Normally to eliminate the cache effect, you run iozone and other
benchmark suites at 2x the ram. However, we can't do that due to 2TB
> 1.3TB.
So, does anyone have any suggestions/experiences in benchmarking
storage when the storage is smaller then 2x memory?
Oracle's Orion test tool has a configurable cache size parameter - it's
a separate download and specifically written to benchmark database oltp
and olap like io patterns, see
