).This book presents the concepts and functions used in planning and managing the storage servers. Concepts such as multipathing and path failover are discussed. The book offers a step-by-step guide to using the Storage Manager to create arrays, logical drives, and other basic (as well as advanced) management tasks.

This publication also contains practical information about diagnostics and troubleshooting, and includes practical examples of how to use scripts and the command-line interface.

This publication is intended for customers, IBM Business Partners, and IBM technical professionals who want to learn more about the capabilities and advanced functions of the DS4000 series of storage servers with Storage Manager Software 10.60. It also targets those who have a DS4000 and DS5000 storage system and need detailed advice about how to configure it.

This Redbook is designed specifically to address the Hardware features and configuration of the IBM Midrange System Storage servers and can be used in conjunction with the other IBM Midrange System Storage Redbooks listed below:
