Consider the following system with disks 1,2 and 3. -- 10 Disk 1s with 1,000,000-hour MTTF -- 19 Disk 2s with 450,000-hour MTTF -- 1 Disk 3s with 700,000-hour MTTF -- MTTR for single disk is 8000 hours and 13,000 hours for the system -- p(disk) is 1 -- G is 5 (a)Find the MTTF of the system. (b)Use the MTTF found above, to find the Reliability and MTTDL. Which RAID level is best for each failure characteristic
