Suppose a given server computer has a distributed file system on 3 disk drives. The distribution is for speed, not redundancy, so if any one of the three disk drives fails, the computer fails as a whole- it cannot serve any requests. Now suppose that that the MTTF for each of the 3 individual disk drives is 1 year. What is the MTTF of the disk drive subsystem consisting of the three drives working together. There is no other hardware in the subsystem except the three disk drives.
