A storage specialist wants to create a fixed-block volume in the extent pool P10， in rank group 0. 
Which of these volumes cannot be created（）

mainframe customer would like to receive a proposal for a mainframe storage system with 120 TB raw capacity. The 
mainframe server load is not too high， and they need hard disk drives with the lowest possible power consumption to keep operating costs low. The customer will not increase the capacity of their mainframe applications in the future but rather invest later into their System p servers. 
Which of the following solutions best meets these requirements at the lowest cost（）

A customer wants to collect performance data from a newly installed IBM System Storage DS8700 to determine if the system meets expected benchmarks using their application test data. 
Which tool best gathers the performance data（）

A company has a 30 TB multi-vendor storage environment attached to System i and open systems. They are concerned about the time and effort caused by frequent migrations to new storage hardware for open systems data. In addition to consolidating their storage to a single platform， they would like to take advantage of advanced features such as Easy Tier and implement a three-site business continuity strategy. 
Which product provides the best long-term solution for this company（）

A storage specialist needs to create a new host connection using the DSCLI. 
Which of the following parameters identifies the host（）

A customer using an IBM System Storage DS8700 is facing performance problems. After the analysis by the technical specialist， the diagnosis indicates that the cache hits may be improved by a cache upgrade. 
How can the system be monitored in order to check the benefits of the cache upgrade（）
