The book will follow the Storage Technologist EMC course path covering Information Availability Design and Management, planning, implementation, and deployment and will cover components of a storage system and different storage system models--ranging from basic storage models such as Direct Attached Storage (DAS) to networked storage models such as Network Attached Storage (NAS), Storage Area Network (SAN), and Content Addressed Storage (CAS). New content will cover advances in existing technologies and the emergence of "Cloud" which has changed the way computing has been done. Storage consolidation and convergence of networking protocols has given a "unified" approach to data center infrastructure. This edition includes all the updates and information on the new technologies. New content includes: Separate section on emerging area of virtualization and cloud computing New chapter on Cloud Computing Inclusion of new technologies: Data de-duplication, Unified storage, Continuous Data Protection Technology, Virtual Provisioning, FCoE, Flash drives, Storage Tiering, Server Configuration Backup etc. Updates on Concept-in-practice: EMC product examples Enhanced Appendix for additional information
