NAS products have been widely used in educational research, ISP/ASP, IDC, Web/E-mail server clusters, finance/insurance, telecommunications, CAD, medical systems, printing, network audio and video VOD on demand and many other fields.
In foreign countries, NAS devices have become the preferred device for network data storage and are increasing at an annual rate of 66.5%. NAS products have been widely used in educational research, ISP/ASP, IDC, Web/E-mail server clusters, finance/insurance, telecommunications, CAD, medical systems, printing, network audio and video VOD on demand and many other fields. In China, more and more companies have realized that data security will become the lifeblood of various industries. From the rapid development of our country in recent years, it can be foreseen that NAS storage will penetrate into various industries at a faster rate than in foreign countries.
NAS (Network Attached Storage)
NAS, the English full name NetworkAttachedStorage, can be translated into network attached storage, is a dedicated data storage server. It is data-centric and completely separates storage devices from servers and centrally manages data to free up bandwidth, improve performance, reduce total cost of ownership, and protect investments. The cost is much lower than using server storage, but the efficiency is much higher than the latter. NAS can meet the needs of SMEs who want to reduce storage costs but cannot afford the high price of the SAN. It has a fairly good performance-to-price ratio.
Which industries can use NAS equipment? First of all, look at whether the core business of this unit is based on an information system. The security of the data is very demanding. Secondly, look at whether the information system already has or will have a huge amount of data that needs to be preserved, and the degree of data management. The requirements are higher; in the end, it is also possible to determine whether there are heterogeneous platforms in the network, or whether they will be used later. If the answer to the above question is yes, then it is necessary to focus on using NAS devices.
Application of Network Attached Storage in the Security Industry With the rapid development of computer network technology, video surveillance systems are currently in digital video surveillance systems represented by DVR digital hard disk recorders, and are fully equipped with NVS servers, network video servers, and IP Camera network cameras. The recently emerged NVR network video recorder represents the transition phase of the network video surveillance system represented. In this transitional phase, the vast majority of applications are digital and network hybrid systems. NetworkDVR network digital video recorders are among them.
Compared with digital video surveillance, IP video-based network video surveillance systems can build a larger, more complex, more flexible, and more scalable application system, the core part of which is a set of widely compatible and The highly integrated intelligent video surveillance management software connects the monitoring system with the computer network/information management system and enables two independent systems to converge to realize true triple play (data, voice and video images).
A complete set of intelligent video surveillance management software can be applied to the centralized monitoring and management of unlimited number of digital video image equipment, access control systems, professional alarm panels, and environmental monitoring equipment in large and medium-sized IP network video surveillance environments. Computer information management systems such as geographic information systems are tightly integrated. Since network video surveillance is a network-based audio and video streaming transmission, the performance of video surveillance management servers will be greatly affected in the case of a large number of audio and video streaming. The more data, the scheduling of I/O operations by the video surveillance management server. The more complicated the management of the cache is, the frequent access to the storage device requires a large amount of resources, which affects its processing capabilities.
