A company wants to buy memory efficiently on their p5 590 to allow for the best performance. What is the best practice for adding memory for performance?（）

• A、Install more cards of smaller capacity and same size across MCMs. Use DDR2(dual data rate) memory if using HPC (High Performance Computing). 
• B、Install fewer cards of larger capacity of the same size across MCMs. Servers with one processor book must have a minimum of four memory cards installed. 
• C、Intermix DDR1 and DDR2 memory so that partitions requiring the higher performance can take advantage of them. Half of the available memory slots in the system should contain memory. 
• D、Use fewer higher density memory cards so that a few memory slots are left open for future growth. Each processor book provides sixteen memory card slots. The p5 590 supports a maximum of 64 memory cards.

第14题：

Companycom is considering a partitioned solution which will require cumulative rPerf total of 150. The original sizing came back recommending a 32-way p5 590. However, they have a requirement for future scalability and availability is important. Which of the following would be the best reason to recommend a p5 595?（）

• A、The p5 595 would allow for COD
• B、The p5 595 includes the Advanced Power Virtualization hardware and software
