Running bonnie++ with this cmd on a RHEL 6 server with a striped FS across several LUNs from a FibreChannel SAN array:
bonnie++ -d /sys_apps_01/splunk -s 512G -u splunk -fb
The bonnie++ result is: 189 Random Seeks
BUT.... The array reports 14,000 IOPS and 1.4GB/s throughput for the duration of the test.
Why the discrepancy between the bonnie++ results and the array reporting? The array is seems to be doing a massive amount of work for the test, but the bonnie++ application is not "feeling" all the work the array is performing.
Are there any "tweaks" that need to be made to the FS or IO Scheduler? Any other HBA driver tweaks that would be recommended?
Any help would be greatly appreciated!
Thanks!!!!
Aaron
