Problems solved by technology

If a hard disk fails, it may cause the failure of the entire storage device
And if the hard disk failure is serious, then the relevant data will be lost forever and cannot be recovered.
Second, it is impossible to achieve load balancing among multiple physical hard disks

Embodiment

[0027] A method for JBOD mass storage data security described in this embodiment, first realizes JBOD information security by constructing RAID, RAID allows the operating system to store data and read data in the hard disk at the same time; secondly, optimize the security performance of JBOD through virtualization equipment, and store a virtualization equipment between the server operating system and the JBOD equipment. The verification field is written in the hard disk at the same time; when a certain hard disk fails, the data in the failed hard disk can be restored by virtue of the verification field.

[0028] In the JBOD mass storage data security method described in this embodiment, the step of JBOD information security is realized by constructing RAID. RAID can allow the operating system to store data and read data in the hard disk at the same time, which can greatly improve the security of the hard disk. Storage efficiency: After adopting RAID, data between hard disks wi...

Abstract

The invention discloses a method for guaranteeing security of JBOD mass memory data, and relates to the field of memory and security. The method comprises the steps that JBOD information security is realized by constructing an RAID, and the RAID enables an operating system to store data into and read data from a hard disk; an RAID system can recover data automatically according to verification fields on other hard disks; a virtual device is arranged between the server operating system and a JBOD device, when certain hard disk has a fault, the data in the failed hard disk is recovered by the aid of the verification fields, and the security performance of the JBOD is optimized through the virtual device. JBOD information security is realized through construction of the software RAID, the hard disk storage efficiency can be increased greatly without data losing; further, the security performance of the JBOD is optimized through the virtual device, the storage performance can be improved, and the data security can be improved.

Description

technical field [0001] The invention relates to the field of storage and security, in particular to a JBOD mass storage data security method. Background technique [0002] According to statistics, the annual growth rate of the amount of stored data reaches 50%~60%. In the face of new applications and increasing storage capacity, storage is facing three major challenges: first, the cost of storing data is constantly increasing; second, data storage Explosive growth in capacity; third, the increasingly complex environment makes the stored data unmanageable. JBOD is a storage solution proposed in recent years and widely used. When storing data, the data is simply stored from the first hard disk. When the storage space of the first hard disk is used up, store data in the following hard disks. JBOD can be used in direct-attached storage based on parallel SCSI cables, or in storage networks with Fiber Channel (Fibre Channel) interfaces. The configuration is very simple, you on...
