Produktbeschreibung

All you need to know about Storage Area Networks

The amount of data of an average company doubles every year. Thus, companies who own 1TB of data today will own 32TB in five years. Storage networks help to tame such data quantities and to manage this data growth efficiently. Since stored data and information are the biggest asset of any company, anyone who is involved in the planning or the operation of IT systems requires a basic knowledge of the principle and the use of storage networks.

Storage Networks Explained covers the fundaments, techniques and functions of storage networks such as disk subsystems, Fibre Channel SAN, Internet SCSI (iSCSI), Fibre Channel over Ethernet (FCoE), Network Attached Storage (NAS), file systems, and storage virtualization. Furthermore the authors describe the use of these techniques and how they are designed to achieve high-availability, flexibility, and scalability of data and applications. Additional attention is given to network backup and the management of storage networks. Written by leading experts in the field, this book on storage area networks is updated and fully revised.

Key features:
Presents the basic concepts of storage networks, such as I/O techniques, disk subsystems, virtualization, NAS and SAN file systems
Covers the design of storage networks which provide flexible, highly-available, and scaleable IT systems
Explains the use of storage networks for data sharing, data protection, and digital archiving
Discusses management of storage networks using SNMP, SMI-S, and IEEE 1244

This book provides system administrators and system architects, as well as students and decision makers, with the tools needed for optimal selection and cost-effective use of storage networks.

The Linux Journal awarded the first edition with the "Editor's Choice Award 2005" in the category "System Administration Book."

Autorenporträt

The authors are employed at IBM's storage competence center in Mainz, Germany. They work at the interface between technology and customers. Their duties cover a wide field of responsibilities. They develop and test new software for storage networks. They present the latest hardware and software products in the field of storage networks to customers and explain their underlying concepts. Last but not least they deploy and support respective hardware and software in customer environments. Ulf Troppens (centre) studied Computer Science at the University of Karlsruhe. Since 1989 he has been primarily involved in the development and administration of Unix systems, storage systems, data and storage networks and distributed applications. Rainer Erkens (left) studied Mathematics at the University of Mainz. His experience in the management of computers and distributed applications goes back to 1992. Since 2005 he is a technical support manager in IBM's European Storage Competence Center. Wolfgang M] uller-Friedt (right) studied Computer Science at the FH Darmstadt. He is a software architect focussing on the software development of management applications for storage networks which support open standards such as SMI-S and IEEE 1244. Nils Haustein (left front) studied Electrical Engineering at the TU Chemnitz. For several years he is with IBM's advanced technical sales support in Europe where he is focussing on digital archiving. Rainer Wolafka (right front) studied Electrical Engineering at the FH Frankfurt and Software Engineering at the Santa Clara University. Since 1997 he is working in the field of storage networks and the software development of management applications for storage networks.
