While doing a Disk Magic study and viewing the baseline results of the imported Iostat information
from an AIX server, you notice a large number of large random writes while the application server
was doing a batch load. This batch job currently takes 12 hours, which exceeds the customers 8-hour requirement. This batch job currently is running on a 22TB’s of DS4200 with 500 GB SATA
drives. What should you suggest to decrease this batch job time and limit the overall cost?

A.
DS3400 with 1TB SATA drives

B.
DS4700 72A with 750 GB SATA drives

C.
DS5100 with 450GB 15K FC drives

D.
DS3400 with 300GB 15K FC drives
