I am looking for a calculator or method to calculate the IOPS for a given drive, i.e. 300GB - 15K - 4GB Fibre Channel Drive or a 146GB - 10K - 4GB Fibre Channel Drive.
I would like to deploy Exchange 2007 and the database LUN requires 3000 IOPS to perform optimally. Also how does these IOPS per drive differ from Raid 1+0 and Raid 5?
Knowing my IOPS, I need to know what drive count + Raid config is best.
Any assistance will gladly be appreciated.
