Duration: 5 Days Overview: This five-day course provides a comprehensive and accelerated understanding of SAN technologies and concepts. Students will gain the experience needed to tackle the challenges of working in enterprise class SAN environments. Target Audience: This course is designed for technical professionals seeking an accelerated learning path that includes both conceptual knowledge of Fibre Channel SAN technologies and experience in heterogeneous SAN environments. Pre-requisites: Participants will be expected to have the following experience: Basic technical understanding of networking and storage, concepts and terminology. Experience managing Windows or UNIX systems. Recommended free web-based training: SAN Fundamentals (U5527aae) Key Participant Benefits: This course provides a comprehensive understanding of the leading SAN technologies and the experience needed to tackle the challenges of working with SAN solutions. At Course Completion: This practical five-day course provides comprehensive exposure to SAN solutions and supporting technologies, such as Fibre Channel and IP storage. Participants learn about protocols, standards, management practices and tools, and SAN design and implementation considerations. Class discussions cover a wide range of topics, including the capabilities and limitations of the various supporting technologies and SAN management in enterprise environments. Each lab provides experience with component configuration, SAN management, and other SAN related activities. Outline: Expand All Introduction What is a SAN? / Why a SAN?
