The IOPS required to support an application is calculated based on the percentage of read IO, the percentage of write IO, and the write penalty of the RAID level the workload will be hosted on.
To calculate the IOPS requirements, perform the following steps:
- Determine the number of IOPS a workload requires
- Identify the percentage of read IO to write IO for the workload
- Determine the write penalty of the RAID level that will host the workload
- Calculate the IOPS the storage must be capable of providing to support the workload
