NAS: A data-centric data storage mode (Akoma Tiandi Digital Technology Co., Ltd. May 30, 2001) has brought huge power to the development of the world. Progress in technology makes people need effective resources from various places. The development of the network era, plus colorful multimedia applications, making the data data running on different system platforms in geometric levels. IDC predicts that the capacity of disk storage systems in the next few years will increase at 79.6% per year. By 2003, the overall storage capacity will approach 200,000 TB. Gilder pointed out that the capacity requirements of various storage devices exceeded 60% per year, and each step of computer performance was only increased by 33%. At the same time, the development speed of storage devices was three times behind network bandwidth. . Traditional server-centric storage network architecture faces the source of the source of streams that is not strong. It is desirable to find a new data storage mode, independent storage device, with good scalability, availability, reliability to meet future data storage requirements. The development of the data storage market enables the server-centric data storage mode to conversion to data-centric data storage mode. NAS is the specific embodiment of this new type of data storage mode.
Typical Lan Using NAS
NAS, English is called NetWork Attached Storage, which can be used for network attach storage. It is defined as a special dedicated data storage server, inline system software, can provide cross-platform file sharing features. NAS devices are completely data-centered, completely separated storage devices and servers, centrally manage data, thereby effectively releasing bandwidth, greatly improving network overall performance, or effectively reducing total cost of ownership and protecting user investment. In just a few years, NAS devices have gradually become the preferred key devices for network data storage. The IDC predictive report pointed out that the NAS equipment's income will increase at a rate of 66.5% per year, and it will be close to $ 7 billion in 2003. According to NAS's development, the Gartner Group has grown from US $ 1 billion in 1999 to more than 10 billion dollars in 2003. More and more people have begun to pay attention to NAS equipment and their basic network data storage solutions. More and more companies are also stepped in studying NAS products, US PROCM, NETAPP, EMC and other companies have gradually become medium and high-end NAS products. Spokesperson. NAS products apply mature network technology, which has been widely used in education research, ISP / ASP, IDC, Web / E-mail server cluster, financial / insurance, telecommunications, CAD, medical system, printing, online audio and video vod on demand, etc. .

With the popularity of high-speed internet access, the emergence of high-speed Internet access, generally in-depth multimedia and information are greatly enriched, and storage capacity increases with speeds each year. [1] This problem is no longer only proprietary. In the middle, small-scale business is now facing how to increase and manage expansion storage requirements, which has developed to the extent of increasing strategic issues in emergence. In fact, studies have shown that many customers are now used by most of their IT budgets, which greatly exceeds the servers used for servers.

Features The value of the NAS server is that you give the least investment to solve your needs for storage, you will be able to increase the storage space you need in a short period of time, anywhere to increase the storage space you need. This is obvious by comparing the cost of using the server to store every billion bytes (GB). Typical costs for a medium-scale product spending approximately $ 70, while NAS costs only need every billion words. Section GB $ 20 Meishi, compare If you choose NAS Server you will get the same performance and application services with less investment. On the other hand, all NAS servers are used by the concept of device software licenses, without soft, hardware License restrictions, and differently than customer licenses used by the application server. This significantly reduces the need for recursive growth of software investment due to the expansion of the company. This means that it will alleviate investment costs in software when they grow. Additional features include: independent of the operational platform, different class file sharing, cross-protocol user security / licenses, the operation / management of the browser interface, and does not interrupt the network's increase and removal server. The prospect of NAS is shown in accordance with the Idc authority research report, NAS will continue to grow in the Windows, Linux, and UNIX platforms in the next five years. [3] as shown below.
