Which two benefits does Hitachi Thin Image provide? (Choose two.)

A customer is using HUS 150 arrays in two sites 500 meters apart. They have 10 GbE connectivity between the data centers. The customer must set up a clustering solution with array-based replication requiring data currency.

What would meet the customer's requirements with no additional hardware?

A customer has a HUS 130 array and wants an asynchronous solution. The customer needs to understand which factors influence the TrueCopy Extended Distance cycle time.

Which two factors should be considered? (Choose two.)

Your customer has a 300 Mbps line but is unable to get more than 10 Mbps throughput from the Hitachi Universal Replicator pairs.

Which system option mode (SOM) setting is causing this problem?

A customer is replicating a database with a five minute RPO between two HUS 150 arrays. They have workload bursts that exceed their available bandwidth.

Which replication technology would meet this requirement?
