A customer is considering multiple options for a particular set of workloads on AIX v5.2. They need to run ten identical LPARS， each containing four fibre cards， two 2-port Ethernet cards， and one SCSI card as well as two internal boot disks. They want the LPARS to be split across two physical systems for redundancy purposes； cost is an issue. They need a total of approximately 40 rPerf for all ten workloads. Which of the following solutions best fits these needs？（）
A
2 x p655 1.7ghz 8-way servers （21.87 rPerf each）
B
2 x p670 1.5ghz 8-way servers （24.18 rPerf each）
C
2 x p690 1.7ghz 8-way servers （27.11 rPerf each）
D
2 x p650 1.45ghz 8-way servers （18.67 rPerf each）
