Subject: Helping to model this workload

Hi All

This is neto from Brazil

How are you?

I need to model the following workload:

Sequential Read % 35.0
Sequential Write % 5.0
Random Read % 50.0
Random Write % 10.0
Random Read Working Set(GB) 1000.0
Random Write Working Set(GB) 1000.0
Sequential Read Size(KB) 64KB
Sequential Write Size(KB) 64KB
Random Read Size(KB) 8KB
Random Write Size(KB) 8KB

For the random workload � I thought to use 16 jobs with 2 outstanding IOs.
For sequential workload, I cannot use more than one job (because this will
become random) and I need to use 64 outstanding
 Ios.

My biggest doubt is: how to distribute the percentage in the job file?

Does anyone have any example to share?

Thank you very much

All the best

neto
