Many times my colleagues ask me how to determinate IOPs on their RAID or storage. There are a lot of posts on internet and for this reason I don’t want to create another copy of the same content.
Of course you have to calculate IOPs based on disks that you have. Not all the disks are the same and real IOPs can vary, based on the model of the disk. How to calculate IOPs of the disk is well explained in this link http://www.techrepublic.com/blog/the-enterprise-cloud/calculate-iops-in-a-storage-array/. But if you want just an approximate calculation of your RAID field, you will like this link http://www.thecloudcalculator.com/calculators/disk-raid-and-iops.html. It is approximatively as IOPs depend on actual mark and model of disks, RAID controller or NAS, but it can be used as a guideline to determinate your configuration..
