介绍了一种磁盘与光盘融合数据安全存储的新模式,简称磁光阵列或ORAID(Optical Replicated Arrays of Independent Disks)。ORAID模式包括:将数据同时存储到磁盘模块和光盘模块中;可根据数据的属性信息从磁盘模块中读取数据,在目标磁盘无法被读取时,可根据数据在光盘模块中对应的位置信息,将存储有目标数据的光盘中的数据读入预设的数据缓冲区;将存储有目标磁盘数据的光盘中的数据存储到磁盘模块中更换后的新磁盘中。该模式在使用上像基于硬盘的系统一样方便,读写性能与RAID(Redundant Arrays of Independent Disks)一样;在数据安全方面,无论前端硬盘如何损坏数据都不会丢失,并且在硬盘坏损以及重建过程中保持数据的可提供性;ORAID具有物理层面上的合规性,所存的数据不可更改(WORM,Write Once Read Only)并可在无迁移的情况下长期保存50年以上;ORAID无须额外的备份系统。磁光阵列模式同样适用于固态硬盘与光盘的融合。
This paper introduces a new mode of secure storage of data fusion between disk and optical disk, referred to as Optical Replicated Arrays of Independent Disks. The ORAID mode includes: storing data in the disk module and the optical disk module at the same time; reading data from the disk module according to the attribute information of the data; when the target disk can not be read, according to the corresponding position information of the data in the optical disk module , Reading the data in the optical disk storing the target data into a preset data buffer; and storing the data in the optical disk storing the target disk data into the replaced new disk in the disk module. This model is as easy to use as a hard drive-based system and reads and writes the same performance as RAID (Redundant Arrays of Independent Disks); in terms of data security, no matter how the front hard drive corrupts the data, it is not lost, ORAID has physical compliance and data can not be changed (WORM, Write Once Read Only) and can be stored for longer than 50 years without migration ORAID does not require additional Back up the system. Magneto-optical array mode also applies to the solid-state hard disk and CD-ROM fusion.
