this basically means that if you are creating a pool of suppose 1 TB, you can create 10*100GB TDAT's OR 20*50GB TDAT's OR 40*25GB TDAT's and so on, BUT we dont want the number of tdat's to be too high, data is striped on tdat's in the pool, we want every spindle to be used atleast once,creating too many TDAT's will cause the same spindle's to be used multiple times which can degrade performance.  
Hi Experts,  I'm reading the technical notes about the Best Practices for Fast, Simple Capacity Allocation with Symmetrix Virtual Provisioning Technical Note. I have some question about the content of Thin pool considerations on page 27:  "Data device sizes should be as large as possible to minimize the number of devices required to encompass the desired overall pool capacity."  "Each drive must be divided into at minimum eight hypers in order to maintain adequate disk queue depth."  I don't fully understand above sentences, can anyone help on this?
