Explanation:
Components of NAS
A NAS device has two key components: NAS head and storage. In some NAS implementations,
the storage could be external to the NAS device and shared with other hosts. The NAS head
includes the following components:
CPU and memory
One or more network interface cards (NICs), which provide connectivity to the client network.
Examples of network protocols supported by NIC include Gigabit Ethernet, Fast Ethernet, ATM,
and Fiber Distributed Data Interface (FDDI) An optimized operating system for managing the NAS
functionality. It translates file level requests into block-storage requests and further converts the
data supplied at the block level to file data NFS, CIFS, and other protocols for file sharing Industrystandard storage protocols and ports to connect and manage physical disk resources The NAS
environment includes clients accessing a NAS device over an IP network using file sharing
protocols.
