Detailed explanation-1: -A Storage Area Network (SAN) is a dedicated, independent high-speed network that interconnects and delivers shared pools of storage devices to multiple servers. Each server can access shared storage as if it were a drive directly attached to the server.
Detailed explanation-2: -Examples include a disk drive device that backs up its data to a tape device without server intervention or a remote device mirroring across the SAN.
Detailed explanation-3: -Both SAN and network-attached storage (NAS) are methods of managing storage centrally and sharing that storage with multiple hosts (servers). However, NAS is Ethernet-based, while SAN can use Ethernet and Fibre Channel.
Detailed explanation-4: -A Storage Area Network (SAN) is a specialized, high-speed network that provides network access to storage devices. SANs are typically composed of hosts, switches, storage elements, and storage devices that are interconnected using a variety of technologies, topologies, and protocols. SANs may span multiple sites.
Detailed explanation-5: -ISCSI, FCoE, FCP, and Fc-NVMe are the protocols used in SAN. 9.
