A SAN presents storage devices to a host such that the storage appears to be attached locally.
- Improve application availability (e.g., multiple data paths)
- Enhance application performance (e.g., off-load storage functions, segregate networks, etc.)
- Increase storage utilization and effectiveness (e.g., consolidate storage resources, provide tiered storage, etc.), and improve data protection and security.
- SANs also typically play an important role in an organization’s Business Continuity Management (BCM) activities.
