Unfortunately we don't have experience with NexSAN.
HDS are quite conservative and with a value of 8 we run quite stable (with UFS).
Also we found that value appropiate for old HP EMA arrays (old units but very 
very reliable! Digital products were rocks)

 HDS provides an algorithm for estimating
 sd[d]_max_throttle in their
 planning docs.  It will vary based on a number of
 different parameters.
 AFAIK, EMC just sets it to 20.

you're right but after -a lot- of tests we found 8 to be the best value..

For the particular HDS array you're working on, or also on NexSAN storage?
