A node in a cluster fails every 200 hours of operation while other nodes never fail. On failure of
the node, the whole system needs to be shutdown. It takes 1 hour to replace the faulty node and to
bring up the cluster. Then the application needs to be started again. This takes another 1 hour. The
production loss is $100k per hour. [Marks: 4]
What is MTTF in this case?

2. What is the availability of the system?
3. What is the cost of downtime per year?
