1(a) Calculate the storage efficiency of RAID level 1, 3, 5 and 6. The number of disk drives available are 6 each having capacity of 200 GB. Also find out usable capacity of each RAID level.
1(b) Consider a disk I/Osystem in which an I/0 request arrives at a rate 100 IOPS. The service time Rs=8ms. Calculate the following measures of disk performances: 1) Utilisation of I/O controller (U). 2) Total Response Time (R). 3) Average Queue Size. 4) Total time spent by request in the Queue. If the service time is half i.e. Rs=4ms and I/O request arrives at a rate of 100 OPS, them calculate the following measures of disk performance: 1) Utilization of I/O controller (U) 2) Total Response Time (R) 3) Average Queue Size. 4) Total time spent by request in the Queue.
