A customer has asked you to design a NAS solution for their file sharing environment that will include SnapSure technology to complement their backup strategy. The current storage environment for file system usage is 5 TB. The customer expects a 10% rate of change per checkpoint and expects a total of 20 checkpoints.
How much additional space is required for the checkpoints?

A customer recently added two new applications to their CLARiiON environment.Application A is a reporting/data warehouse with a performance profile of primarily sequential read activity. Application B is a customer service application with a performance profile containing high numbers of random writes.
When the applications were deployed. The LUNs were created on a sungle 8+1 RAID group.The customer is experiencing performance problems throughout the day. They cannot understand the reason for the problems since only the LUNs for these two applications are on the RAID group and capacity utilization is less than 50%. No other LUNs are experiencing degraded performance at this time. What should the customer do to resolve the performance problem?

A customer is designing an environment in order to archive inactive file data to an EMC Centera.
The files are migrated to the EMC Centera only if they have not been accessed in the last 90 days.
The customer also requires a comprehensive disaster recovery solution to restore all the data in the event of a disaster. They are currently replicating the EMC Centera to Site B.
The customer has asked you to review their design. What should you suggest to the customer to meet their requirements?

A customer has shown you a design for EMC Centera replication between sites. In the event of a single site failure, what must be added to the design to ensure data availability?
