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. 10 marks

1(b) Consider a disk I/Osystem in which an I/0 request arrives at a rate 1001 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) Utilisation of I/O controlller (U)
2) Total Response Time (R)
3) Average Queue Size.
4) Total time spent by request in the Queue.
