A prospective customer has presented you with multiple applications. All applications have high write activity levels and unpredictable growth patterns. The applications are currently hosted on directattached storage in a RAID 1 configuration. They are concerned with making too many changes at one time in their environment.
The prospect has asked you to justify your recommendation of RAID 1/0 on the CLARiiON configuration you are proposing. How do you respond to the request?

A.
RAID 1 has a higher write penalty than RAID 1/0

B.
RAID 1 is less flexible for growing LUNs than RAID 1/0

C.
RAID 1 is unavailable in current CLARiiON configurations

D.
RAID 1 LUNs are unable to utilize write cache
