A customer is concerned about the high energy cost associated with their data center. Specifically， their concern focuses on the cooling cost of many hundreds of servers. You have a meeting with the CIO and CFO to propose a solution.  How would you prepare yourself for the meeting？ （）

• A、Since their capacities and usage models vary， ask the customer to turn off some of the servers during off-peak and low demand time.
• B、Investigate their expansion plans and suggest to the customer the removal of some of their servers to another location and retirement of the older servers.
• C、Contact the CFO to find out the targeted energy savings of the company and propose to the customer the purchase of a more efficient cooling system.
• D、Contact the CIO for a list of servers and type/model numbers. Complete a proposal outlining the savings on energy cost by deploying an IBM BladeCenter solution and total cost of ownership and return on investment.
