What is a NAS head and how does it work in a broadcast environment?
A NAS head is also called a NAS Gateway which is the control function of NAS without the storage device. The storage is connected (typically using Fibre Channel) to a SAN where the resources may be shared by other servers and are managed centrally. The usage is still that of a remote file system where the requesting host redirects file I/O over Ethernet using a protocol such as NFS or CIFS.
