Proteus is an open-source simulation program that can predict the risk of data loss in many disk array configurations, among which, mirrored disks, all levels of RAID arrays and various two-dimensional RAID arrays. It characterizes each array by five numbers, namely, the size n of the array, the number nf of simultaneous disk failures the array will always tolerate without data loss, and the respective fractions f1, f2 and f3 of simultaneous failures of nf + 1, nf + 2 and nf + 3 disks that will… CONTINUE READING
