Abstract
Disk capacities and processor performances have increased dramatically ever since. With rising storage space the probability of failures gets higher. Reliability of storage systems is achieved by adding extra disks for redundancy, like RAID-Systems or separate backup space in general. These systems cover the case when disks fail but do not recognize corrupted data in faulty blocks. Especially new storage systems like Solid State Drives are more vulnerable to corrupted data as cells are “aging” over time. We propose to add error detection and correction of data to a RAID-system without increasing the amount of space needed to store redundancy information compared to the common implementation RAID 6. To overcome higher computation complexity the implementation uses parallel execution paths available in modern Multicore and Multiprocessor systems.
