Demo Question 4.

Delta Devices has contacted EMC to solve its backup infrastructure problem. Its current backup infrastructure consists of several different types of backup software and tape drives, dedicated to its own servers. After several meetings you designed a centralized backup infrastructure, implementing backup to disk technology. EliteCertify.com is very concerned about disaster recovery times. You propose one CX500 with ATA disks to be used onsite, at the primary location, and another CX500 at a secondary location so backup data can be replicated from one CLARiiON to the other one through the WAN. This will ensure that the backup data will be available in case of a major disaster with the primary location. What other action should be taken?

A. Replicate backup software catalog
B. Enable the write cache on the target CX500
C. Set the backup software block size to match the CLARiiON stripe size
D. Tune the backup software block size for remote replication
