• Traffic isolation: All traffic, including multicast and broadcast traffic, is contained within VSAN boundaries. Each device resides in only one VSAN, ensuring absolute separation between user groups.
• Scalability: VSANs are overlaid on top of a single physical SAN. The ability to create several logical VSAN layers increases the scalability of the SAN.
• Per-VSAN fabric services: Each instance of a fabric service within each VSAN runs as a separate thread. Replication of fabric services on a per-VSAN basis provides increased scalability and availability.
• Redundancy: Several VSANs created on the same physical SAN ensure redundancy. If one VSAN fails, redundant protection is provided by a pre-configured backup path between the host and the switch.
• Ease of configuration: Nodes can be added, moved, or changed between VSANs without changing the physical structure of a SAN. Moving a device from one VSAN to another only requires configuration at the port level, not at a physical level.
