A customer has two Power 570 servers that need to be replaced to accommodate company
growth.
The first server runs a transactional workload with high server usage during the day (8am-8pm)
The second server runs analytic queries based on the transactional data during the night (10pm-
6am).
A technical sizing analysis determined that each server would require (18) POWERS 3.52GHz
cores and 160GB RAM, considering the needed growth.
What would be the most cost-efficient way to satisfy the customer needs?
A.
(1) new Power S824 with 24 cores and 384GB and DLPAR CPU resources among LPARs
B.
(1) new Power 770 with 36 active cores and 384GB active, virtualized with capped LPARs
C.
(1) new Power S824 with 36 cores and 384GB, virtualized with capped LPARs.
D.
(2) new Power S824 with 20 cores and 192GB RAM each.
Explanation:
A 18 core are enough

It would help if the authors would correct typos, POWERS should read POWER8.
Read the question: A technical sizing analysis determined that each server would require (18) POWERS 3.52GHz cores and 160GB RAM, considering the needed growth.
The key words here is “each server” and 3.52GHz.
1. The 770 does not have a 3.52GHz processor.
2. “each server” means two servers.
D has to be the answer because it meats all the criteria: two servers, 3.52GHz processor, up to 24 cores and memory.

Correcting my own answer.
A is the most cost efficient and will get the job done.
