Storage Area Networks

This tutorial compares Storage area Network (SAN) technology with previous storage management solutions with particular attention to promised benefits of scalability, interoperability, and high-speed LAN-free backups. The paper provides an overview of what SANs are, why invest in them, and how SANs can be managed. The paper also discusses a primary management concern, the interoperability of vendor-specific SAN solutions. Bluefin, a storage management interface and interoperability solution is also explained. The paper concludes with discussion of SAN-related trends and implications for practice and research
