Define network attached storage (NAS) and compare it to a storage area network (SAN).

What will be an ideal response?


NAS is essentially a dedicated file server that has its own file system and typically uses hardware and software designed for serving and storing files. While a SAN shares a fast, low-level interface that the OS can treat just like it was a disk, the NAS-because it has its own internal file system-has to perform filesystem work for all of its clients. While the simplicity and low price of a NAS make it attractive for some uses, these performance issues limit its utility in high-performance virtualization clusters.
