Howdy all, We're attempting to run some performance tests on a Solaris 11.2 system with ZFS. The system has a sizable amount of memory which is currently more than the available space left in ZFS. Given that ZFS does not provide for direct IO, we're looking for options on how to exhaust the caching and actually test the throughput of the underlying disks. I've looked through several of the fio options but so far have not been able to find a mix that would let us do more total IO than is actually used as space on disk. The idea we had was to lay down say a 100GB file, but do 200-300GB of actual IO within that single (or multiple) file(s). Does anyone have experience perf testing ZFS and might have some suggestions to tackle this scenario? Thanks! -Spencer -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
