Computer Networks : Types and Topologies
Welcome to “Computer Networks: Network Storage Types.” After watching this video, you will be able to: Explain what a SAN does. Explain what a NAS does. List the differences between NAS and SAN.
A Network Attached Storage, or NAS, device is a local file server. It acts as a hard drive for all devices on a local network. NAS devices provide: Convenient sharing across network devices. Better performance through RAID configuration, remote access, and they work when the Internet is down. A NAS is a connected storage device that is local to the network it serves. A SAN is a storage system that involves many devices and connections across multiple sites.
NAS and SAN are different because NAS is local to its network while a SAN is a storage system that spans multiple offsite locations and involves many devices, servers, and connections.
