Information Technology (Semester 8)

Total marks: 80
Total time: 3 Hours INSTRUCTIONS
(1) Question 1 is compulsory.
(2) Attempt any three from the remaining questions.
(3) Draw neat diagrams wherever necessary.

1.a. Consider an application that requires 1TB of storage capacity and performs 4900 IOPS. Application I/O size is 4kB. As it is business critical application, response time must be within an acceptable range.

Specification of available disk drive:

Drive capacity = 73 GB; 15,000 rpm; 5 ms average seek time; 40 MB/s transfer rate

Calculate the number of disks required?

(10 marks) 12420

1.b. An application that generates 3600 IOPs with 60% reads and 40% writes. Calculate the IOPs generated for RAID level 1, 4 and 6. Also calculate storage efficiency and usable capacity for RAID levels 3, 5 and 6 with number of disks available are 5 and each disk has storage capacity of 120 GB.
