Detailed explanation-1: -What is network-attached storage (NAS)? Network-attached storage (NAS) is dedicated file storage that enables multiple users and heterogeneous client devices to retrieve data from centralized disk capacity. Users on a local area network (LAN) access the shared storage via a standard Ethernet connection.
Detailed explanation-2: -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-3: -Unified SAN. A SAN is noted for its support of block storage, which is typical for enterprise applications. But file, object and other types of storage would traditionally demand a separate storage system, such as network-attached storage (NAS).
Detailed explanation-4: -Through the host adapters the operating system of the server can communicate with the storage devices in the SAN. In Fibre channel deployments, a cable connects to the host adapter through the gigabit interface converter (GBIC).
