SAN (Storage Area Network)
A SAN consists of two tiers: The first tier — the storage plumbing tier — provides connectivity between nodes in a network and transports device-oriented commands and status. At least one storage node must be connected to this network. The second tier — the software tier — uses software to provide value-added services that operate over the first tier.
