Who is responsible for the installation and set up of the storage server（）

A customer’s SAN environment has undergone significant growth over the past two years. They have also suffered a high turnover rate with administrative personnel. The customer has asked a storage specialist for help in documenting and understanding their changing SAN environment. The ability to make configuration changes to devices would be a plus. 
Which tool should the storage specialist suggest（）

The Business Partner technical specialist is called to determine if the addition of host ports on an IBM System Storage DS8700 has improved users’ response times for an IBM System p server running SAP. 
How can the improvement be verified（）

A customer with a single IBM System Storage DS8100 reports severe performance problems for some of their applications when a particular data warehousing application creates a heavy load. 
What is the most cost effective way to resolve this issue（）

A customer recently installed new a SAN with an IBM System Storage DS8700 and several open systems servers to address a need for storage consolidation and still provide good response time. They have asked the Business Partner technical representative for the most complete IBM product that would allow them to do performance reporting of the new SAN environment.
