Your customer needs to expand their storage infrastructure. Their current subsystem design
implements DS4800 88A with 750GB SATA drives and DS5300 with Fibre channel 15K 146GB
drives all behind a 2 Node SAN Volume controller. The customer wants to know when they should
add additional controllers versus additional capacity to an existing subsystem without jeopardizing
any system performance. The customer has agreed to pay for you to do this study. What tools
would you use to determine this?

A.
Install / configure and utilize SSPC and Capacity Magic

B.
GatherIOstat information from the host applications and use Capacity Magic

C.
GatherIOstat application information and utilize SSPC

D.
Use Disk Magic to find the saturation points of the SVC, and the DS storage subsystems
