Your Company wishes to deploy a new streaming media application using large multimedia files for their employees to use as a training tool, and they would like to store the media files on their CLARiiON CX4 array.
The performance in their proof of concept has not been acceptable, and they have narrowed the problem down to their disk. They deployed the application and data files on a single RAID 5 4+1 LUN. The application data has various I/O sizes, and the media file I/O size is 1024 KB. The customer is confident the application will perform adequately on the CLARiiON, but they are unsure what changes they should make to the configuration. What would you recommend the customer change in their configuration to achieve the highest performance?

A.
Place the media files on a RAID 5 group and the application files on a RAID 3 group.

B.
Place the media files and application files on separate RAID 5 4+1 groups.

C.
Place the media files and application files on separate RAID 1 groups.

D.
Place the media files on a RAID 3 group and the application files on a RAID 5 group.
