Compare storage area networks and network-attached storage. Which is more common in environments where many servers in the same location access the same data?
A SAN is a high-speed interconnection between general-purpose servers and a separate storage server thathandles storage access requests from other servers. NAS uses a dedicated storage server (with its own OS and the hardware attributes of a complete computer) attached to a general-purpose network to handle storage access requests from other servers. Other comparisons include the following:
• A SAN device accepts low-level requests to locations in the storage subsystem's logical address space ("block-oriented access" or "sector-oriented access").An NAS server accepts access requests to files, which can encompass many storage blocks (called "file-oriented access").
• In NAS, a storage server OS manages one or more file systems shared by other servers or clients. In a SAN, a storage server provides a pool of physical storage locations used byother servers to store one or more file systems.
NAS is more common when geographically dispersed servers need access to a common file system. A SAN is more common with many servers in the same location because of its higher performance, andbecause its high-speed interconnections would be prohibitively expensive over longer distances.
