After analysing a number of arrays that have between 300 to 1,000 virtual machines running against them, we have found that on average, the following workload and skew numbers are fairly representative of these environments:
I am looking at doing modelling to replace 3rd party arrays, but do not have any modelling data and the arrays are not supoported under the MiTrend data collection tools.
What read/write workload and skew do I use for modelling a large virtual 
environment if I am unable to collect statistics from 3rd party arrays?
