(What is the performance improvement in sequentially reading the complete file when compared to a single drive subsystem in terms of the number of operations performed? We have 5120 segments to write to raid disks. Given 4 disks we have 1280 actual 1/Os to perform On I drive we clearly have 5120 operations to perform (ii) What is the percentage performance improvement expressed as the number of physical 1O operations to be executed in on the RAId and single drive systems? The improvement is (5120-1280)1280*100=300% Obvious given 4 concurrent drives and RAID 11 MARKS-- UNSEEN(i) What is the performance improvement in sequentially reading the complete file when compared to a single drive subsystem in terms of the number of operations performed?
