A. 1 SSD drive for the caching tier and 1 or more SSDs for the capacity tier
B. 1 SSD drive for the caching tier and 1 or more HDDs for the capacity tier
C. 2 or more SSD drives for the caching tier and 2 or more HDDs for the capacity tier
D. 2 or more SSD drives for the caching tier and 2 or more SSDs for the capacity tier
Definitely A&B.
