   EMC Best Practice:
   The calculation for determining logging volume size is: 10 GB protects 320TB/N [n is the number of clusters]

   As per the VPlex Admin Guide;

   For a 160TB DD, a logging volume of approx. 10GB at each cluster is required.

   Hence, with a 20GB logging volume, you can manage 160GB x 2 = 320GB.

   Correct answer is B.

   Sure B!

   2 bit per 4K request => 1 byte per 16k data => 10 Gbyte per 160 TB data
