What is used to gather information on a Windows host that will be used for determining the optimum configuration of an IBM System Storage DS8700（）

A customer would like to implement an IBM System Storage DS8000 solution that requires 225 TB raw capacity. They are convinced that 450 GB is the optimum size for their business applications. There is limited space available for additional machines in the data center. 
Which solution meets best this requirement（）

A customer wants to consolidate storage from four IBM System p servers and one large IBM System i server on a high end disk subsystem. The customer does not have a SAN installed. The customer will require approximately 24 TB of capacity for System p and 20 TB of capacity for System i. The customer states that performance of the System i system is most important. Capacity， multi-path access， and replication functions are important for the System p servers. 
Which solution best satisfies the customer requirements（）

An IBM System Storage DS8700 is being installed at a global corporation’s headquarters location. The storage must be available worldwide. A great deal of coordination is required to schedule this implementation across the corporation.
