Network Attached Storage

From Computing and Software Wiki

This is an example application for a Network Attached Storage (NAS) Device. Note that the data on the fileserver is available to a select portion of the internal network, but is protected from the outside world by a firewall.

Network Attached Storage (NAS) provides a network connected central location for data storage, as opposed to distributing data storage responsibilities among the various clients of the network.

History

Data has always been stored locally on workstations and personal computers because slow network speeds made remote data inconvenient to access. Recent improvements to data transfer speeds and the proliferation of broadband connections have allowed for the centralized storage of data for an entire internal network. Network Attached Storage came into existence as a computing device with large capacity non-volatile storage connected to the network using the Internet Protocol (IP). It provided a storage location for large files that were cumbersome to store and process on Personal Computers in both workplace and residential applications. Data transfer speeds for early NAS devices depended heavily on the CPU and RAM speeds of the internal computer. However, in recent years many NAS devices have adopted the iSCSI network protocol for data transfer, greatly reducing the processing and memory needed for common tasks.
