Network-based storage (NAS) is a network attached storage (NAS) computer data storage device attached to a network so that users can access data from many other computers over the network. NAS devices are designed for sharing information between multiple users in the same network. NAS devices are especially useful in large, complex networks. The primary role of NAS devices is to store data in a data center and deliver it to computers on the network for processing, archiving, and sharing.
NAS devices are configured by connecting a NAS client to the NAS server and then assigning network storage partitions (NAS partitions). NAS partitions include the operating system, user profile, programs, and application settings.
NAS devices can either be hard-wired or have a built-in network card. The hard-wired devices require less maintenance because they can usually be disabled by the administrator and reconfigured easily. The built-in network card requires much more maintenance but usually provides better reliability and performance. Hard-wired devices can usually be configured by installing the driver on the computer where the NAS device will be used and by replacing the existing network adapter.
Some of the advantages of NAS include the ability to perform a number of tasks at the same time, faster network speed, fewer interruptions, and less storage space requirements. One disadvantage of NAS is that the network has to be large enough for the number of users to be supported. In small networks, NAS may be impractical and may not provide enough space for data storage and backup.
NAS systems come with various software packages which include features such as web-based administration, data backup, management, and security. Some of the most popular NAS packages include DataNumen, CPanel, Xtreme IT, QuickBooks, DataNumen Lite, and My-NAS.
NAS hardware includes hubs, racks, servers, cabinets, enclosures, and storage devices. A NAS hub contains a single network connection, while a rack holds several NAS devices. The rack is the most common type of NAS system, as it saves space and allows the administrator to place more NAS devices on the same floor space.
NAS cabinets can be used to mount and store NAS devices while leaving free space around them. The storage devices can be mounted on the cabinets, either vertically or horizontally.
NAS system racks can have additional storage shelves as well as shelves for expanding and storing larger NAS devices. Most NAS system racks also contain racks for servers or redundant power supplies. Most NAS systems use cabling that connects the network cables to each storage unit.
NAS enclosures are similar to traditional computer racks but in a smaller form. They are similar to a cabinet without all the shelves. NAS enclosures can be used for data storage and for NAS devices such as printers, scanners, and network switches. They can also be used to mount network cameras and other devices.
Storage units consist of either hard-wired or built-in network devices. Hard-wired devices are commonly used for storing data that requires more than one physical network cable. Built-in network devices provide easy access to a specific IP address. Some hard-wired devices can be reconfigured and customized to suit an individual user's need.
Storage space for NAS systems is available in both traditional and portable formats. Portable devices include USB drives, CD ROM drives, external drives, and SAN (storage area network) adapters. Other devices include NAS tape drives, optical drives, and NAS drives.
Some of the benefits of using a NAS are its ease of management, flexibility and easy configuration. A user can install applications, configure and monitor the system, and create backup files. The system can be customized to meet a company's particular needs.
With the advent of NAS technology, organizations can enjoy increased efficiency, greater storage space, and the opportunity to have more control over network traffic. With a NAS system, data can be stored on servers that are in the office or offsite and that can run applications or data on-site or off-site.
