How to calculate IOPS in Exadata ?

When we think to calculate IOPS , it seems very difficult task but it’s very easy to calculate in Exadata Storage. Let’s understand the procedure to calculate IOPS.

Well, first of all, execute the calibrate command on all available cell storage.

We are doing testing on Exadata Database Machine X3-2 1/8^th rack. Same procedure can be followed on any configuration of Exadata.

Cell Server 1

CellCLI> calibrate force

Calibration will take a few minutes...
