Question
Chapter 4.S, Problem 8P
a)
Summary Introduction
To determine: The decrease in the reliability of plan 1.
Introduction:
Reliability:
Reliability can be termed as the measure of the capability of a product or any service to perform its intended job under a predetermined set of conditions. The product or service will yield the same results on the repeated trials. It is the degree of consistency of a measure.

The reliability of each component over the anticipated lifetime and its cost are given in the table below. You already have one component for each kind, you may purchase additional components and operate them in parallel (add redundancy) at each stage. Assume a budget of $20 is available. What is the maximum possible system reliability? How many additional components of each type should be purchased? component: 1 , 2, 3 Reliability: 0.9, 0.8, 0.7 Unit cost: 9, 4, 3arrow_forward

- Assume that a computer has two 1TB disks, D0 and D1. The Mean Time to Failure (MTTF) ofeach disk is 1M hours.a. If the disk system is configured to have 2TB total storage capacity, when any of the two disksfails, the disk system fails. What is the MTTF of the disk system?b. Mirroring (RAID-1) is a technique can improve the reliability of disk systems by usingredundancy. Each data block will have two identical copies stored in both D0 and D1. Under thisconfiguration, the disk system has only 1TB total storage capacity; but it only fails when bothdisks fail (e.g. when the failed disk is being repaired, the second disk also fails). If the MTTR of afailed disk is 20 hours, what is the MTTF of the disk system now?arrow_forwardIn the context of system reliability, explain the difference between Mean Time Between Failures (MTBF) and Mean Time To Recovery (MTTR).
