Application A has its consistent peak workload of 25 K IOPS with an average 8 KB blocksize for 3
hours from 10 A.M.
Application B has its consistent peak workload of 25 K IOPS with an average 4 KB blocksize for 4
hours from Noon
Application C has its consistent peak workload of 45 K IOPS with an average 4 KB blocksize for 3
hours from 1 P.M.
Application D has its consistent peak workload of 15 K IOPS with an average 4 KB blocksize for 4
hours from 11 A.M.
