Has anyone used the SQLIO tool from microsoft?

I found that the best configuration for io highest mb/s for one of my servers is

sqlio.exe -kR -t25 -s30 -f25 -b1024 -i128 -BN testfile.dat

25 threads, 25 stripe size in blocks, 1024 blocks, 128 ios per run.

How would I make sure sqlserver is tuned with this?
What are the default settings for the above in sql server?
Should I make any changes at the OS level and if so where?
Should I make any changes to drivers?
Should I make any changes to array controller?

Thank you ahead.
