Calculating storage throughput

The data transfer rate or throughput is the rate at which data can be read from or written to the storage device and is typically measured in MB/s.

How to do it...

Throughput should be calculated in order to ensure that the storage controllers and disk can support the required data transfer rates. Throughput is also used to correctly size the storage connectivity bandwidth.

To calculate storage throughput requirements, perform the following steps:

  1. Determine the I/O size of the workload.
  2. Determine the number of IOPS required to support the workload.
  3. Calculate the throughput required.

How it works...

Throughput is calculated by multiplying the I/O size of the workload by the number of IOPS. Transactional databases and application ...
