SANs allow applications that move data to perform better, for example, by having the data sent directly from the source to the target device with minimal server intervention. SANs also enable new network architectures where multiple hosts access multiple storage devices connected to the same network. Using a SAN can potentially offer the following benefits:
Availability: A single copy of data is accessible to any and all hosts via multiple paths.
Reliability: Dependable data transportation ensures a low error rate, and an ability to recover from failures is provided.
Scalability: Servers and storage devices may be added independently of one another, and do not depend on proprietary systems.
Performance: Fibre Channel (the standard method for SAN interconnectivity) has a 8GBPS bandwidth and low overhead, and it separates storage and network I/O.
Manageability: Single image of storage media simplifies management.
