  author={Jakub Sikora},
In large-scale systems where number of components c an approach a million a failure is a significant problem. In this paper aut hors have presented and analyzed failure data from different large systems. More than 100,000 disks with different interfaces which come from at least four different vendors have been investigated. According to information which o ne can find in datasheets the annual failure rate should be at most 0.88%, bu t the results show that replacement rate is usually in the… CONTINUE READING
