How to calculate IOPS without using Bonnie++ ?
Trying to determine the 800-1200+ IOPS requirement is being met based on http://wiki.splunk.com/Community:HardwareTuningFactors
I'm not able to install Bonnie++ due to company restrictions. How can I calcualte IOPS? Runing on RedHat Linux 6 (2.6.18-238.9.1.el5 #1 SMP Fri Mar 18 12:42:39 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux)
I have some data below but not sure how to translate it into IOPS.

If you can grab the binary version of bonnie++, you don't really need to install it in order to run it. You can just run it off as a normal user, provided you have write access to the volume path that you are interested to perform the benchmarking on.
The IOPS that Splunk recommends are based on Bonnie++. So if you are using other benchmarking utilities it will be challenging as the figures will varies.

So is IOPS synonymous with TPS? I do have tps in the results above.
Fromt he link you sent:
What's IOPS?
IOPS - I/O operation per second, also can be transaction per second(tps)
Thanks,
Rob
