NAS, also known as NAS storage, is the acronym of English NetworkAttachedStorage, translated to network attached storage, simply connected to the network, with data storage device, so also known as the network memory, it can be directly connected to a computer network, the heterogeneous network users provide centralized data access. It can be connected directly to a computer network and provides centralized data access to heterogeneous network users.
NAS network storage is a dedicated data storage server, which is data-centric, completely separate the storage device from the server, centralized management of data, thus freeing up bandwidth, improving performance, reducing total cost of ownership, and protecting the investment, due to the fact that its cost is much lower than using server storage, while the efficiency is instead a little more efficient, so it's widely used in office automation, taxation, advertising design, Campus network, medical data storage and other fields.
Two, NAS has what function
NAS is relatively powerful, for most users, the basic function of NAS is to act as a network memory, can store text, video, audio and other forms of data, and with NAS network memory can be deleted, compression of duplicate data in order to optimize the storage space, effective savings of 80% of the storage space, hard disk protection. Hard disk protection, in addition to the network memory function, NAS storage features are:
1, file **** enjoy the function
In the "Online Neighborhood" to find the NAS network storage device, and in its **** enjoy the directory to store public documents, usually through the browser to access and You can access and manage the files in the NAS through a browser to realize file ****enjoyment.
2. Backup Function
General NAS has various backup functions, including local backup (backing up data on computers to NAS via LAN), off-site backup (backing up data on computers in off-site locations to NAS via WAN), and inter-NAS backup (copying data from NAS to NAS), so you don't need to be afraid of losing data, and the backup operation is very convenient. It is very convenient.
3, network printing
The ordinary printer will be connected to the NAS through the USB interface, open the network printer function of the NAS network storage, we can use this printer in the LAN **** with.
4, photo *** enjoy function
Store photos and videos in the designated directory of the NAS network memory, you can log in to the NAS Web site through the browser to watch, very convenient.
Three, NAS can be a server
Yes.
NAS is a special kind of dedicated data storage server, in fact, a storage device with a thin server (ThinServer), its role is similar to a dedicated file server, but it is different from the traditional general-purpose servers, it does not have a general-purpose server most of the computing functions, but only to provide the file system function for storage services, so the server requirements are reduced, which can greatly reduce server costs.
