Assume a disk subsystem with the following components and MTTF:

5 disks, each rated at 2,000,000-hour MTTF

1 SCSI controller, 500,000-hour MTTF

1 power supply, 200,000-hour MTTF

Using the simplifying assumptions that the lifetimes are exponentially distributed and failures are independent, compute the MTTF of the system as a whole.
