Problems solved by technology

[0004] The disadvantage of the prior art is that on the one hand, the system cannot realize space expansion of network storage devices. For example, a single set of low-end network storage devices in the existing market can provide a maximum of 8TB (500GB×16). If the server needs more than 8TB space, the current single system cannot satisfy
On the other hand, each network storage device in the system is independent of each other, so it cannot provide redundant backup

Embodiment Construction

[0035] Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is described in further detail:

[0036] As shown in FIG. 2 , it is a network diagram of a network storage device according to an embodiment of the present invention, and a switch is connected to the network storage system through a network cable. Add an interface on the network storage device, such as SCSI interface or SAS (Serial Attached SCSI, serial connection small computer system interface) interface, connect each network storage device through a connection, such as connecting each network storage device in pairs, Or use other connection methods, such as connecting each non-primary network storage device to the primary network storage device respectively. Among them, SCSI is used for data transmission and is widely used in devices such as hard disks, optical drives or scanners. It is often used as an interface for hard disks and other storage devices.

Abstract

The invention discloses a scalable method of the network storage device, including the following steps: inter-network the network storage device, wherein at least one network storage device is connected with other network storage devices; the network storage devices will elect the main network storage device according to the packet interaction between the network storage devices; the non-main network storage device will back up the configuration information in the elected main network storage device. The invention realizes the redundant backup between the network storage devices and improves the reliability and stability of the network storage devices.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to an expansion method, system and device of a network storage device. Background technique [0002] With the rapid development of computer computing capabilities and network interconnection capabilities, people's demand for networks is no longer satisfied with connectivity capabilities, but more powerful information management capabilities. As more and more key information is converted into digital form and stored in manageable media, the network has created new requirements for the ability to store and manage information, so network storage devices are widely used, and network storage devices are a A technology that integrates distributed and independent data into a large, centrally managed data center for easy access to different hosts and application servers, including storage devices (such as disk arrays, CD / DVD drives, tape drives, or removable storage m...
