Embodiment Construction

[0037] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the following in conjunction with the appended Figure 1~2 And embodiments, the RAID-based security early warning system and method of the present invention are further described in detail. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] The core of the RIAD-based safety warning system and method of the present invention is to collect relevant health information on the RAID system, including the health information of the disks in the disk array, the array status, ambient temperature and fan speed in the array; CPU temperature, fan speed, and simulated disk failure, array failure, and storage system operating environment to obtain simulated system health information, and analyze the collected health information. Through the analysis, potential pro...

Abstract

The invention discloses a security early warning system and a method based on RAID, which belong to the field of computer system structure storage. The system comprises a fault decision unit, a fault detection unit and a fault simulation unit, wherein the fault decision unit is responsible for collecting the health information of a storage system in real time, and can send early warning information according to the preset health threshold value or other early warning strategies, the fault detection unit detects the operation state of a disc, detects the operation state of the disc array, and detects the sate of the operation environment, and the fault simulation unit is used for disc fault simulation, disc array fault simulation and external environment simulation, and can trigger the fault decision unit for implementing the early warning. The invention also provides a security early warning method based on RAID, and the security early warning is carried out on the storage system by using the system. The system and the method can be used for giving early warning on the fault of the RAID in advance, and users can adopt optimal maintenance management to ensure the data security and the system health.

Description

technical field [0001] The invention belongs to the field of computer system structure storage, in particular to a RAID-based safety early warning system and method. Background technique [0002] RAID is the abbreviation of "Redundant Array of Independent Disk", which means independent redundant disk array in Chinese. Redundant disk array technology was born in 1987, proposed by the University of California, Berkeley. Simply explained, it is to combine N disks into a virtual single large-capacity disk through the RAID controller. The adoption of RAID brings great benefits to the storage system, among which improving the transmission rate and providing fault tolerance are the biggest advantages. [0003] Traditional storage systems use redundancy technology to ensure data reliability. When data damage occurs in the storage system, data is repaired by means of data reconstruction or data recovery. This method has a long time window for data maintenance, and in data maintenan...
