This book covers the fundamentals of storage networks by showing how these technologies can best work together to meet current business requirements. The accessible chapters of the first edition of the book have been thoroughly updated.The book is divided into two parts. The first part explores foundation technologies for storage networks by considering intelligent disk subsystems, the second part of the book presents the applications that exploit the new infrastructure of storage networks Presents the fundamental technologies for storage networks and shows how these technologies help to meet current business requirements. Updates many of the aspects of the first edition, including new chapters on data archiving and business continuity. Covers fibre channel SAN (Storage Area Networks), Network Attached Storage, iSCSI (network protocol standard), DAFS (Direct Access File System) and InfiniBand technologies. Explains applications such as data mirroring, network backup, monitoring of storage networks, management of removable media and many more. Written by very experienced professionals who tailored the book specifically to meet customer needs.

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.
