Storage Network Management And Retrieval - May 17

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. (i) Consider an application that requires 1 TB 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

For rotational latency RPMs = 15,000 rpm

Average seek time = 5ms

Transfer rate: 40 MB/s

(ii) Considering seek time (Rs=5ms) as given above and I/O request arrives at a rate 100 I/Os per second.

Calculate Utilization of I/O controller (U), Total Response time (R), Average Queue size and Total time spent by request in a queue.

(10 marks) 12421

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 6 and each disk has storage capacity of 100GB.
