摘要:
A method and system of method and system of enhanced RAID level 3 is disclosed. In one embodiment, a method includes allocating three times a physical storage capacity of a data drive to a dedicated parity drive of a ‘n’ physical drives of a redundant array of independent disks, recovering n−1 physical drive failures of the ‘n’ physical drives through a parity-in-parity technique in which certain number of parities generated during an initial write of data may be physically stored and using an XOR function applied to the stored parities to recreate un-stored parities which enable recovery of the n−1 physical drive failures. The method may include creating a superior read/write access capability and/or a superior parity data redundancy through the mirroring. The method may also include recreating the un-stored parities after a time interval that may be specified by a user.

公开了一种增强RAID级别3的方法和系统的方法和系统。 在一个实施例中,一种方法包括将数据驱动器的物理存储容量分配三次到独立磁盘的冗余阵列的“n”个物理驱动器的专用奇偶驱动器,从而恢复“n”个的n-1个物理驱动器故障, 通过奇偶校验技术的物理驱动器,其中在数据的初始写入期间产生的某些数量的奇偶校验可被物理存储,并且使用应用于所存储的奇偶校验的XOR函数来重新创建未存储的奇偶校验, 1个物理驱动器故障。 该方法可以包括通过镜像创建优异的读/写访问能力和/或更高的奇偶校验数据冗余。 该方法还可以包括在可由用户指定的时间间隔之后重新创建未存储的奇偶校验。
