Problems solved by technology

In short, whether it is planning, design or operation and maintenance, there is a lack of professional and systematic consideration of the entire system data storage management and backup, and it is often blind
[0004] Moreover, because storage devices have not provided mutual protection of data between storage devices, multiple storage device nodes in the storage network system are independent of each other, and failure of any storage device node will cause some data to be unavailable, thereby affecting the entire storage device. Integrity and availability of network systems
In other words, the storage device in the current storage network system is a single node, and the data unavailability caused by the failure of the storage device node will cause the entire storage system to fail

Embodiment Construction

[0035] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0036] In today's global economic integration, information systems have increasingly become the hub and important pillar of social production capabilities. The operation of business processes of enterprises is more and more highly dependent on data, making data an important cornerstone to support the operation of enterprises. These data include not only the data stored in the staff workstations dispersedly, but also the data stored centrally in the disk array. When enterprises bring fast service decision-making and convenient management due to informatization, they must also face the danger of data loss, and large data concentration will also gather risks. This is something people are aware of. The loss of data will interrupt the normal b...

Abstract

The invention discloses a method for implementing storage fault tolerance. The method comprises the following steps of: A1, writing data into first storage equipment, and thus forming a first set of storage; A2, judging whether the writing-in of the data is finished; A3, synchronizing the data from the first storage equipment to second storage equipment, and thus forming a second set of storage; A4, judging whether data synchronization is finished; A5, judging whether any storage has a fault; and A6, automatically switching into a storage path which normally operates. The invention also discloses a device and a system for implementing the storage fault tolerance. A storage network system can tolerate the node failure of single storage equipment, the paralysis of the whole system cannot be caused, and the safety of the data is high.

Description

technical field [0001] The invention relates to the field of computer storage processing, and more specifically, to a method and device for realizing storage fault tolerance. Background technique [0002] Information systems have become a strong support for all walks of life. The security of network data is extremely important. Once important data is damaged or lost, it will have a major impact on the daily production of the enterprise, and even cause irreparable losses. According to the latest survey by 3M, for the marketing department, it takes at least 19 days to restore data and costs $17,000; for the finance department, the process takes at least 21 days and costs $19,000; and for the engineering department, The process would take 42 days and cost $98,000. And during the recovery process, the entire department was effectively paralyzed. Today, a 42-day paralysis is enough to put any company out of business! And the only effective way to minimize the loss is data stor...
