B.The p5-570 allows for more CPU and memory resources to be dynamically allocated to any LPAR for performance testing.
C.The p5-570 can only be upgraded to 64GB of RAM without replacing memory.
D.The p5-570 supports advanced features such as Micro-Partitioning and Virtual I/O allowing more LPARs of the customer’s applications with fewer processors and fewer I/O adapters.
