A customer needs a very small AIX system to run their new application and is considering a 1-way p615.  What key information should the pSeries technical specialist provide to the customer？（）

A customer has two different applications， each requiring two processors.  They are evaluating the following three alternatives：  
1） Two p5-520s each with two processors and 4GB memory  
2） One partitioned p5-550 with four processors and 8GB memory  
3） One partitioned p5-570 with four processors and 8GB memory  
All three solutions will work.  However， when helping the customer decide which solution is best for their environment， the pSeries technical specialist should convey which of the following pieces of information？（）
