ABC.com, who uses Windows and AIX servers in its environment, is a nation-wide home building
company that currently employs a CLARiiON CX600 with ninety 73GB drives for its data
processing needs. This data is spread across fifty RAID-5 40GB LUNs. ABC.com creates Clones
of their data for daily backups and weekly reports, both of which are read-intensive applications.
ABC.comneeds to create a further copy of its production data, for future development and testing
of new applications. This copy of the data will be write-intensive. ABC.comis not keen on
expending yet another full copy of data storage for its development and test requirements. Which
of the following solutions would you advise ABC.comto use?

A.
Propose a CX700 with RAID-1 protection for production volumes. Use SAN Copy to migrate the
data from the CX600 to the CX700. Create RAID-5 Clones for the test and development data. Use
Snapshots for space efficient copies for backups and reports.

B.
Propose a CX700 with RAID-5LUNs for the production volumes. Use SAN Copy to migrate the
40GB LUNs to larger 100 GB LUNs. Use RAID-5 Clones to replicate the data for test and
development. Use Snapshots to generate space efficient copies for backups and reports.

C.
Use the available capacity on the existing CX600 to create another set of Clones. CX600 limits
allow 100 Clones.

D.
Propose a CX700 with RAID-5 protection for production volumes. UseMirrorView/A to migrate
the data from the CX600 to the CX700. Create RAID-1 Clones for backups and reporting. Create
Snapshots for the test and development copy to save space.
