   D is not right!
   In business class DS8870 maximum number is 1056 which is not present.
   In Closest number is C 1028.
   But test is outdated and may refer to older configurations
   so may when limit was 144 (search tips1012.pdf)
   So it is either B or C

   Improved high density frame design:

   The DS8800 can support a total of 1536 drives in a smaller footprint (three frames) than
   previous generations, supporting higher density and helping to preserve valuable raised
   floor space in data center environments. DS8800 is designed for hot and cold aisle data
   center design, drawing air for cooling from the front of the system and exhausting hot air at
   the rear.
