Assume a disk subsystem with the following components and MTTF:
i) 10 disks, each rated at 1,000,000 hour MTTF:
ii) 1 SCSI Controller, 5,00,000 - hour MTTF
iii) 1 power supply, 2,00,000 - hour MTTF
iv) 1 fan 2,00,000 - hour MTTF
v) ISCSI cable, 1,000,000 - hour MTTF.
Using the simplifying assumptions that the lifetimes are exponentially distributed and that failure are independent, compute the MTTF of the system as a whole.
