A storage area network (SAN) is a pool of storage systems that are interconnected to the servers in an enterprise. A SAN administrator is the person responsible for administering the various resources that make up the SAN.
A SAN allows the establishment of direct connections between storage devices and servers. It offers simplified storage management, scalability, flexibility, availability, and improved data access, movement, and backup.
A SAN storage system consists of two or four Lenovo Storage V series nodes that are arranged in a clustered system. Clustered Lenovo Storage V5030 systems can support 4 nodes. These nodes appear as part of the SAN fabric. The nodes are connected to the host systems, RAID storage systems, and the storage devices to create the SAN. Other devices, such as fabric switches, might be required to complete the SAN.
A Lenovo Storage V series system with suitable host interface adapters appears as part of the SAN fabric along with the host systems and any other storage systems, all connected together by fabric switches to create the SAN.
