Mean Time Between Failures (MTBF), Mean Time To Replacement (MTTR), and Mean Time To Failure (MTTF) are useful metrics for evaluating the reliability and availability of a storage resource. Explore these concepts by answering the questions about devices with the following metrics. Given: MTTF = 3 years, MTTR = 1 day (a) Calculate (i) MTBF and (ii) availability.
(b) What happens to availability as the MTTR approaches 0? Is this a realistic situation?
(c) What happens to availability as the MTTR gets very high, i. e., a device is difficult to repair? Does this imply the device has low availability?
