The storage networking is a dedicated, high-speed network established to directly connect storage peripherals. It allows the direct communication between the storage devices and the client machines on the network. It provides a efficient solution for historical view of server attached storage. The emergence of storage networking brings a new trend in today’s networking technology. The two-major components of storage networking are SAN and NAS.
SAN is a storage area network. This is a high performance network deployed between the servers and storage devices. Typically SAN uses the fibre channel technology. It provides the various advance facilities over the LAN and WAN.
NAS is a network-attached storage. It is a storage element, which is directly connected to network to provide file access to the servers. NAS is generally used on TCP/IP networks. NAS devices are mainly used for security purposes.
