Network Storage

IPVS network storage based on the Internet for the recent rise of storage ways IP address to access. Simple working principle for IPVS network video storage device: the Internet, on through the terminal equipment IP address, and thus for the terminal equipment visit video and other various information storage. IPVS network video storage using disk array (disk array of Redundant Arrays as RAID: Disks, RAID) simultaneously the way to protect data storage, in traditional NAS storage system provides more reliable based on the data protection, and enhance the equipment visit flexibility. IPVS network storage of data is stored on safety protection, at the same time provide very convenient expansion strategy.

Realization way

SAN Storage Area of Storage Area Network) through a connected to a group of optical fiber channel computer. In this network provides many host links, but not through standard network topology.

SAN focus on specific problems, enterprise-class storage is mainly used for large storage working environment. The current enterprise storage solutions of the problems encountered by two roots are: data and application system generated by combining the structural limits, and currently small computer systems interface (SCSI) standard restrictions. Most analysts think SAN is the future of enterprise-level storage solution, because the SAN facilitate integration, can improve the data availability and network performance, but also can reduce the storage management assignments.

Development trend

A SAN is currently people accepted most potential storage technology solutions and the development trend of future SAN will be open, intelligent and integration. NAS is currently the fastest growing a storage technology, however, the trend of the development of both concerned, in application-layer face SAN and NAS will realize full integration. Can say, NAS and SAN technology has become the mainstream of the current data backup technology, the key lies in how to fully developed on the basis of the all-round, multi-level and data backup system in distributed network environment, through professional data storage management software, combined with the corresponding hardware and storage devices on the network, centralized data backup, thus realize automatic backup, filing, data hierarchical storage and disaster recovery, and other functions.

The application of network storage

The application of network storage network information technology from birth to say the day began, application field along with the development of information technology and continuously increased, but the big classification includes the following four categories:

The ISP's full name is the InternetServiceProvider that Internet service providers;

ICP is Internet Provider by the abbreviations, meaning "Internet Content providers", which provides Internet information search, sorting processing services. Such as sina, sohu, etc.

ASP is the abbreviation of apply Service Provider, meaning "network Application Service providers", mainly for enterprises and institutions in the informatization construction, develop e-commerce based on the Application of Internet provide various services.

The Storage Provider NSPS is a reviatio, meaning "Network Storage service providers", mainly for enterprises, individual provide a Network Storage and transmission, processing service businesses, such as DBank data bank, IDC enterprise.
