You work as a design specialist at Certkiller .com. Certkiller .com has four applications (A, B, C, and D) that run daily as follows:
1. A has its consistent peak workload of 20 K IOPS with an average 8 KB blocksize for 3 hours from 10am
2. B has its consistent peak workload of 25 K IOPS with an average 4 KB blocksize for 4 hours from midday
3. C has its consistent peak workload of 25 K IOPS with an average 8 KB blocksize for 3 hours from 1pm
4. D has its consistent peak workload of 15 K IOPS with an average 4 KB blocksize for 4 hours from 11am

You need to ensure best performance while incorporating 25% growth.
What is the minimum number of 2 Gbit array ports Certkiller .com should use to handle this workload as well as the 25% growth into a single array?

A.
5

B.
4

C.
3

D.
2

E.
1

Explanation:
Take all workloads, graph them, iops * size = megs/sec and each port takes 200 meg/sec, take the largest peak workload + 25% and divide by 200, round up to get answer.
