| # Sample job file demonstrating how to use zoned random distributionss |
| # to have skewed random accesses. This example has 50% of the accesses |
| # to the first 5% of the file (50/5), 30% to the next 15% (30/15), and |
| # finally 20% of the IO will end up in the remaining 80%. |

| random_distribution=zoned:50/5:30/15:20/ |
| |
| # It's also possible to use zoned_abs to specify absolute sizes. For |
| # instance, if you do: |
| # |
| # random_distribution=zoned_abs:50/10G:30/100G:20/500G |
| # |
| # Then 50% of the access will be to the first 10G of the drive, 30% |
| # will be to the next 100G, and 20% will be to the next 500G. |
| |
| # The above applies to all of reads/writes/trims. If we wanted to do |
| # something differently for writes, let's say 50% for the first 10% |
| # and 50% for the remaining 90%, we could do it by adding a new section |
| # after a a comma. |
