What is Networked Storage Technology 5, what is Networked Storage Technology

Network storage technologies (NAS) is a general networking term based on data storage.

There are three types of networked storage structures: Direct Attached Storage (DAS) and Networked Storage Devices (NAS).

network attached storage) and storage area network (SAN).

DAS: This is a storage device that connects directly to the host system, such as the internal hardware driver of a computer that acts as a server. By far the most commonly used method of data storage in computer systems, DAS is still the most commonly used method of data storage.

DAS stands for Direct Attached Storage. Chinese translates to "direct attached storage". As the name suggests, in this way, the storage device is sent directly to the server via a cable, usually a SCSI interface cable.

IO (Input-Output) requests are sent directly to the storage device. DAS can also be referred to as Server-Attached Storage (SAS). It relies on a server, which itself is a stack of hardware and does not come with any storage operating system.

NAS: Literally a device that is connected to a network and has the function of data storage, so it is also called "network storage". It is a dedicated data storage server.

It is data-centric, completely decouples storage devices from servers, and centralizes data management to free up bandwidth, improve performance, lower total cost of ownership, and protect investment. The cost is much lower than using server storage, but the efficiency is much higher. At present, the world's famous NAS companies include NetAPP, EMC, OUO, etc.

SAN: A high-speed network or subnetwork that provides data transfer between a computer and a storage system. A storage device is one or more disk devices that are used to store computer data.

A SAN network consists of a communication structure responsible for network connectivity, a management layer responsible for organizational connectivity, storage components, and computer systems to ensure the security and strength of data transmission.

Summary. Computing technology mainly refers to the hardware, software, and operating system of computers; Storage technology is mainly aimed at information storage, management, backup and other issues; Network technology mainly refers to the interconnection between computers, including network protocols, communication modes, etc.

Can you add, I don't quite understand it.

Computing technology, storage technology and network technology are the three pillars of computing technology. Computing technology refers to the core technology of a computer, including computer architecture, instruction system, composition, etc.; Storage technology refers to the technology of storing data inside a computer, including internal storage, disks, solid-state drives, etc.; Network technology refers to the technology of data transmission between computers, including local area networks, wide area networks, etc. The relationship between the three is very close, computing technology provides instruction and data processing capabilities, storage technology provides data storage and verification capabilities, and network technology provides data transmission channels and methods.

At the same time, with the continuous development of computer technology, the three technologies are also constantly integrating and developing, further improving computing power, storage capacity and network transmission bandwidth.

Summary. Computing technology refers to the technology of data processing through computers, storage technology refers to the technology of storing data through storage media, and network technology refers to the technology of information transmission and communication through the network.

Computing technology refers to the technology of data processing through the calculation of the dry machine, the storage technology core land tank technology refers to the technology of storing data through the storage medium, and the network technology refers to the technology of information transmission and exchange through the network.

Fellow, I really didn't understand, I can be more specific.

Computing technology, storage technology, and network technology are the three main aspects of modern information technology. Computing technology refers to the hardware and software related technologies of computing blind detection machines, including computer composition principles, operating systems, programming languages, etc.; Storage technology refers to storing data in memory with high access speed, small size, and high group cleaning reliability, and the current mainstream storage technologies include hard disks, solid state drives, etc.; Network technology refers to the technology that realizes the interconnection and data exchange between different devices, including local area network, wide area network, Internet, etc. In short, these three technical aspects have their own focus, but they are combined and mutually supportive, and constitute three important components of information technology.
