A small law firm that does not currently have any virtualization technologies implemented has recently merged with another firm of approximately the same size. They are planning to consolidate into a single location. They have decided to virtualize their servers and they would like to consolidate storage. It has been determined that 80% of the file server data has not been accessed in over 90 days.
What can they implement to achieve higher storage efficiency?
A. A file archiving plan, to leverage inter-array storage tiering
B. Quotas, to limit the amount of capacity users or groups can consume
C. File extension filters, to prevent non-business related data from being stored in home directories
D. Vertical storage tiering, to ensure data is placed on the appropriate drive technology
