The exhibit represents a report from Capacity Magic. A customer wants to implement a mixed Open and System z environment. They will be using a combination of SSD, SAS and Nearline SAS drives. System z will require PAV. The NL-SAS drives will be used for FlashCopy targets for Open Systems and for Historical Report Data for z/OS. They wish to use Metro Mirror to replicate the Opens Systems production data to a remote site.

Which of the following best describes the minimum license requirements?

A. OEL = 258TB, MM = S7TB, FlashCopy = 87TB, PAV = 87TB, FICON = Yes

B. OEL = 258TB, MM = 258TB, FlashCopy = 258TB, PAV = 258TB, EICON = Yes

C. OEL = 173TB, MM = 87TB, FlashCopy = 48TB1 PAV = 87TB, FICON = Yes

D. OEL = 258TB, MM = 141TB, FlashCopy = 141TB, PAV = 1 17TB, EICON = Yes

B. RAID 0 because archive data isn't mission critical and they should use tape backup

C. RAID 10 because this is the only protection supported for NL-SAS drives

D. RAID 5 because data on these drives is less critical than the production data
